Abstract: The layered network model and MP-EA(multi-path routing protocols with energy-aware protocol) of WSNs(wireless sensor networks) are studied.In order to overcome the drawbacks of existing protocols,the IMP-EA(improved multi-path routing protocol with energy-aware protocol) is presented.Taking network life and packet drop rate as the performance matrix,the simulation performance of IMP-EA is analyzed and compared with other three routing protocols.Simulation results show that IMP-EA can prolong the network life effectively and enhance the data transmission efficiency.
