Efficient Position Based Packet Forwarding Protocol for Wireless Sensor Networks

In Wireless Sensor Networks, sensor nodes are controlled by either base station or without bases station. In our scheme, the sensor nodes are not depends on the base station. Once the sensor node sent a packet to the destination node, the residual energy is calculated through the multipath routing approach. In this research work, an Efficient Position based Packet Forwarding Protocol (EPPFP) to increase packet delivery rate based on the position of sensor nodes. It consists of three phases. In first phase, multipath routing is implemented based on link with high packet forwarding capacity. In second phase, packet forwarding scheme is implemented to achieve high packet delivery rate and to schedule the packet transmissions to multiple packet forwarders. In third phase, packet forwarding verification is proposed to verify whether or not packets are successfully forwarded. Based on simulation results, the proposed EPPFP achieves high delivery ratio, increased network lifetime, less delay, minimum overhead and energy consumption in terms of mobility, time and number of nodes than existing schemes namely.
