Paper Abstract

One key issue of providing multimedia services over a mobile wireless network is the quality of service (QoS) support in the presence of changing network connectivity. The trend of using pico-cells in wireless networks to gain more spatial efficiency increases the rate of call handoffs when mobile users move from one cell to another. Frequent handoffs make it very difficult to support QoS for multimedia applications. In this research, we investigate a potential solution to meet the challenge of seamless resource transition during frequent handoffs by combining the differentiated QoS service model and the priority handoff mechanism. We perform simulations with OPNET. Results show a tradeoff between system utilization and handoff blocking rates for different QoS classes.
