Study of Different Routing Protocols in Wireless Sensor Networks

Wireless sensor networks consist of small nodes with sensing, computation, and wireless communications capabilities.Routing as one key technologies of wireless sensor network has now become a hot research because the applications of WSN is everywhere, it is impossible that there is a routing protocol suitable for all applications. Routing protocols in WSNs are also application specific which has led to the development of a variety of protocols. In this paper, we give a brief survey of different routing algorithms for Wireless Sensor Network and compare their strengths and limitations. Each routing protocol is described and discussed under the appropriate category. The paper concludes with issues open for research.
