Energy Efficient Mobile Wireless Sensor Network Routing Protocol

Mobility in tandem with energy efficiency in wireless sensor network endows with significant challenges for routing. Sensor nodes have limited energy supply and minimizing the power consumption is crucial in Mobile Wireless Sensor Network (MWSN). This paper proposes a novel hybrid multipath energy aware routing protocol for MWSN called Energy Efficient Mobile Wireless Sensor Network Routing Protocol (E2MWSNRP). The Energy Aware (EA) selection mechanism and the Maximal Nodal Surplus Energy estimation technique employed in this algorithm improve its energy performance. The ‘readiness’ concept of EA selection prolongs the network lifetime. The hybrid routing concept applied in this algorithm presents the advantages of both the reactive and proactive routing. An evaluation methodology and simulation environment to verify the operation of this algorithm is presented here. Simulation results can demonstrate that the proposed scheme can outperform the existing routing protocols in terms of energy efficiency, network lifetime and packet delivery ratio.
