DoS Attack Schedules for Remote State Estimation in CPSs with Two-Hop Relay Networks Under Round-Robin Protocol

Dear Editor, This letter investigates the optimal denial-of-service (DoS) attack scheduling targeting state estimation in cyber-Physical systems (CPSs) with the two-hop multi-channel network. CPSs are designed to achieve efficient, secure and adaptive operation by embedding intelligent and autonomous decision-making capabilities in the physical world. As a key component of the CPSs, the wireless network is vulnerable to various malicious attacks due to its openness [1]. DoS attack is one of the most common attacks, characterized of simple execution and significant destructiveness [2]. To mitigate the economic losses and environmental damage caused by DoS attacks, it is crucial to model and investigate data transmissions in CPSs.
