AI Technical Summary
Existing power and resource optimization techniques for TS-SWIPT multi-hop networks suffer from high computational complexity, difficulty in real-time deployment, neglect of actual hardware constraints leading to the inability to directly implement the optimal solution in real-world systems, lack of efficient discrete optimization methods, and poor versatility and stability.
A discrete binary search power allocation method for TS-SWIPT multi-hop relay networks is proposed. Under the premise of satisfying the end-to-end communication rate, the discrete transmit power of the source node and the continuous time switching ratio of each relay are jointly optimized. An efficient feasibility determination sub-step and a binary search method are designed to directly find the minimum feasible power on the discrete power set.
It enables real-time, online power and resource allocation on resource-constrained IoT nodes, obtains the globally optimal solution, reduces network energy consumption, extends network lifetime, is suitable for edge devices with limited computing power, and has low computational complexity and high scalability.
