Abstract:
A SIR/WS model of malware propagation in Wireless Sensor Network(WSN) is proposed after the model of WSN is obtained. Based on IEEE 802.15.4 and epidemic theories, the model considers the mechanism of saving energy and describes the broadcasting process of malware in the WSN. It is found that the propagation of malware in the WSN can be restrained by increasing the recovery rate and decreasing the infection rate. Simulation results show that the model works well.

摘要： 由复杂网络理论得出一种无线传感器网络的模型，结合IEEE 802.15.4标准及流行病学理论，综合考虑目前传感器网络通过节点休眠与唤醒机制来节约能耗，提出一种无线传感器网络中恶意程序传播的SIR/WS模型。该模型描述了感染节点以广播方式传播恶意程序的过程，发现提高免疫率及降低传染率均可抑制恶意程序在无线传感器网络中的传播。仿真结果表明，该模型能较好地描述无线传感器网络中恶意程序的传播特性。
