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 (A. Bader et al., 2005). RMD is a simple and scalable bandwidth resource management scheme...
Universal Mobile Telecommunications System (UMTS) is a third-generation cellular network that enables high-speed mobile Internet access. This paper evaluates the performance of the transmission control protocol (TCP) Vegas and compares its performance with TCP Reno in a UMTS environment. Bulk data transfer was considered in the simulation with varying radio channel conditions. Data losses were assumed...
