    This paper proposes an agent communication system, in which many communication system's elements, such as communication services, charging and network operation functions, are expressed as agents and multimedia communication services are offered that multi-agents negotiate with each other. The agent communication system is the third communication system. The first communication model is the circuit communication model for telephone services, and the second communication model is the packet communication model for data communication services. The agent communication model is based on the concept of distributed cooperative agent-oriented networking. First, an agent-oriented software architecture is introduced for supporting multimedia communication services in wide-area networks. Multimedia services are expressed as agents. Next, this paper proposes an agent request broker for multimedia communication services in an agent communication wide-area network. The agent request broker is the platform for multi-agents, which is based on the concept of agent-oriented software. Furthermore, a five-layer agent communication networking architecture is proposed. Finally, personal communication telephone services, video-mail services and video-on-demand services are presented by using the agent communication system's experimental setup of IP-over-ATM View full abstract»

    Message Dissemination under the Multicasting Communication Mode

    Gonzalez, T.F.
    Parallel and Distributed Computing, Applications and Technologies, 2007. PDCAT '07. Eighth International Conference on

    DOI: 10.1109/PDCAT.2007.86

    IEEE Conference Publications

    We discuss algorithms, complexity issues, and applications for message dissemination problems under the multicasting communication mode. These problems arise while executing in a parallel or distributed computing environment iterative methods for solving scientific computation applications, dynamic programming procedures, sparse matrix multiplication, etc. Our message communication problems also arise when disseminating information over ad-hoc wireless networks. Given a communication environment and a set of messages that need to be exchanged, the message dissemination problem is to find a schedule to transmit all the messages in the least total number of communication rounds. Generating an optimal communication schedule (with the least total number of communication rounds) for message dissemination problems over a wide range of communication environments is an NP-hard problem. To cope with intractability efficient message dissemination approximation algorithms have been developed for different types of communication environments and message communication patterns (the communications that must take place). The communication environment consists of the communication network (the direct communications allowed for each processor), primitive operations (the basic communication operations allowed by the system), and the communication model (possible operations during each communication round or step). Our goal is to present scattered research results developed during the last decade to establish that the multicasting (one-to-many) communication environment is a powerful communication primitive that allows for solutions that are considerable better than those achievable under the telephone (or one-to-one) communication environment. The multicasting communication environment has been available for quite some time in parallel computing systems. We also establish that, within the multicasting communication mode, forwarding plays an important role by allowing solutions that a- re considerable better than when restricting to direct communications, even when the communication load is balanced and the network is complete (all possible bidirectional links are present). We show that off-line communication scheduling allows for considerably better solutions over on-line scheduling. However, on-line scheduling provides added flexibility and it is applicable to a larger set of scenarios. View full abstract»

    The Role of Communication Complexity in Adaptive Contextualization

    Katz, A. ; Te'eni, D.

    Research problem: Adding contextual information to a core message has been shown to be critical in improving communication quality, especially in computer mediated communication. This paper models how people contextualize messages in the face of changing communication complexity. Research question: Can changes in communication complexity that occur during the communication process explain and predict contextualization? Literature review: Theories of human communication and studies of computer supported collaboration suggest that communication complexity reflects potentially problematic conditions resulting from 1) the difference in perspective and context held by the collaborators; 2) the incompatibility between the message representation and the way it is interpreted and used by the receiver; and 3) the intensity of information exchanged between communicators. We use this definition as a basis of for developing a measure of cognitive communication complexity. The literature further suggests that higher communication complexity induces higher contextualization. Methodology: First, we conducted a pilot study to develop and validate measures of communication complexity. Second, we conducted a laboratory experiment, in which 258 participants working in pairs collaborated on a sixteen-step assembly task. They used a tailored system that structured each message as core (the essence of the message) and context (additional information that explains the core and the sender's perspective). We used unbalanced panel data analysis to examine the repeated measures of contextualization and communication complexity associated with each step of the task. Results and discussion: We found that collaborators respond to changes in communication complexity at the expense of higher collaborative effort. We offer a cost-benefit framework in which, at the step level, people contextualize to reduce the communication complexity, and at the task level, they additionally consider the impact - f contextualization on task performance. The main limitation of this study was the need to structure the communication between collaborators, to control and measure contextualization. Future research can adapt and extend our measure of communication complexity to less structured communication. View full abstract»

