无线传感器网络中的病毒传播动力学研究

Analysis of Spreading Dynamics of Virus in Wireless Sensor Networks

从无线传感器网络的基本特征出发,结合传感器病毒感染过程的具体特点,对无线传感器网络上的病毒传播动力学进行研究。分别使用均匀随机分布、簇分布、二维高斯分布、随机格状分布方法来建立平面无线传感器网络模型;结合传染病理论,考虑了无线传感器网络的传播特征以及不同的MAC机制对传感器网络中病毒传播的影响,建立了无线传感网中病毒传播模型。仿真实验表明,有局部聚集的节点散布方式会加快病毒的传播,而采用休眠唤醒机制的通信方式能够限制病毒传播的速度,降低病毒在传感器网络中快速扩散的风险。

The spreading dynamics of wireless sensor networks （WSN） was analyzed by considering the basic charac- teristics of WSN and the characteristics of sensor virus infection process. The different WSN models were established by employing different sensor deployment patterns, which include uniform random deployment, clustered deployment, group Gaussian deployment and random grid deployment. A virus spreading model was established based on infectious disease theory by considering the propagation characteristics of WSN and the impact of different MAC mechanism on virus spreading in WSN. The simulations show that the local group node deployment pattern would speed up the sprea- ding of virus in WSN, while the sleep/wake up communication mechanism would slow down the spreading of virus, re- duce the risk of the virus rapidly spreading in WSN.
