摘要: 将无线传感器网络和无线网状网络相结合构建了无线网状传感器网络拓扑结构,将部分传感器设为休眠状态可以降低高密度无线网状传感器网络中的能量消耗,并且均衡网络能耗可以解决能量空洞问题。提出了一种基于簇首轮替的无线网状传感器网络能耗均衡的休眠调度方案。通过建立簇首轮替的能耗模型,得到在不同传感器轮流担当簇首的条件下网络能耗均衡时传感器的休眠概率。分析和仿真结果表明,相比较随机调度方案,该方案保证了网络覆盖范围,延长了网络生存时间,均衡了网络的能耗。

Abstract: Wireless Mesh Sensor Networks(WMSN) topology structure was constructed by combining Wireless Sensor Networks with Wireless Mesh Networks. Energy consumption in the high-density WMSN could be decreased by putting the partial sensor nodes into sleeping state and the energy holes problem could be solved by balancing the network energy consumption. This paper proposed a balanced-energy sleeping scheduling scheme based on alternating cluster head nodes in WMSN. hhe sleeping probability of sensor nodes in balanced-energy network was obtained by building cluster head alter-nated model when different sensor nodes took turns to be cluster head. Analytical and simulation resups show that the scheme assures the network coverage, extends the lifetime and balances the energy consumption compared with Randomized Scheduling scheme.

Key words: WMSN, Balanced-energy, Alternating cluster-head, Sleep scheduling scheme
