Model Predictive Joint Transmit Power Control for Improving System Availability in Energy-Harvesting Wireless Mesh Networks

摘要

This letter explores energy-efficient transmit power control in wireless mesh networks (WMNs) with energy harvesting sources, where both users and WMN links are considered to decide an optimal energy utilization scheme. Specifically, a model predictive control algorithm is proposed based on user distribution and harvested energy predictions. Extensive simulation results show that the proposed algorithm outperforms the static and current information-based transmit power control schemes in high user density environments.
