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.
