Wireless Sensor Networks (WSNs) has very foremost role with all sensing applications, and also have a wide range of easily deployable applications under any circumstances. That's why it is gaining more attention of researchers every day. WSN is resource constraint type of network, without having battery recharging facility. Routing or path finding for data transfer is the main energy consuming operation of sensor networks, a good number of routing and Mac-Layer protocols has been already designed to enhance its energy efficiency. We try to propose a new Position Responsive Routing Protocol (PRRP) by using Global Positioning Systems (GPS) approach for enhancing energy efficiency of wireless sensor network, under certain controlled conditions. Our research discusses various existing WSN routing protocols and propose a new routing protocol with Position Responsive (PR) approach. Research results shows a 23 to 25 significant improvement in overall efficiency of WSN. © 2011 Global IT Research Inst.