    With the rapid development of information communication technologies (ICT) over the past decade, the nature of how organization members communicate has changed, becoming far more complex and challenging. Communication risks brought about by technology-mediated communication can sometimes be detrimental to the overall organizational function and success. We classify these communication risks into three types: reception, understanding, and action risks. We propose the notion of communication portfolio which refers to a single ICT or a specific combination of lCTs that can be used to manage any perceived risk of communication. Specifically, this study aims to examine the relationship between perceived risks (i.e., risk of reception, risk of understanding, and risk of action) in the communication process and the dimensions (i.e., content, and structuring mechanism) of the communication portfolio used for communication. We also identify communication risk factors that may accentuate the different types of risks. We develop a communication risk perception framework to illustrate the relationship between the communication risk factors, the different types of communication risks, and the communication portfolio. Finally, we illustrate how the communication risk perception framework can be applied in a real-life natural setting by using the shuttle Challenger incident, as an example. View full abstract»

    This study examines the nature, manifestations and causes of communication problems in international outsourcing engagements. Specifically, it explores a case of business process outsourcing (BPO), which is the transfer of a number of business processes, such as payroll, supply chain management, and customer relations to an external supplier. In this case, a company based in the US outsourced its business processes to a company in India. (1) If widespread proficiency in English is the reason for India's predominant position in outsourcing, then why do we hear about communication problems? (2) What are the causes of such problems? (3) In what forms and situations do they manifest? (4) How could technical communication offer solutions to ameliorate or minimize some of these communication problems? Similar cases studied include previous studies of call centers in the Philippines and outsourcing relationships in software companies have identified challenges in those relationships to problems of intercultural communications, such as language use and differences in culture. Three areas of inquiry informed this study. Intercultural communication theories provide frameworks and touch points for assessing the role of culture in communication. Previous studies of outsourcing and offshoring provided definitions of the broad range of arrangements that comprise outsourcing. Although these studies all concluded that communication is a crucial factor in the success of outsourced projects, they offered few details of communication problems, their causes, manifestations, and possible solutions. Accounts of India represent India as a rapidly-growing, dynamic economy with certain typical communication problems. The study was designed as a mixed-methods, single-case study with a mix of quantitative and qualitative methods. Quantitative data were gathered through surveys that helped develop a picture of patterns in areas such as communication problems, preferred methods of communicati- n, and patterns of escalation while qualitative data from 45 personal interviews and one group interview provided insights into the nature and resolution of communication dissonances. The case studied ABC Corporation, a captive Indian company that performed BPO for a major American corporation. Communication problems that arise in the outsourcing relationship include differences in corporate culture and differences in linguistic and rhetorical choices. Issues causing these problems include differences in education and training. Ongoing training in cross-cultural communication is needed at all stages of the outsourcing cycle, with an emphasis on communication skills in the early stages of the process, especially the hiring stage. Technical communication can offer solutions to these problems because our field can help structure suitable training applying theories such as Cross' Theory of centripetal and centrifugal forces, which provide frameworks for assessing and addressing communication problems.

    Networked Medical Systems (NMS) promise better data exchange in medical infrastructures such as operating rooms in hospitals and clinics. However, the heterogeneous interfaces of medical systems and varied requirements on NMS such as real-time constraints, increase the communication complexity considering network architectures, communication protocols and software/hardware components. In this paper, a robot-assisted eye surgery is used as a clinical use case. Based on this use case and its communication types, non-functional requirements on NMS are derived. An approach for abstraction is proposed which targets at reducing the communication-related complexity in NMS. Complexity reduction in this case means that a multi-interface middleware in NMS abstracts the detailed knowledge required for implementation of different communication types such as real-time communication. The middleware architecture is divided into two main parts: Communication Abstraction Provider (CAP) and Communication Abstraction Bridge (CAB). CAP is the central component of the middleware which connects the medical systems using CABs. In this paper, the focus is on the complexity reduction of the real-time communication part. For this purpose, real-time communication protocols are investigated and evaluated for application in the CAP/CAB architecture. The result of the evaluation shows that Ethernet POWERLINK is the most suitable real-time communication protocol for the CAP/CAB architecture. View full abstract»

    A number of serious consortiums develop satellite communication networks. The objective of these communication projects is to service personal communication users almost everywhere on Earth. The intersatellite links in those projects use microwave radiation as the carrier. Free-space optical communication between satellites networked together can make possible high-speed communication between different places on Earth. Some advantages of an optical communication system over a microwave communication system in free space are: (1) smaller size and weight, (2) less transmitter power, (3) larger bandwidth, and (4) higher immunity to interference. The pointing from one satellite to another is a complicated problem due to the large distance between the satellite, the narrow beam divergence angle, and vibration of the pointing system. Such vibration of the transmitted beam in the receiver plane decreases the average received signal, which increases the bit error rate. We review: (1) the present status of satellite networks, (2) developing efforts of optical satellite communication around the world, (3) performance results of vibration effects on different kinds of optical communication satellite networks, and (4) seven approaches to overcome the problems caused by transmitter pointing vibration View full abstract»

