Joint Power Control and Time Division to Improve Spectral Efficiency in Dense Wi-Fi Networks

P. 1-5.

Ubiquitous densification of wireless networks has brought up the issue of inter- and intra-cell  interference. Interference significantly degrades network throughput and leads to unfair channel resource usage, especially in Wi-Fi networks, where even a low interfering signal from a hidden station may cause collisions or block channel access as it is based on carrier sensing. In the paper, we propose a joint power control and channel time scheduling algorithm for such networks, which significantly increases overall network throughput while maintaining fairness. The algorithm is based on branch-and-bound global optimization technique and guarantees that the solution is optimal with user-defined accuracy.
