  • A Dynamical Reserved Bandwidth Allocation scheme (DRBA) for handoff in multimedia mobile networks is presented to reduce the call dropping probability and improve the bandwidth utilization. The proposed scheme reserves bandwidth for real-time handoff calls and allows non-real-time handoff calls to borrow the over-booked bandwidth from real-time handoff calls when the free bandwidth is deficient. Simulation results show that reduction in dropping probability and increase in bandwidth utilization are obtained in our proposed DRBA scheme. It also provides fair QoS for different types of services.
