| 摘 要： | 针对无线传感器网络节点因能量消耗、硬件故障、通信因素等导致的链路失效问题,提出一种基于复杂网络小世界模型Kleinberg的无线传感器网络簇间拓扑优化方法,该方法依据簇头节点的局部视图ViewList信息中的长链与短链构建WSN簇间拓扑.实验分析表明,利用该方法演化的无线传感器网络拓扑在节点失效概率为0.2时,网络寿命比DECDC提高25%,并具有良好的能量均衡性和较低的消耗代价.该方法构建的拓扑具有较好的容错性和较强的鲁棒性.

| Abstract: | According to wireless sensor network nodes energy consumption, hardware failure and communication factors lead to link failure,an evolving network method based on complex network theory of small-world Kleinberg model was proposed,which uses long chains and short chains in partial view information to build inter-cluster topology in wireless sensor network. Theoretical analysis and simulations show that the network lifetime is longer 25% than DECDC in the WSN topology which uses this method when the node failure probability is 0. 2 and it has a good balance of energy consumption and lower cost. Thus the topology which uses the method to build has fault tolerant and good robustness. |
