Building Portable Middleware Services for Heterogeneous Cyber-Physical Systems
Software development in wireless sensor networks has traditionally focused on stand-alone applications statically linked with the operating system code, and relying on fixed models for scheduling, synchronization, and resource allocation. Middleware services and network protocols, are usually considered to be part of the operating system. As the number of available WSN platforms and operating systems grows, and the emergence of cyber-physical systems results in the creation of networks of heterogeneous devices (sensor nodes, microcontrollers, mobile devices, etc.), portability and interoperation emerge as major considerations in the software development process.
