A wide range of high-performance distributed embedded systems have been designed and deployed. Physically distributed embedded systems are used for manufacturing and control, traffic analysis, and other problems. Interestingly, today's systems-on-chips are sufficiently complex that they must be treated as distributed embedded systems. At all scales of physical extent, middleware is required to manage...
Embedded systems is an area that grows rapidly with new communication media such as smart-phones, house automation applications (that might finally come) and all other hidden systems we use everyday in cars, airplanes, etc. Moreover, in these last domains, there is a need for very safe development because such systems are often life-critical.
Although a growing number of devices have the support for parallel processing, parallelism is not widely exploited, as it should be. This can be illustrated by the fact that all Apple desktops and laptops are currently supplied with one or more dual- core processors. Despite this, parallel programming in popular languages such as Java is not widely encouraged and often only recommended as a last resort...
Recent advances in software processes and artifacts for automating middleware configurations in distributed realtime and embedded (DRE) systems are starting to address the complexities faced by system developers in dealing with the flexibility and configurability provided by contemporary middleware. Despite the benefits of these new processes, there remain significant challenges in verifying their...
In an integration system of RFID and wireless sensor network (WSN), RFID is used to identify objects while WSN can provide context environment information of these objects. Thus, it increases system intelligent in pervasive computing. We propose the EPC sensor network (ESN) architecture as an integration system of RFID and WSN. This ESN architecture is based on EPCglobal architecture, the de facto...
Grid computing has emerged as a new paradigm of distributed computing technology on large-scale resource sharing and coordinated problem solving. Based on a proposed Web service-based grid architecture, we have designed a service grid middleware system called CROWN which aims to promote the utilization of valuable resources and cooperation of researchers nationwide and world-wide. To address the issues...
Universal middleware bridge (UMB) provides seamless interoperation among heterogeneous home network middleware. There have been high demands for the UMB components (UMB core and adaptors) to have fault- tolerance capabilities. This paper presents a TMO structuring approach together with new implementation techniques for the fault-tolerant TMO-replica structuring scheme called PSTR. PSTR implementations...
Building middleware for distributed applications is a complex task, mixing antagonistic concerns: heterogeneity, performance, reliability, quality of services. Optimization and fine-tuning of middleware for a particular application is even a harder task, usually done manually or through complex design patterns. The advent of "schizophrenic" middleware which separates concerns between distribution...
Effective resource management for distributed real-time embedded (DRE) systems is hard due to their unique characteristics, including (1) constraints in multiple resources and (2) highly fluctuating resource availability and input workload. DRE systems can benefit from a middleware framework that enables adaptive resource management algorithms to ensure application QoS requirements are met. This paper...
This article represents our concept of an artificial hormone system for realizing a completely decentralized self-organizing task allocation using self-X properties. We present new evaluation results from our latest research: we introduce a tool to easily create test files and even whole test series, and show several test series that illustrate interesting behaviors of hormone interaction with different...

In this paper, we propose a method to verify software executed on RTOS which conforms to mulTRON with a model checking tool Spin. The RTOS provides facilities such as priorities and service calls to control the execution of tasks, however, Spin does not provide them. Thus, we implemented a middleware which allows us to use the facilities and simulate the execution of the tasks in Spin. The paper shows...
