An Enhanced Time Space Priority Scheme to Manage QoS for Multimedia Flows transmitted to an end user in HSDPA Network

摘要: Abstract — When different type of packets with needs Quality Service (QoS) requirements share the same network resources, it became important to use queue management and scheduling schemes in order maintain perceived quality at end users an acceptable level. Many have been studied literature, these time priority (to QoS for Real Time (RT) packets) and/or space Non (NRT) packets). In this paper, we study show drawback a combined (TSP) scheme used manage RT NRT intended user High Speed Downlink Packet Access (HSDPA) cell, propose enhanced (Enhanced Basic-TSP scheme) improve relatively packets, exploit efficiently resources. A mathematical model EB-TSP is done, numerical results positive impact
