Bio-inspired uplink power control for energy-efficient mobile stations in wireless cellular networks

Abstract

In this paper, we propose a distributed uplink power-control algorithm inspired by the flocking behavior in birds as a means of improving the energy efficiency of mobile stations (MSs) in a wireless cellular network. Just as each bird in a flock attempts to match its velocity with the average velocity of the adjacent birds, in the proposed algorithm, each MS in a cell matches its uplink rate with the average uplink rate of the co-channel MSs in adjacent cells by controlling its transmission power. Simulation results show that the proposed power-control algorithm effectively reduces the power consumption in the MS, while maintaining a low outage probability, which eventually improves the energy efficiency of the MS.
