Analysis of Combined Adaptive Bandwidth Allocation and Admission Control in Wireless Networks

Abstract— An analytical model is developed for cellular networks with a combined adaptive bandwidth allocation and trafficrestriction mechanism. Instead of focusing only on the bandwidth utilization and forced-termination probability, we derive two important Quality-of-Service (QoS) metrics, degradation ratio and upgrade/degrade frequency. We show numerically that these two metrics must be taken into account in order to support the QoS specified by each client. The effects of system loads and clients’ mobility on system performance are also investigated. Even under the various distributions of mobility, the simulation results are shown to match our analytical results, implying the applicability of our analytical model to more general cases.
