A predator–prey model on the attacking behavior of malicious objects in wireless nanosensor networks

Abstract

In this paper, we envision attacks of malicious objects and their transmission in wireless nanosensor networks (WNSNs) with the help of a predator–prey model. Here the prey consists of susceptible nanosensor nodes, susceptible nanosensor nodes with vaccination and infectious nanosensor nodes, whereas the predator consists of terminally infected nanosensor nodes. The dynamics of the system is analyzed at different equilibrium points to find the conditions for their stability. Impact of vaccination on the overall system is also analyzed. Extensive numerical simulation is performed to validate the vitality of the model developed. In short, the goal of this model is to determine whether WNSNs are able to survive against attacks of malicious objects or not and can vaccination play a key role in it.
