Joint Power and Rate Control Algorithm Based on Genetic Algorithm

从最小化系统的中断概率和功率消耗的角度出发,给出了一种新的联合功率和速率控制算法。称之为基于遗传算法的联合功率和速率控制算法-GAJPR算法。算法要求所有移动用户根据他们的位置、QoS和密度协调他们的发射功率和传输速率。模拟结果表明:GAJPR算法相对于对功率和速率完全没有控制的情况的性能提高是巨大的。

A joint power and rate control algorithm based on genetic algorithm was proposed. The goal of the algorithm is to minimize the power consumption and outage probability of the systems. It requests that the mobile users＇ transmission power and rate should be coordinated and assigned according to the users＇ locations, QoS and density. The simulation results show that this algorithm may tremendously save system power and cut down the users＇ power consumption, and, at the same time, can make the systems maintain their capacity and information throughput on a higher level.
