基于旋转有向天线的无线传感器网络恶意软件传播模型

Malware Propagation Model for Wireless Sensor Network Based on Rotating Directional Antenna

在无线传感器中使用有向天线进行信息传输,从恶意软件传播视角出发,建立基于旋转有向天线的SEIRS恶意软件传播模型,利用微分动力学系统研究无线传感器网络中的恶意软件传播行为。研究结果表明,当恶意软件基本再生数R_0小于等于1时,会消除网络中的恶意软件,系统全局渐进稳定在无病平衡点。当R_0大于1时,网络中恶意软件会持续存在,系统全局渐进稳定在地方病平衡点。最大通信半径、方向角大小和旋转角速度的阈值分析结果验证了理论的正确性。

For a Wireless Sensor Network （WSN） using directional antennas for information transmission, a SEIRS malware propogation model based on rotating the directional antennas is established. Differential dynamic system is used to study the behavior of malware propogation in WSN. The results show that when the basic reproductive number of malware,R0,is less than or equal to 1, malware in network eventually eliminates and the disease-free equilibrium of system is globally asymptotically stable. When R0 is greater than 1, malware in network exists continually, and the endemic equilibrium of system is globally asymptotically stable. Analysis on the thresholds of the maximum communication radius,direction angle and retational angular velocity verifies the correctness of the theory,
