一种新的无线传感器网络危害传播模型

A Novel Model of Node Compromise Spreading in Wireless Sensor Networks

研究了无线传感器网络中的危害传播问题,提出了一种新的危害传播模型。针对随机图模型存在的不足,利用随机几何图来构造无线传感器网络的拓扑,分析无线传感器网络中的危害传播,并与随机图构造的网络拓扑下的危害传播进行比较。结果表明,采用随机几何图拓扑网络比随机图拓扑网络能够更有效地减缓整个网络的危害爆发。

In this paper, a novel model of node compromise spreading is proposed to investigate the threat of node compromise spreading in wireless sensor networks. To overcome the disadvantages of random graph model, we investigate node compromise spreading in random geometric graph model constructed according to the parameters of the networks ,and compare the proposed random geometric graph model with the random graph model. It shows that the compromise spreading in the network constructed by random geometric graph model is slower than that by random graph model.
