Wireless sensor Networks (WSN) are supposed for watching associate environment by sensing it, then collecting information,processing it and eventually transmitting information to final destination. These sensor hubs have a few requirements in view of their confined vitality, stockpiling ability and figuring power. Data is directed from one hub to various utilizing diverse steering conventions. There is assortment of steering conventions for remote sensor systems, where the vitality controlled by a hub is prohibited and visit correspondence between hubs may make the hubs exhaust their vitality assets rapidly. Therefore, we need appropriate routing protocols. Routing protocols are responsible of discovering and maintaining the routes within the network. This paper presents a parametric review of GPSR with routing protocols projected for wireless sensor networks.
