Abstract: With the rapid network development, static-mobile networks have recently attracted much attention. To solve the problem of cascading failures in the static-mobile network, a cascading failures model is proposed based on mobile overload attacks. In this model, we use a Gaussian Markov model to generate the trajectories of the mobile nodes and define their load using the adjustable parameter β. Cascading failures are caused by mobile nodes attacking static nodes. Based on this triggering mechanism, we develop three different attack modes (i.e., high-degree overload attacks, low-degree overload attacks, and all overload attacks) in scale-free networks. The results show that: multiple processes of cascading failures occur at several different moments; reducing both the number and load of mobile nodes can increase the robustness of the network; among the three attack modes, the low-degree overload attacks cause the most significant scale of failure, followed by the high-degree overload attacks and finally all overload attacks. The experimental results can provide theoretical guidance for cascading failures in static-mobile networks.
