Enhancing Energy Efficiency Of Wireless Sensor Network Using Position Responsive Routing Protocol (PRRP) Approach

ABSTRACT

Wireless Sensor Network (WSN) is considered to be a highly resource constrained class of network where energy consumption has being a major challenge. In this work, a cross layer design methodology was adopted to design an energy efficient routing protocol called “Position Responsive Routing Protocol” (PRRP). Position Responsive Routing Protocol is designed to minimize energy consumption of the network by reducing the average communication distance over the network, through information obtained from global position system (GPS) to provide the exact location of the Nodes. The performance of the proposed Position Responsive Routing Protocol was critically evaluated in terms of average energy consumption of the network is 9.8kw with PRRP and 12.7kw without PRRP, which represents energy saving of about 23%. Network congestion of the network is 0.68 over 1.89 without PRRP, BER 2.8 x 10-5 and 7.8 x 10-5 without PRRP also SNR is 7.19 with PRRP and 0.9856 without PRRP. The simulated results show a significant improvement in the WSN in terms of energy efficiency and overall performance of WSN.
