In WSNs routing of data consumes a lot of energy due to excessive flooding of packets. In the proposed EERP scheme routing is done on the basis of intensity of received signals. Unlike REEP, information packet is forwarded by only one source sensor node. The information packets are forwarded by the sensor node which has the maximum intensity of received signal from the object. Alternate routing paths are also maintained through local flooding. Theoretical analysis and simulation results show that the proposed routing protocol is more energy efficient as compared to other existing protocols such as Directed Diffusion and REEP.
