“小世界”理论在无线传感器网络的研究现状

Survey on "Small world" theory in wireless sensor networks

"小世界"现象的普遍性及平均路径长度小和集聚系数大的特点,使其在无线传感器网络中的应用越来越广泛。本文在对"小世界"理论的研究背景、网络模型、网络主要特征度量及"小世界"特性进行介绍后,重点分析了"小世界"理论在无线传感器网络的研究现状及其今后的发展趋势。

'Small world' phenomenon of the universality and the characteristics of small average path length and large clustering coefficient make it to be applied in wireless sensor network more and more widely. This paper introduces the 'small world' theory of research background,network model,the main characteristics of network measurement and the 'small world' properties as well. Then we focus on the current research status and the future trends of 'small world' theory in the wireless sensor network.
