Power Control Algorithm for Providing Packet Error Rate Guarantees in Ad-Hoc Networks

We investigate the issue of power control in mobile ad-hoc networks under distributed resource allocations, where the interference at the receivers is not known in advance. Based on a model that captures the physical layer and power control issues more accurately, we develop a new power control algorithm that can provide a physical/link layer quality-of-service in the form of packet error rate. We then formulate the problem of minimizing the average aggregate transmission power as an optimization problem, and show that our proposed power control algorithm converges to a solution of the optimization problem.
