Abstract

A server sharing model is presented to model the downlink scheduler in 3G wireless networks. This model is used to find the average achievable service rate per user for a given fairness criterion. The wireless channel is modeled by a Finite State Markov Channel (FSMC) to reflect the effect of Adaptive Modulation and Coding used in 3G wireless networks. This model can be used to implement differentiated services in 3G wireless networks. It facilitates QoS control on the last hop, i.e., the wireless link. The results obtained show that this methodology provides qualitative and quantitative evaluation of the wireless link sharing mechanism in 3G wireless networks.
