Abstract
In order to improve the power supply problem of network nodes, the energy efficient routing algorithm of wireless sensor network is studied and improved. A new energy efficient routing algorithm and protocol is proposed to prolong the lifetime of the network. First, the energy efficient (3PEC-MBCR) routing algorithm based on partial energy level is proposed in this paper. Secondly, according to the PEC-AODV routing protocol, the energy consumption of the network and the balance of energy consumption of each node are taken into account, so as to prolong the network lifetime. Finally, the PEC-AODV protocol module is added to the NS-2 simulation platform, and the simulation and performance evaluation of the PEC-AODV protocol are made by NS-2. The simulation results show that the algorithm not only reduces the total energy consumption of the network, but also balances the energy consumption between nodes, which maximizes the lifetime of each node. It is concluded that the PEC-AODV routing protocol is more effective in energy utilization than the existing AODV routing protocol or other energy-efficient routing protocols, which results in a certain role in prolonging the lifetime of the entire network.
