Abstract:

This paper proposes an optimal dynamic transmission power allocation mechanism for multiple users to maximize mobile ad hoc networks (MANETs) energy efficiency. With the widespread adoption of the internet of things (IoT), energy efficiency is a crucial metric in MANETs constrained by the battery capacity of portable devices. Specifically, a practical scheme needs to be explored that ensures the quality of service (QoS) while minimizing battery costs. Previous studies mainly focus on designing power-manageable components and achieving predictive mechanisms at the circuit or system layer. In contrast to the traditional approaches, we jointly consider power management and multiuser cooperative mobility for energy efficiency maximization. On the one hand, we formulate the dynamic power allocation schemes with multiuser cooperative mobility strategies into the infinite-horizon time average problems. On the other hand, an algorithm based on Lyapunov optimization is developed to obtain the optimum, i.e., dynamic power allocation based on the multiuser cooperative mobility (DPA-MCM) algorithm. Numerical simulations show that the proposed algorithm improves the energy efficiency by up to 27.84 % compared to the previous method, demonstrating the effectiveness.
