By introducing the new concept of dead state of nodes in WSNs and the Susceptible-infectious-recovered-susceptible (SIRS) mechanism of worm propagation, this paper improves the SIR (Susceptible-infectious-recovered) model, and proposes a novel model to analyze the dynamics of worm propagation in Wireless sensor networks (WSNs), called the iSIRS model. The iSIRS model is based on the epidemic theory, consists of a group of differential equations, and it can effectively describe the process of worm propagation with energy consumption of nodes in WSNs. Simulation results demonstrate the validity of the iSIRS model.
