Abstract: We present the analysis of virus spread in Wireless Sensor Networks (WSNs) through Susceptible-Infective (SI) epidemic models. We analyse both the traditional SI model and the modified SI model. The traditional SI model does not provide any anti-virus protection for WSNs. The modified SI model can improve the network anti-virus capability without extra hardware effort and signaling overhead. We derive the explicit solutions for the epidemic models. Based on the modified SI model, we propose two adaptive network protection schemes for securing WSNs against virus attacks. Numerical results and simulations are provided for further understanding of the analysis.

Keywords: WSNs; wireless sensor networks; epidemic models; virus spread; infective node; network failure; adaptive network protection; network security; anti-virus protection; virus attacks.
