Distributed power control in full duplex wireless networks

In this paper, we consider the problem of distributed power control in a full duplex (FD) wireless network consisting of multiple pairs of nodes, within which each node needs to communicate with its corresponding node. We aim to find the optimal transmit powers for the FD transmitters such that the network-wide capacity is maximized. Based on the high signal-to-interference-plus-noise ratio (SINR) approximation and a more general approximation method for logarithm functions, we develop effective distributed power control algorithms with the dual decomposition approach. The proposed algorithms are validated with simulation studies.
