Abstract
IP-based radio access networks (RANs) 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 utilization in the IP-based RAN, resource management in diffserv (RMD) is proposed. RMD is a simple and scalable bandwidth resource management scheme that extends differentiated services for on-demand resource reservation and admission control. This paper investigates measurement based admission control (MBAC) algorithms for RMD. In H.el Allali et al., (2006), 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 favourably against other MBAC algorithms. Because TSD-EAE is robust in keeping the packet loss and delay low while achieving high level of utilization
