Cooperative Opportunistic Routing Protocol for Wireless Sensor Networks

Abstract

This paper presents CORP (cooperative opportunistic routing protocol) for WSN (Wireless Sensor Networks), providing robustness to the random variations in network connectivity while ensuring better data's forwarding efficiency in an energy efficient manner. Based on Realistic link layer, we combine the region-based routing, rendezvous scheme, sleep discipline and cooperative communication to model the data's forwarding by cross layer design in WSN. Simulation results show that COPR performs better than Non-cooperative opportunistic routing from perspectives of adaptation of variations in network connectivity and satisfying application QoS requirements.
