    Weapons System Open Architecture (WSOA) utilizes a distributed object computing foundation as a "bridge" to enable communication between disparate real-time systems in the redirection of strike assets. This open systems "bridge" connects legacy embedded mission systems and off-board C3I (command, control, communication and information) sources and systems. WSOA will establish the potential gains i... View full abstract»

    New applications introducing restrictions in power consumption, heat, costs and available space are leading to small microcontrollers becoming increasingly important in distributed real-time systems. Traditional real-time middleware architectures are insufficient for these small devices. The paper presents an ongoing approach of constructing middleware for small devices by adapting the microkernel... View full abstract»

    A key challenge in keeping distributed clocks well synchronized in a LAN environment via OS-or middleware-level mechanisms is to create an interference-free condition in a network channel(s) and a nonpreemptible on-alert condition in the responsible thread in each node during each resynchronization round while keeping the length of each round as short as possible. An approach for meeting this chal... View full abstract»

    The paper proposes an approach to solve the situation. In our approach, we have developed a middleware component to connect several middleware implementing these object-oriented standard specifications for home computing. Actually, our middleware component makes it possible to connect home appliances adopting HAVi, Jini, or UPnP. Therefore, various home appliances can communicate with each other View full abstract»

    The Unified Modeling Language (UML) has received increasing attention from designers of real-time systems. Several approaches apply and enrich the UML notation for modeling of real-time applications. In addition to that, UML modelers can make use of the Object Constraint Language (OCL) to restrict their models by additional constraints. Currently, OCL and real-time extensions of the UML only provi... View full abstract»

    Monitoring is a widely-used technique to check assumptions about the real-time behavior of a system, debug the code, or enforce the system to react if certain deadlines are passed. Program instrumentation is needed to insert monitoring code fragments into the monitored system if the monitor is implemented without hardware support. This paper describes a language-based approach to automated program... View full abstract»

    Scoped memory is perhaps the most novel contribution of the Real-Time Specification for Java (RTSJ) to the Java programming language. In this paper we show that scoped memory can be used to reduce the processor overhead of any possible garbage collection algorithm and to avoid all latency introduced by any garbage collection algorithm. These semantics make it easier to write correct real-time prog... View full abstract»

    Two recent standards have a great potential to impulse the use of object orientation in the development of real-time applications. The first is the Real-Time Specification for Java (RT-Java), consisting in an application programming interface (API) for real-time object-oriented programming. The other is the emerging RT-UML standard, which addresses the specification of real-time requirements and t... View full abstract»

    Distributed object computing middleware such as CORBA, RMI, and DCOM have gained wide acceptance and has shielded programmers from many tedious and error-prone aspects of distributed programming. In particular, CORBA event service has been used extensively in embedded systems. We propose an aspect oriented approach to develop synchronization code for distributed systems that use event service as t... View full abstract»

    The demand for real-time database services has been increasing. Examples include sensor data fusion, stock trading, decision support, Web information services, and data-intensive smart spaces. In these systems, it is essential to execute transactions in time using fresh (temporally consistent) data. Due to the high service demand, many transactions may miss their deadlines regardless of their impo... View full abstract»

    We present a methodology based on communicating extended finite state machines (CEFSM) to generate tests automatically from system specifications. Unlike other model-based methods, it does not require the creation of any new models. Rather, it uses the existing available system models including both data and behavioral information. Our CEFSM-based test generation uses FSMs (finite state machines) ... View full abstract»

    OCL (Object Constraint Language) is becoming an important means to formulate formal specifications in the context of object-oriented software development. The question is whether this approach is appropriate for real-time systems as well. This question is discussed from the point of view of UML/OCL itself but also from an applications point of view View full abstract»

    Two limitations of the current implementations of adaptive QoS behaviors are complexity associated with inserting them into common application contexts and lack of reusability across applications. What is needed is a way of bundling all the specification for systemic behavior into one place, and making it feasible to insert the collection of related QoS management artifacts into applications as a ...

    A QoS-aware real-time operating system must schedule multiple tasks which have different timing constraints and which access various resources including the CPU, disk and network. These resources, however, are not independent of one another. For example, resources like network bandwidth and disk bandwidth are available on a single node but must be managed by their host OS on the CPU by means of in... View full abstract»

    Component-based infrastructures provide support for the development and execution of component-based systems. However they have limitations in their application in real-time and reliable systems, because they do not integrate facilities to support these types of problems and include limitations of predictability and dependability. These infrastructures are designed to provide support to financial ... View full abstract»

    The recently adopted UML Profile for Scheduling, Performance and Time (a.k.a. the RT Profile), has the potential to standardize terminology and practice within the real-time UML community, but its scope is still very limited; particularly its use in characterizing infrastructures, such as middleware and operating systems. This paper shows how the profile might be used to model the OSEK operating s... View full abstract»

    Modern computer based systems are becoming increasingly complex ensembles of hardware and software; thus adding more challenges to the software requirements engineering process. Although it is well acknowledged in the literature that the use case technique provides a successful requirements engineering tool, there is very little published material on how the use case technique deals with large com...
