On Full Duplex Scheduling for Energy Efficiency Maximization in Multi-Hop Wireless Networks

With the rapid innovations in the design of transceiver for full duplex (FD) communications, the benefits of FD for single-hop wireless communications have been widely shown. But in a multi-hop wireless network, the benefits of FD with power control still need to disclose. The goal of this paper is to investigate the energy efficiency (EE) performance of FD scheduling in a multi-hop wireless network. In this paper, we explore FD on EE in multi-hop networks under optimal scheduling through strict mathematical model, formulation and proof. First, an EE model under FD scheduling with power control in multi-hop wireless networks is constructed. Then, through exploiting the reformulation linearization technique to reformulate and piece-wise linearization method to approximate, the nonlinear optimization problem for EE under FD is transformed into a linear one and solved with performance guarantee. Finally, simulation results validate the proposed optimization method to achieve the optimal EE under FD with power control compared to half duplex with power control and FD without power control.