    Profiling the Protection of Sensitive Enterprise Multimedia Communication

    Falk, R. ; Fries, S.
    Internet and Web Applications and Services, 2009. ICIW '09. Fourth International Conference on

    IEEE Conference Publications

    Voice is, besides email, the major personal communication technology used by employees of an enterprise. Additionally, multimedia communication is getting used more and more in the form of video conferences to decrease travel cost and support environmental protection. Besides oral communication also documents, e.g. presentations, may be shared. Thus sensitive information is likely to be exchanged as part of the communication. Hence, an appropriate security level is of great relevance to protect enterprisepsilas confidential information. Historically, security measures for communication systems have either been targeted to prevent fraud, thereby securing the operatorpsilas business model, or to provide military-class end-to-end encryption. Neither approach targets the security objectives of enterprises using private and public communication infrastructure for sensitive business exchanges. It is common practice within enterprises to define different data protection classes and associated rules that have to be respected when dealing with sensitive information. Thus, the main contribution here is on one hand an evaluation of relevant available or known security technology from the perspective of protecting sensitive enterprise communication, and a roadmap for an incremental, step-wise introduction of security features in multimedia (including voice and video) communication that allows for a step-wise (incremental) introduction of security features required for different security levels.

    The 802.11-p based dedicated short range communication (DSRC) is being seriously considered as a promising wireless technology for enhancing transportation safety and highway efficiency. However, to-date, there is very little research done in characterizing the reliability of DSRC communication based on real-world experimental data, and its effect on the reliability of vehicle safety applications. Our experimental set-up includes a fleet of three vehicles equipped with DSRC communication system, GPS receiver and a number of vehicle safety applications based on vehicle-to-vehicle communication. This paper analyzes the link-level behavior of DSRC vehicle-to-vehicle communication in a wide variety of traffic environments based on real-world experimental data. In addition, we also characterize the application level reliability of DSRC for vehicle safety communication (VSC) system. Based on our experiments, we show that the reliability of DSRC vehicle-to-vehicle communication is adequate since packet drops do not occur in bursts most of the time. We also show that the application level reliability of VSC applications based on DSRC communication is quite satisfactory. Finally, we develop an analytical model to relate application level reliability with communication reliability and VSC system parameter, laying out a clear way to improve reliability of VSC applications under harsh traffic environments. To the best of our knowledge, this paper is the first to characterize the application-level reliability of DSRC communication for VSC applications based on real-world experimental data. Our findings develop a deep insight into significant characteristics of DSRC communication for highly mobile vehicle-to-vehicle wireless network, which will contribute to better design and evaluation of communication protocols for VSC applications in the future View full abstract»

    Research in computer-mediated communication has usually emphasized the cognitive over the social aspects of communication, the medium over the message, and the product of communication over the process. In contrast, this paper emphasizes three constructs of the communication process: goal-based communication strategies, message form and medium. We seek to balance cognitive and social communication strategies and to combine new and old measures of the message form (organization, formality and size). A field study in an academic institution examined the content of text-based communication delivered by letter, memo, fax and e-mail. As expected, people preferred certain message and medium attributes for certain strategies. These findings are further investigated using open-ended interviews. We conclude with examples of practical implications on designing and implementing computer-mediated communication View full abstract»

    The paper presents a novel approach to reduce communication costs of programs for distributed memory machines. The techniques are based on uni-directional bit-vector data flow analysis that enable vectorizing and coalescing communication, overlapping communication with computation, eliminating redundant messages and amount of data being transferred both within and across loop nests. The data flow analysis differs from previous techniques that it does not require to explicitly model balanced communication placement and loops and does not employ interval analysis. The techniques are based on simple yet highly effective data flow equations which are solved iteratively for arbitrary control flow graphs. Moving communication earlier to hide latency has been shown to dramatically increase communication buffer sizes and can even cause run-time errors. The authors use P3T, a state-of-the-art performance estimator to create a buffer-safe program. By accurately estimating both the communication buffer sizes required and the implied communication times of every single communication of a program one can selectively choose communication that must be delayed in order to ensure a correct communication placement while maximizing communication latency hiding. Experimental results are presented to prove the efficacy of the communication optimization strategy View full abstract»

    Chaos-based communication can be applied advantageously only if the property of chaotic systems is suitably exploited. Chaos communication has been studied for only a little more than a decade while traditional communication schemes have been developed for nearly a century. The hope was (and still is) that for some application chaotic communication will prove to be better than traditional communication. Yet, after one decade of research, in most cases chaos communication did not take the place of traditional communication schemes. As far as communication efficiency is concerned, chaotic communication schemes are typically less efficient than their traditional counterpart. Still, the main advantage of chaotic communication schemes is for analogy implementation of secure communication. In traditional communication schemes data has to be digitized before encryption takes place. This is due to the fact that traditional encryption is based on discrete number theory. In this paper we study the performance of differential chaos shift key (DCSK) modulation and we compare it to BPSK modulation, a new application of DCSK modulation is presented (transmission of the image) View full abstract»

