Future wireless networks promise multimedia communication and computing services for both fixed and mobile users. One of the most important challenges of wireless multimedia service for mobile users is maintaining a guaranteed quality of service over end-to-end connections. The use of micro/pico-cellular architectures is one of the promising ways to improve the capacity of mobile multimedia networks with reuse of the scarce radio spectrum. However, the handoff rate is increased with decrease of the cell size. An efficient handoff supporting which can satisfy various QoS requirements and give high resource utilization is one of the critical issues for mobile multimedia networks. In this paper, a handoff scheme that called dynamic channel reservation based adaptive quality of service handoff algorithm is introduced. Performance comparisons are made to the performance of other handoff schemes.
