摘　　要：本文分析了小世界理论和无线传感器网络建模过程中的关键技术,为了提高网络的生存周期,将小世界理论与无线传感器网络拓扑控制融合,提出一种拓扑控制算法。该算法旨在利用小世界理论的长程链接,将长程链接引入传感器网络,减少网络收发信息的能耗,并与层次型拓扑控制算法进行仿真比较。实验数据证明,该算法能在一定程度上改善网络的生存周期。This paper analyzes key technologies in the small-world theory and modeling for wireless sensor networks. In order to improve the lifetime of the network, by integrating the small world theory with wireless sensor network topology control, the paper proposes a topology control algorithm which is designed to take the advantage of long-range links in the small-world theory. By introducing the long-range links into the sensor network, we can reduce the energy consumption of the network while sending and receiving information. When compared with the hierarchical topology control algorithm simulation, experiment results can effectively validate that the algorithm can improve the lifetime of the network to some extent.
