Abstract
En 中文
This paper concentrates on the finite-time clock synchronization problem for wireless sensor networks (WSNs) under deception attacks. Compared with adding additional communication links to a network, we introduce a new mechanism termed as trusted link to improve the resilience of the network, and show that with small changes (set a fraction of links as the trusted links) in the network structure the network robustness for deception attacks can be improved significantly. Then, an iterative learning control based consensus control methodology with built-in attack mitigation mechanism is proposed. Not only the security and robustness are guaranteed by the proposed controller, but also the convergence time is fixed, which makes the synchronization algorithm more suitable for practical WSNs. Finally, simulation results are provided to demonstrate the effectiveness of the theoretical results.
