To reduce the call blocking probability (CBP) and call dropping probability (CDP) of real-time and non-real-time traffic in wireless multimedia networks, it is frequent to employ resource reservation to achieve the above-mentioned goal as well as to avoid long latency of path rebuilding. However, pure resource reservation may lead to inefficient resource utilization and increase of CBP and CDP due to frequent handoff in wireless networks. To reduce unnecessary resource reservation, the prediction of moving direction can be incorporated to enhance the pure resource reservation. Therefore, a dynamic resource reservation scheme with mobility prediction is proposed in this paper. In this scheme, a resource request with available range rather than a fixed resource request is specified by each traffic to make the reservation scheme flexible. Using simulation results, we show that mobility prediction can dynamically adjust resource reservation and effectively enhance system resource utilization. Moreover, the available interval of resource request gives flexibility to resource reservation which also improves the system performance.
