Abstract: Recent developments in the field of Wireless Communication and Electronics have enabled the growth in application of Wireless sensor network such as health, military etc. Wireless Sensor Networks comprise of large number of sensor nodes which are tiny and low cost. Sensor nodes have dual functionality of being both data originator and router. It communicate together by various wireless strategies which are regulated by routing protocols. The efficiency of sensor network depend on the routing protocol. In wireless sensor network, routing protocol have three main categories 1) Flat routing 2) cluster based routing 3) Location based routing. This paper shows the survey on cluster based routing protocol in wireless sensor network. In this paper, we focus on the classification of cluster based routing protocol. Finally, we conclude the paper with some future direction.
