BANDWIDTH RESERVATION POLICY PERFORMANCE ANALYSIS IN A WIRELESS CELLULAR NETWORK UNDER NON-EXPONENTIAL DISTRIBUTIONS
R. Nandhini · 2015
Past studies in bandwidth reservation strategies in wireless multimedia cellular networks use the exponential distribution for service time and inter-arrival time distributions. But in real world (example like GSM/GPRS), inter-arrival, service time and cell residence time in cellular systems have been shown to be non-exponential. As a result, network performance could be worse than that reported in the literature. The main objective of this paper is to investigate the impact of the network performance under various non-exponential distributions on a specific bandwidth reservation policy. The threshold-based bandwidth reservation policy has been taken into consideration and its performance is observed under different inter-arrival time distributions, and channel holding time distributions. The network performance is measured in terms of new call blocking probability and handoff call dropping probability.
