用遗传算法优化WCDMA网络QoS
Optimization of Quality of Service for WCDMA Networks Using Genetic Algorithm
摘要
Abstract
3G cellular systems are targeted at supporting various applications such as voice, data, and multimedia over packet switched networks. Providing QoS ( Quality of Service) to guarantee for these applications is an important objective in the design of the WCDMA (Wideband Code-Division Multiple Access) wireless networks.This paper presents a genetic approach to optimize the QoS for the WCDMA networks. Using a GA ( Genetic Algorithm ), we investigate how WCDMA network parameters can be changed simultaneously to maximize the percentage of satisfied users of the offered services with respect to different input traffic mix. Simulation results shows that GA is an efficient method that can be used to automate network parameter settings according to input traffic mix, in order to maximize the services'performances. It was observed that, using GA, the network could achieve up to 18% spectral efficiency gain and the GA convergence speed was reasonably good, for example, optimal parameter configuration was obtained after 20 to 30 iterations in all analyzed traffic mix scenarios.关键词
