Zhi-wen, Wang, Yang, Cheng.  2018.  Bandwidth Allocation Strategy of Networked Control System under Denial-of-Service Attack. 2018 4th Annual International Conference on Network and Information Systems for Computers (ICNISC). :49—55.

In this paper, security of networked control system (NCS) under denial of service (DoS) attack is considered. Different from the existing literatures from the perspective of control systems, this paper considers a novel method of dynamic allocation of network bandwidth for NCS under DoS attack. Firstly, time-constrained DoS attack and its impact on the communication channel of NCS are introduced. Secondly, details for the proposed dynamic bandwidth allocation structure are presented along with an implementation, which is a bandwidth allocation strategy based on error between current state and equilibrium state and available bandwidth. Finally, a numerical example is given to demonstrate the effectiveness of the proposed bandwidth allocation approach.
