Abstract

A wireless sensor network consist of sensor nodes which are capable to perform sensing, computation and transmission. These sensor nodes have limited power which is difficult to replace due to hostile environment. Therefore to increase the lifetime of wireless sensor network, it is required to develop such techniques to consume lesser energy. Wireless sensor network is nowadays being applied in many different civilian applications like vehicle tracking, building and forest and earthquake contemplation, bio-medical or health care applications. Wireless sensor network is built with many sensor nodes. Node deployment is very important task in wireless sensor network. Different approaches are used for the deployment of sensor nodes are: random deployment and deterministic deployment.
