Survey on Wireless Sensor Routing Protocols

Abhishek Kumar Pandey, Samir Srivastava

Abstract: Wireless sensor networks is a group of sensor nodes which works jointly to perform a common application, it consists of low cost, low power, small in size and multi functional sensor nodes. They are densely deployed in the field. Because sensors are operated by battery power life time of the wireless nodes are limited. So we need some efficient routing techniques by which we can save the life time of the senor node. In this paper we discuss the different types of routing protocol. Routing protocols are application dependent based on the network structure we can classify the routing techniques in three categories data centric, hierarchical and location base. This survey paper is a base paper to understand WSN routing techniques its merits and demerits so one can easily identify routing protocol for specific application.
