TMSE: A topology modification strategy to enhance the robustness of scale-free wireless sensor networks

摘要: Abstract Scale-free wireless sensor networks (WSNs) are tolerant to random attacks but vulnerable malicious attacks. With the increase of cyber-attacks, improving survivability and robustness is critical scale-free WSNs. This paper introduces a topology evolution mechanism (SFTEM) for WSNs, model considers fault probability nodes as well communication range. Then, new modification strategy enhancing WSNs presented, namely TMSE. Different from previous works, we consider different types attack into algorithm design, making TMSE more resistant realistic Besides, consists two operations, in which high degree operation (HDO) changes network connections among base on being attacked, associativity (DAO) transforms onion-like structure using its degree–degree correlation. Meanwhile, all modified by maintain node degree, thus final preserves properties. Simulation results demonstrate that generated SFTEM has characteristics, can be effectively improved TMSE, compared existing algorithms.
