ADAPTIVE BANDWIDTH MANAGEMENT FOR UMTS NETWORKS

Abstract

Universal Mobile Telecommunications system (UMTS) provides the technical foundation to integrate all kind of services like speech, data, audio, video, e-mail, web browsing etc. through the mobile hand set. The objective here is to improve bandwidth utilization and quality of service of Universal Mobile Telecommunications System. To improve bandwidth utilization of Universal Mobile Telecommunications System performance management information base (P-MIB) has been implemented which dynamically adjusting the packet scheduler and admission controller. The P-MIB also controls the system parameters to improve overall quality of service. The key contribution of this dissertation is to compare the performance of two packet scheduler i.e., weighted round robin scheduler and weighted fair queuing schedulers. The two packet schedulers are implemented so that maximum number of packets are transmitted in less time unit, which in turn maximizes the bandwidth utilization. The implementation is die in c++ language on Pentium IV system under windows-98 environment.
