N2 - Jamming poses a significant threat to wireless communication networks. This paper investigates anti-jamming strategies for a multi-cluster wireless powered communication network (WPCN) aided by multiple reconfigurable intelligent surfaces (RISs). The objective is to maximize the anti-jamming sum throughput by jointly optimizing time and bandwidth allocation, as well as phase shift matrices. To address the nonconvex nature of the original problem, we first derive closed-form solutions for time and bandwidth scheduling. Then, we propose an alternative approach for phase shift optimization, leveraging quadratic transformation (QT) and element-wise block coordinate descent (EBCD) techniques. Numerical results demonstrate the effectiveness of the proposed design.
