An efficient distributed joint power and admission control algorithm

We consider the joint power and admission control problem for a wireless network consisting of multiple interfering links. The goal is to support a maximum number of links at their specified signal to interference plus noise ratio (SINR) targets while using a minimum total transmission power. We presented a centralized new linear programming deflation (NLPD) algorithm for the joint power and admission control problem, which was shown to outperform the state-of-the-arts. In this work, we develop a distributed implementation of the NLPD algorithm. We propose to use the projected alternate Barzilai-Borwein (PABB) algorithm with the continuation technique to carry out power control. This power control strategy enables each transmitter to update its power efficiently and locally with limited information exchange. Numerical simulations are reported, illustrating the effectiveness of the developed approach.
