AN ENERGY EFFICIENT COOPERATIVE AND INCREMENTAL RELAY NODE SELECTION BASED ROUTING PROTOCOL FOR WSN

ABSTRACT Abstract- In wireless sensor cooperative networks, the cooperation among the neighboring nodes can significantly improve energy efficiency of a network. In this paper, energy efficient and load balanced cooperative relay selection for wireless sensor networks is proposed. By optimizing the total data transmission time and balanced load among various relay and cooperative nodes, network reliability is improved. It helps to make the network more energy efficient by forming coordination. During analysis of all the existing protocols, find out that protocol in which directly data transmission from Cluster Head to Base station depletes their energy earlier as compared to other ones. So, the proposed protocol equally distributes the load among all nodes. Mainly this approach is best suitable for the homogeneous network, in which all nodes deployed with same energy level, for the densely deployed area and nodes are considered as static. In this, data transmission time is minimized using the relay nodes. By considering the various parameters energy and scalability; Simulation results of proposed protocol shows the remarkable improvement in energy savings over non-cooperative routing LEACH, SEP, Z-SEP.
