Adaptive Channel Allocation for Cellular Networks using the Bandwidth Aware Call Admission Control for Sub-Channels (BACAC-SC)

The call admission control (CAC) is the method for the absorption of the handoff and new calls in the cellular cluster. The CAC methods are designed for the control of the channels in the given cellular cell in the popular singular or multiple pooling of the channels. The concept of the reserve channels is popular among the cellular techniques for handling of the handoff or the handover calls. The proposed model is based upon the sub-channel allocation over the reserve channel allocation policy. The sub-channel allocation method requires the computation of the available bandwidth shared among the multiple users and to control the bandwidth with the absorption of the new user. The sub-channel allocation method requires the number of computations altogether or in the hierarchical fashion for the realization of the minimized data drop rate based evaluation. The proposed model has been evaluated by using the probability of dropping the handoff calls and the probability of the blocking of the new calls. The proposed model has been clearly outperformed the existing model in most of the cases in the cellular cluster.
