A call admission protocol for cellular networks that supports differentiated fairness

Call admission protocols play a central role in determining the performance of any network. The call admission protocol must decide either to accept a call or reject it; at the same time, it must deal with different classes of calls that have different bandwidth and quality of service (QoS) requirements, and different priorities. It must also maintain some form of fairness (depending on QoS) and maintain a reasonable utilization of the channel. We assume a cellular system and we present a new call admission protocol. Our protocol is simple to implement, and it can support differentiated fairness in call acceptance. We also present a Markov chain representation of a system using our proposed protocol. Finally, we present simulation results in order to compare our protocol to previous protocols and show that our protocol can achieve the required differentiated fairness without sacrificing channel utilization.
