Abstract
This paper presents an advanced bandwidth reservation technique to improve Quality of Service (QoS) by reducing the forced call termination during handoff. One solution to ensure continuity of on-going calls and reduce the forced call termination during handoff is to predict Mobile Station (MS) trajectory and do resource reservation in advance. So, we propose a new scheme that uses an accurate mobility prediction algorithm to predict MS next location and uses this data in bandwidth reservation scheme to improve QoS. The performance of the algorithm is evaluated via simulations. The simulation results show that our algorithm reduces handoff call drop rate without over reserving the resources hence it improves bandwidth utilization and reduces new call blocking rate.
