Recovery Algorithm: A Network Robustness Enhancement Algorithm Against Malicious Attacks

It is crucial to improve the robustness of the IoT against malicious attacks. For scenarios where the network topology is split due to malicious attacks, but can still reconnect fragmented networks by adjusting links between nodes, existing algorithms offer limited robustness improvements, exhibit high computational complexity, incur significant energy consumption, and produce optimized network topologies lacking scalability. To address these issues, we propose a network robustness optimization algorithm called the ’Recovery Algorithm’. Based on this algorithm, the IoT can automatically adjust its topology to effectively resist malicious attacks. Compared with other algorithms, the optimized network of this algorithm possesses higher robustness and higher communication efficiency without affecting the scalability of the original network. Furthermore, the computational complexity and energy consumption of this algorithm are several orders of magnitude lower than existing algorithms.
