Context Aware Computing in Wireless Sensor Networks

Wireless sensor networks offer significant improvement over traditional sensor networks. Wireless sensor network (WSNs) consists of small sensor nodes, which are capable of sensing, processing and wireless communication capabilities. Recently Context-aware computing is an area of interest in WSNs. Context aware computing (CAC) is a paradigm in which applications make use of contextual information such as time, people, location and activity. The CAC is a rich area of research. In this paper we have looked into the CAC, types of contexts, context-aware models and some of the applications based on the CAC in WSNs.
