Wireless Sensor Network (WSN) is type of network which consists of collection of tiny device called sensors nodes. Sensor node has a resource constraint (i.e. battery power, storage and communication capability). To form network, these sensor nodes are set with radio interface by which they are communicated with one to another. The ongoing improvement in sensor technology has made possible WSN that have wide and varied application. While choosing the right sensor for an application a number of characteristics are important. This paper is to present a compressive review of the recent literature on various aspects of WSN.
