Energy distribution to get more lifetime and noninterfering multipath are two major challenges in Wireless Multimedia Sensor Networks (WMSNs) routing. The Greedy Perimeter Stateless Routing (GPSR) is a simple routing protocol which uses minimum geographic distance to forward packets toward sink node. However it does not consider energy level and uses single path. Geographic energy-aware non-interfering multipath Routing (GEAM) overcomes this problem by multipath routing and energy consideration, but keeping state of the multiple non-interfering areas has an overhead. In our proposed routing protocol which is called Energy Aware Greedy Stateless Geographic Routing (EAGSGR) we will introduce two path routing without interference only by using two strategic areas. We meanwhile introduce a simple way to deal with the dead end nodes and clusters problem. EAGSGR showed a better performance compared to GPSR and GEAM in terms of QoS parameters such as end-to-end delay, average hop count, energy distribution and packet delivery ratio.
