Software Support for Application Development in Wireless Sensor Networks

Developing software for Wireless sensor networks (WSNs) is difficult because they consist of tiny, fragile, and resource-deprived embedded devices that communicate over low-bandwidth wireless links. Middleware can simplify WSN programming; many middleware packages have been proposed. This chapter provides an overview of WSN middleware. It starts with middleware providing basic building blocks, and then focuses on middleware for mobility in all of its forms: data, entity, user, and code. The chapter ends with a discussion on emerging WSN middleware
