Mobility increases the risk of malware propagations in wireless networks

In this paper, we study the malware propagation issue in wireless networks, considering the features of channel interference, access competition and possible mobility. We propose a basic spread model based on the uniform scanning strategy. Referring to the wireless transmission and network capacity theories, we provide the bound of infection rate in wireless networks with fixed nodes. Furthermore, we evaluate the impact of mobility on malware propagations. Detailed performance analysis shows that mobility will greatly increase the risk of malware attacks in wireless networks. The results in this paper provide insights on the malware propagation characteristics in wireless networks and fundamental guidelines on designing defence schemes.
