Model-based QoS evaluation for embedded wireless sensor networks

Wireless sensor network technologies can be used for industrial embedded system design to save cabling cost and weight. However, their environment, architecture, and design issues are quite different from original sensor network applications. Simulation tools and system design environments have to be adapted to the special requirements, such as operational modes and phases which influence the system. This paper presents a more detailed wireless sensor network to check against the application requirements concerning QoS, reliability, and lifetime. An avionics application example is presented.
