A Survey on Middleware Challenges and Approaches for Wireless Sensor Networks

Wireless sensor networks (WSN) are used in many applications like environmental monitoring, infrastructure security, healthcare applications, and traffic control. The design issue of such applications must address related to challenges around WSN Characteristics on one hand and the applications on the other. Middleware is a software that provides a common platform for the heterogeneity in WSN, enabling multiple applications to work parallel on a distributed network. This paper surveys the work state of research in middleware design, development and general issues in designing a middleware for WSN. It also examines the various approaches of middleware design, the trends and challenges to be addressed when designing and developing these solutions for WSN.
