Abstract

IP-based radio access networks (ranss) are envisaged to be the next generation access networks in UMTS. In order to provide a satisfactory level of quality of service (QoS) for real-time applications, and efficient network resource utilisation in the IP-based RAN, resource management in diffserv (RMD) is proposed. RMD is a simple and scalable bandwidth resource mangement scheme that extends differentiated services for ondemand resource reservation and admission control. This paper investigates measurement based admission control (MBAC) algorithms for RMD. In 2 we proposed the time scale decomposition enhanced aggregate estimation (TSD-EAE) algorithm as MBAC for RMD. Our next step is to investigate the impact of traffic burstiness on the performance of TSD-EAE and compare it against other MBAC algorithms in the literature. The study is conducted by using an RMD network simulator and a MPEG-4 traffic simulation model. The simulation results show TSD-EAE compares favourable against other MBAC algorithms. Because TSD-EAE is robust in keeping the packet loss and delay low while achieving high level utilisation.
