A Saving Energy Routing Protocol in WSN Network

Currently, energy-efficient routing protocol is a research hot topic in WSN networks due to the limited energy from the battery. In this paper, a saving energy model is proposed to guarantee minimal the energy consumption of the entire chosen path and prolong the respective node lifetime of entire path utilizing minimal power consumption of each node and extend the whole wireless network lifetime. Based on this novel saving energy model, the effect to normal channel is reduced from the energy consumption and network partition. An approximation algorithm is presented for solving this energy model considering the NPC problem about this novel energy model. Extensive simulation reveals that the proposed EA_AODV protocol is superior to the traditional AODV protocol from the perspective of saving energy and prolonging network lifework, the EA_AODV protocol validity is also verified by related simulation in this paper.
