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. In addition, different applications will have different requirements on handoff support for different quality of service (QoS). Therefore, an efficient handoff support which can satisfy various QoS requirements and give high resource utilization is one of the critical issues for mobile multimedia networks. This paper introduces a resource allocation scheme for handoff, called measurement-based dynamic bandwidth reservation (MBDBR). This scheme dynamically reserves bandwidth for handoffs according to the strength of the signal received by the mobile user. The simulation results show that MBDBR possesses good performance in terms of call blocking probability, call dropping probability and bandwidth utilization
