Topology Optimization Based on Small-world Model in Wireless Sensor Networks
基于小世界模型的WSN簇间拓扑优化方法

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.
