-In this communication era, wireless sensor network places a vital role. Wireless sensor network comprises of various types of sensor networks. Deployment of sensor nodes in wireless sensor network is a major concern to optimal result. There are various techniques in deploying the wireless sensor node. Among those some of the methods are, randomized method of deployment, grid based deployment, contour based deployment and projection based deployment. In this paper we are comparing all above methods and we show that projection based method out performs the rest of all othermethods.
