为了避免无线mesh网络中的能量空洞问题,提出了簇头节点非均匀分布策略,构建了能耗效率优化均衡路由算法。当无线mesh网络中簇头节点的分布满足一定关系时,该网络能实现最优化能耗效率均衡。从理论上证明了能耗效率优化模型的收敛性,推导出了优化能耗效率均衡约束条件,构建了能量空洞系统规避模型,为无线mesh网络的长久可靠运行提供理论依据。仿真实验结果表明,该策略模型能有效缓解无线mesh网络中存在的能量空洞问题,延长该网络的生存周期和降低网络剩余能量率。

In order to avoid the energy hole problem in wireless mesh network, the non-uniform distribution strategy about the cluster nodes was put forward, the energy efficiency optimization equilibrium routing algorithm was designed. When the distribution of cluster nodes in the wireless mesh network met the certain relations, the network could optimize the energy consumption efficiency equilibrium. In order to provide the theory basis for reliable operation in wireless mesh network for a long time, the convergence of efficiency optimization model was theoretically proved, the constraint condition of optimizing the energy consumption efficiency equilibrium was derived, and the energy hole system avoidance model was built. The simulation results show that using this strategy can effectively relieve the energy hole problem in wireless mesh network, prolong the network life cycle and cut down the network residual energy rate.
