Performance Analysis of Hierarchical Routing Protocols of Wireless Sensor Network: A Survey

Abstract: Wireless sensor network (WSN) consists of small sensor nodes with sensing, computation and wireless communication capabilities. In this paper we discuss the important hierarchical routing protocols for Wireless Sensor Networks. We will discuss the operations of the protocols and advantages and disadvantages of these hierarchical routing protocols. The main issue of the wireless sensor network is energy consumption because there is limited battery power. If the battery goes down, then the sensor nodes die quickly. So to solve this problem there is come so many routing protocols which are used for solving this problem. There are a lot hierarchical routing protocols like LEACH, TEEN and PEGASIS.
