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 PECAODV 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.

5 Conclusion

The energy efficient routing protocol of wireless sensor network is studied around the bottleneck problem of network layer energy efficient use of wireless sensor network. First, the current research status and advantages and disadvantages of the existing energy efficient routing algorithms for wireless sensor networks are analyzed. On the basis of existing algorithms, an energy efficient (PECMBCR) routing algorithm based on partial energy level is proposed. The energy efficient routing algorithm based on partial energy level is a trade-off between energy efficiency and energy equilibrium consumption of each node. In order to maximize the efficiency of energy use, part of the problem is to avoid the existing energy efficient routing algorithm. The algorithm also introduces variable factor a, and the adjustment of different a values can make the PECMBCR routing algorithm more suitable for the network under different usage scenarios.

Secondly, based on the PEC-MBCR routing algorithm, the PEC-AODV routing protocol is implemented on the basis of the existing AODV routing protocol. The PECAODV routing protocol can avoid the unbalance of the energy consumption among the nodes in the network, which can be avoided by the original AODV routing protocol. At the same time, the problem of high total network energy consumption which is easily caused by the existing minimum maximum battery pin (MMBCR) routing algorithm is also taken into account.
