摘　　要：该文首先介绍了小世界(Small-W orld)现象的起源、发展现状及在现实中的应用。随后介绍了一种基于证书链的Adhoc网络的信任模型。然后根据Ad hoc网络拓扑结构确定性理论,为了在Ad hoc网络中实现“Small-W orld”现象,使得网络中任意节点之间的信息传输中所经历的中间节点尽可能少,从而节约Ad hoc网络中存在的信息传输对节点计算和电力等资源的不必要的消耗。基于上述理论及对现实应用的考虑,该文建立了一个模型,并在NS-2上进行了仿真实验,最后对该模型的安全性方面进行了一些讨论。In this paper we firstly introduce the“Small- World” phenomenon and its application in real- world. Then we present a new kind of trust model in Ad hoc network. According to the deterministic topological theory, and in order to apply and realize the “Small - World” in Ad hoc network whose target is to reduce the number of relay nodes thus saving much of the communication and power resource, we put forward our model and test it on the NS - 2 network simulator. And at last, we discuss the model briefly.
