Paper Abstract

Quality of Service (QoS) is an important issue in the next generation wireless networks providing multimedia services. In this paper, we address the connection-level QoS provisioning in wireless multimedia networks, measured by the connection blocking and dropping probabilities. The connection-level QoS for multimedia services are guaranteed by achieving the minimum connection blocking probability subject to the constraint on the handoff dropping probability. A dynamic call admission control scheme is proposed to provide connection-level QoS in wireless multimedia networks. This scheme adopts a novel strategy called prompt-decreasing/timer-increasing (PDTI) to dynamically adjust the threshold for handoff channel reservation. It can maintain the handoff dropping probability at a target rate predefined in the system specification, while maximizing resource utilization and minimizing the new call blocking rate. The proposed solution is a measurement-based method that is practical for real-world deployment. Simulations are carried out to prove the efficiency of the proposed PDTI scheme.
