a mar-based qos routing in long-distance wireless networks
Long-distance wireless networks are expected to provide multimedia traffic service in addition to basic Internet access, as more and more such networks have been emerged in real life. However, few work has been done on QoS provisioning in this area. 2P MAC has been successfully deployed in many long-distance networks for its efficiency. In this paper, we propose a QoS routing - Maximum Allocation with Reservation-based (MAR) QoS Dynamic Source Routing (MQDSR) on 2P MAC. MQDSR integrates bandwidth reservation and admission control in route discovery mechanism, according to MAR bandwidth constraints model. Simulation results in NS2 show that MQDSR can provide QoS support in terms of end-to-end delay and throughput for traffic with high and normal priority, while avoiding the starvation of the best effort traffic.
