Sensors play an important role in the era of technology these days. Sensors are used everywhere to capture information owing to the environment in which they are used. The group of sensors communicating via a wireless medium to facilitate process of communication for knowledge transfer is termed as wireless sensor networks. In some of the cases the information captured by these sensors may be very critical and needed to be secured. So security in the field of wireless sensor networks is a hot topic of research. The other main reason is because of wireless medium of communication and limited network lifetime because of limited battery life of sensors. Wireless sensor networks consist of large number of sensor nodes. Some of the sensor is stationary and some may be mobile. So, various algorithms have been proposed for security of these networks. To efficiently manage security nodes are grouped together to form clusters. Several clustering algorithms have been proposed. But the main problem is key distribution for the nodes in cluster and key redistribution. Whenever any node leaves or joins the network keys need to be redistributed. So this key management and redistribution overhead is a major issue. So in this paper region based clustering and key management algorithm is proposed for wireless sensor networks.
