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