Genetic Approach to QoS Optimization for WCDMA Mobile Networks
David Soldani, Kimmo Valkealahti · 2005
This paper presents a genetic approach to optimal QoS provisioning for WCDMA networks. Using a genetic algorithm, several parameters are changed simultaneously to maximize the percentage of satisfied users of the offered services upon different input traffic mixes. The gains provided by the optimal parameter settings compared to default network configurations are expressed in terms of spectral efficiency. Simulation results show clear values for the network administrator to implement different QoS provisioning for distinct input traffic mixes and the proposed genetic approach to be a feasible method for multi-parameter optimization.
