Performance Evaluation Of Position-Based Channel Reservation For Handoff Of Cellular Calls

In this paper, we evaluate the performance implications of incorporating guard channels and reservation queuing into a position-based predictive channel reservation scheme. The paper also investigates the impact of the value of the distance threshold, a parameter used to control the timing of sending channel reservations and examines the benefits of reservation pooling, a mechanism introduced to reduce the negative impact of cell congestion on the QoS of ongoing calls. The simulation results give good insight into several design approaches that significantly improve the predictive scheme
