Abstract
The characteristics of wireless sensor networks can be programmed over the air interface lead to a serious threat to its security. This paper proposed susceptible - infectious - recovered model of propagation based on two - dimensional cellular automata, which analyzes the characteristics of dynamic propagation in the wireless sensor networks with regional detection mechanism. Numerical simulation analysis shows that regional detection mechanism not only makes the wireless sensor networks regionalization, but also can inhibit the malware propagation in the wireless sensor networks by allowing the sensor to implement detecting strategy, thereby reducing the risk of large-scale outbreak of virus in wireless sensor networks.
