    The diversity of the applications supported by wireless ad hoc and sensor networks explain the success of these networks. However, their energy constrained nature requires the use of energy efficient strategies to maximize network lifetime. We can classify these strategies in four categories: 1. energy efficient routing, 2. scheduling the nodes sleeping state, 3. topology control by tuning node tr... View full abstract»

    A wireless sensor network consists of a large quantity of small, low-cost sensor nodes that are limited in terms of memory, available energy and processing capacity. Generally, these sensor nodes are distributed in space to obtain physical parameters such as temperature, humidity, vibration or light conditions, and transmit the measured values to a central entity. The measurements are tagged with ... View full abstract»

    Personal healthcare is a promising market of a personal area network (PAN). The PAN consists of a data collector and multiple wearable sensors which must send data to the collector according to the frequency specified by each PAN. The data collector may be any hand-held or portable device, e.g., a mobile phone, a PDA, or a wristwatch. An individual user needs a PAN in order to detect, track, or ma... View full abstract»

    Several factors greatly influence the quality of service (QoS) in multihop wireless mesh networks (WMNs). These include the transmission range, number of gateways, number of nodes served by each gateway, gateway location, relay load and access fairness. While finding an optimal solution to simultaneously satisfy the above constraints is known to be MV-hard, near optimal solutions can be found with... View full abstract»

  • Applying Distributed Classification Algorithms to Wireless Sensor Networks – A Brief View into the Application of the SPRINT Algorithm Family

    Publication Year: 2008, Page(s):52 - 59
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (262 KB) | HTML iconHTML

    The SPRINT algorithm describes a distributed way to construct a decision tree for classification in large data sets. It can be applied to in-network classification tree construction. The costly data transfer of sensor data to the sink can be avoided while execution time is still acceptable. The SPRINT algorithm and its extensions are introduced. Furthermore, different scenarios that implement clas... View full abstract»

    An efficient and scalable multicast routing protocol for ad hoc networks is proposed. Network Sender Multicast Routing Protocol (NSMRP) is a mesh based protocol. A central node called mesh sender (MS) is selected periodically from among the group(s) sender(s) to create one mesh in order to be used in forwarding control and data packets to all multicast group(s) member(s). One invitation message wi... View full abstract»

  • QoS as Means of Providing WSNs Security

    Wireless sensor networks are increasingly being used in applications where QoS and low cost are the overriding considerations. Conventional schemes of using sensor nodes and incorporating these three phenomena (reliability, availability and serviceability) to attain QoS can effectively improve not only the reliability of the overall WSNs but security as well. We discuss the reverse look of QoS and... View full abstract»

    The performance of a TCP connection is typically dictated by what the network can provide rather than what the application would like to achieve. In particular, the additive-increase multiplicative-decrease (AIMD) mechanism employed by TCP hinges on its ability to meet specific throughput requirements since it has to respond to congestion signals promptly by decreasing its sending rate. The level ... View full abstract»

    In the coming next generation network, the introduction of new services with different quality of service (QoS) requirements combined with cost conscious customers who make cost/utility trade-offs, yields a need for the network operators to be able to offer different levels of guaranteed availability. Protection techniques are used to provide alternative paths to a connection in case of failure of... View full abstract»

    The third generation network which is vigorous nowadays will be followed by an all-IP infrastructure which is referred as NGN (next generation networks) in the near future. The heterogeneity and mobility of the NGN bring many challenges to the charging system in network management. Charging should be more dynamic in an end-to-end session which includes several service components. In this paper, we... View full abstract»

    One of the main quality of service mechanisms, allowing mainly the protection of already active flows, is admission control. This is even truer on the MAC level of 802.11 based networks due to scarce resources. We present in this paper a hybrid admission control algorithm for IEEE 802.11e EDCA. The algorithm uses the synthetic Markov chain model of EDCA that we developed in previous work injecting... View full abstract»

    New collaborative applications relying on a MANET need multicast to perform efficient group communication. Application layer multicast is seen as a good alternative to the traditional network layer routing protocols because of its flexibility and ease of deployment. However, existing application layer multicast protocols for MANETs are not designed for collaborative scenarios. In this paper, we pr... View full abstract»

    For emerging resource-constrained sensor networks, energy efficiency and computation simplicity could be as important as precision. Existing terrestrial synchronization protocols have already achieved high precision in radio networks, but none of them perform well in high latency networks like underwater acoustic sensor networks: they either assume instantaneous packet transmission between nodes, ...
