ABSTRACT

Malware is currently one of the main threats to wireless sensor networks. A wireless sensor network becomes unstable due to the presence of malicious signals. Therefore, for controlling malware propagation in wireless sensor networks, a mathematical model is developed which proposes the vaccinating of nodes in the networks. The epidemic model, namely, e-SQIQ1R (electronic-susceptible, pre-quarantine, infectious, quarantine, recovered) has been introduced to restrict the spread of malicious signals in wireless networks. basic reproduction numbers R 0 and 1 have been derived. Here, we compare R 0 and 2. The equilibrium, local as well as global stability of the models, has also been derived. The value of basic reproduction number decides the stability of the network. If this value is less than unity, the network system is free from malware; otherwise, it exists in an infected state. The systems of equations are solved by numerical methods, and MATLAB is used to produce computer models of the system of equations so as to see the dynamic nature of the models. Also, the effect of some influential parameters of wireless sensor networks is properly executed to remove the disturbances from the network.
