Call admission protocols play a central role in determining both the performance of any network and the revenue (number of customers using the network and their degree of satisfaction) of the network. Call Admission Control (CAC) is such a provisioning strategy to limit the number of call connections admitted into the networks in order to reduce network congestion and call blocking incurred by higher priority call streams. The call admission protocol must decide either to accept or reject the call when both new and handoff call arrive. In this paper, the preference is given to the handoff call when compared to the new call in order to satisfy the QOS of the particular call.