    In this paper we present, from an academic perspective, the perceived quality ratings of business and technical communication journals. Through a survey of academic experts, we asked respondents to rate the top overall journals, business communication journals, technical communication journals, and the top journals from a technology perspective. In addition, we asked respondents to list the journals that they read most frequently. We analyzed the results by breaking down the rankings into world regions and academic departments. The top-three overall journals for all regions are Journal of Business and Technical Communication, Journal of Business Communication, and IEEE Transactions on Professional Communication. Importantly, differences by world region and academic department type were found in all these rankings. These results can support researchers worldwide by helping them target their publishing efforts to journals that have the best fit with their business and technical communication discipline, world region, and academic home.

    This paper describes “the model of a hypothetical communication system (new generation)”, a method of modelling new generation communication systems. During the introductory period of new communication systems the basic problem of lack of experience arises. This problem is usually solved by a pilot project. Instead of this, there is another way to receive an overall view of the new communication system. This way is presented through modelling of a communication system using its hypothetical model. The described method is founded on a simple idea. While the signal staff officers are planning the structure of the communication system they have the necessary knowledge of the planned communication system. But we can provide a description of the new generation communication system. The model of the hypothetical communication system is determined by specific system properties, station and device properties. This determination is a model of the hypothetical communication system. To solve any problem, the model of the hypothetical communication system can be used during staff exercises. Skilled signal officers and developers have to co-operate in such exercises. This method is suitable for obtaining solutions of all the matters such as structure of communication systems, transit or access nodes. Several solutions may be supported by simulation, for example by using COMNET III. In the paper, the experience obtained in modelling the hypothetical tactical communication system TAKOM-C developed for the Czech Army is presented View full abstract»

    Since optical mobile communication systems do not radiate radio waves from the mobile terminals, they are expected to be used in environments containing sensitive electronic equipment. However, the placement and direction of the optical receivers must be suitably determined for mobile communication because light has high directivity. In optical mobile communication systems, the communication quality varies with the direction of the mobile terminal. Therefore, we examined the angle over which communication is possible at various measurement points and defined it as the communication angle. The mean opinion score (MOS) was obtained to assess the communication quality using the communication angle as a parameter. In this paper, two situations, walking and sitting down, were regarded as representing the way optical mobile communication systems are actually used. We found that for walking, when the communication angle was over 180 degrees, the MOS was over 3 and over 50% of users could communicate usefully. When a user was sitting down, the communication quality did not depend on the communication angle, but only on whether or not the user could communicate in the direction he/she was facing. Thus, if the communication angle in the service area is over 180 degrees, it is possible to communicate in practical situations, even while walking View full abstract»

    The next century will be characterized by the global communication employing user-friendly digital terminals, with which we can exchange voice, picture and data among both individuals and offices. Already the recent statistics tells us that the data communication is very close to the telephone (voice) communication and that the former will soon surpass the latter largely because of the exponential growth of new services through Internet. The data communication traffic has its distinct features over the conventional telephone traffic such as its bursty nature and the number of terminals not restricted by the real human population (the computers can act as senders and recipients). This changes the future forecast of required demands of information capacity upward. The OITDA report on optical communication road map estimates the 1 Mbps data channel will be used by the majority of users by 2010. Already the 1 Tbps single stretch communication channel is the business issue. To support such growing demands the communication facilities and their components must satisfy the high performance requirements with the low cost of fabrication. The recent trends of device technology supporting massive multiplexing (TDM, WDM and O-TDM) are reviewed. View full abstract»

    There is currently an ongoing debate surrounding what would be the best choice for smart grid communication technology. One of the promising communication technologies for smart grid realization is Powerline Communication (PLC). However, because of its noisy environment and the low capacity of Narrowband Powerline Communication, its viability for smart grid realization is being questioned. To investigate this issue, we studied smart grid communication network requirements. We categorize smart grid data traffic into two general traffic classes including home area network data traffic and distribution automation data traffic. Then using network simulator-2, we simulate powerline communication and a smart grid communication network. To have a better understanding of the viability of powerline communication for smart grid realization, some future smart grid advanced applications are considered. Latency and reliability are considered to be the main smart grid communication network requirements. In this paper, the delay of different traffic classes under different network infrastructures and traffic applications have been calculated. Furthermore, a viable powerline communication network infrastructure for smart grid communication network is proposed. View full abstract»
