摘要
针对WSN(Wireless Sensor Net)结构中存在大量的网络覆盖冗余与节点唤醒时间的延长,耗费了资源同样也增加了节点的工作能耗的特点。设计了一个拓扑控制方案,减少网络冗余的同时,兼顾了网络的鲁棒性,并且保证生成拓扑具有最小的能量消耗。该方案根据节点的位置信息,建立各监测节点到簇节点的能量消耗最小并且可以保证K容错的K连通子图,方案中将异构监测WSN作为控制对象,需要简化网络为同构传感器网络,便于简化计算。该研究方案在保证传感器网络节点在K连通下,可以最大限度减少传感器网络中的冗余路径,且可以较好均衡、降低WSN能耗,延长WSN生命周期。
For WSN (Wireless Sensor Net) structure, there are a lot of network covers redundancy and node awaken the extension of time, cost the resources also increases the energy consumption of the characteristics of working node. Design a topology control program, not only reduce the network redundancy, both also give consideration the robustness of the network and ensure the topology generation has the lowest energy consumption. According to the position information of nodes, the program establish the monitoring node to the minimal energy consumption cluster nodes and can ensure K-connected figure of K fault-tolerant, program use heterogeneous monitoring WSN as control object , need to simplify network for isomorphism sensor network and facilitate the simplified calculation. The research programs guarantee sensor nodes connected in K, not only reduces the redundancy path effectively, but also balances and reduces the energy consumption of WSN and prolongs WSN life cycle.
