The popularity of wireless sensor networks is increasing tremendously day by day due to the vast potential of sensor networks to provide many applications such as military applications, health monitoring, environmental monitoring, etc. For the different application areas there are different technical issues that the researchers are resolving. Wireless sensor networks consists of small low cost sensor nodes, having a limited transmission range and their processing, storage capabilities and energy resources are limited. This network gathers the information from nodes and transmits to base station for further processing. To perform routing in wireless sensor network with this limitation of low power, energy and storage capabilities is a major problem.
