Abstract

In this paper, an optimal power control scheme is proposed for applying in-band full-duplex (FD) communication in multi hop wireless networks subject to full interference, such as home wireless mesh networks. Considering both the selfinterference due to FD operation and the inter node interference from all nodes, an optimization problem is formulated for maximizing the end-to-end throughput, and a linear programming based solution is developed for obtaining the optimal power allocations. Via detailed numerical experiments, it is shown that our solution outperforms a prominent FD multi hop scheme in the literature, where power control is based on single hop interference only. Furthermore, it is shown that FD multi hop with proposed optimal power control can triple the end-to-end throughput of a traditional HD multi hop network for low power, short range systems, and 80% improvement can be achieved for higher power. A hybrid FD-HD multi hop scheme is also proposed for cases when FD cannot be enabled on all nodes, and it is shown that the throughput of HD can be doubled with the hybrid scheme for moderate size networks.
