    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 utilisation in the IP-based RAN, Resource Management in Diffserv (RMD) is proposed [1]. RMD is a simple and scalable bandwidth resource management scheme that extends Differentiated Services for on-demand resource reservation and admission control. We evaluate Measurement-Based Admission Control (MBAC) algorithms for RMD. An MBAC algorithm proposed in literature was selected, namely the Time Scale Decomposition (TSD). The main reason for choosing the TSD algorithm is that this algorithm is less dependent on traffic assumptions. In the TSD algorithm, two variants are speci- fied. The first variant is based on per flow measurement statistics (TSD-FE criterion), which is not scalable. The second one uses aggregate measurement statistics (TSD-AE criterion). The main disadvantage of TSD-AE is that it provides poor utilisation performance due to inaccurate estimation of traf- fic statistics. Therefore, we enhance TSD-AE to improve its utilisation performance. A performance evaluation of different variants of TSD is conducted, the results show that our proposal, the TSD-EAE outperforms TSD-AE.
