Abstract:- Wireless sensor network is a network formed by large number of sensor nodes which are randomly distributed in some regions. There is an issue of limited power supply of node and in fact battery of node is infeasible in replacement. The Life time of wireless sensor network is very much dependent on the life of each sensor node. As node does the task of sensing and forwarding the data to sink, this data forwarding has to be efficient to efficiently utilize the battery power of sensor node. Various researches have been done in finding the efficient routing scheme to efficiently route the data from sensor node to sink by aiming the minimization of the energy consumption of sensor nodes. In this paper we have surveyed and discussed the various routing protocols that aim to increase the life time of network.
