Abstract

A bandwidth management scheme is proposed that can support the seamless QoS in face of handoff in mobile networks. The proposed scheme is based on the time-selective bandwidth reservation with the reduced signaling and computational overhead. The reservation parameters are adjusted dynamically to cope with user mobility. Throughout the computer simulations, the performance of the proposed scheme is evaluated. The simulation results show that the handoff call blocking probability can be remarkably improved with a slight degradation of other parameters such as new call blocking probability and bandwidth utilization efficiency.
