Abstract
This paper presents a dynamic bandwidth allocation scheme for new and handoff voice calls in cellular networks. The main idea of the new scheme is based on monitoring the elapsed real time of handoff calls and according to both a time threshold (t e ) and a dynamically changing bandwidth threshold (B t ) parameters, a handoff call is either prioritized or treated as a new call. Also in this paper, we introduce a crucial general performance metric Z that can be used to measure the performance of different bandwidth allocation schemes and compare them. Z, which is a performance/cost ratio, is a function of the new call blocking probability, handoff call dropping probability and system utilization all together. The results indicate that our scheme outperforms other traditional schemes in terms of performance/cost ratio, and maintains its superiority under different network circumstances.
