—Recently, indoor positioning systems (IPSs) have been designed to provide location information of persons and devices. The position information enables location-based protocols for user applications. Personal networks (PNs) are designed to meet the users' needs and interconnect users' devices equipped with different communications technologies in various(More)
Universal Mobile Telecommunications System (UMTS) is a third-generation mobile communication system that supports wireless wideband multimedia communications. This paper investigates the performance of streaming MPEG-4 video over UMTS dedicated channels with varying channel conditions. In order to evaluate the performance, simulation models for UMTS and(More)
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 util-isation in the IP-based RAN, Resource Management in Diff-serv (RMD) is proposed [1]. RMD is a simple and scalable bandwidth(More)
