Performance Evaluation of Non-prioritized and Prioritized Call Admission Control Schemes in Wireless Cellular Networks

Prioritized New Call Threshold Policy for Wireless Cellular Networks

“…In this policy, it has to be ensured that the system guarantees potentially different QoS requirements and also provides the essential service differentiation from diverse applications. Another necessity is the complete utilization of the scarce wireless bandwidth of the wireless cellular networks [1,2].…”

“…In order to achieve this continuity during the movement of the users between the cells, the Handoff (or handover) process is utilized. In Handoff process, the change of the channel (the frequency, the time slot, the spreading code, or a combination of them) associates with the actual connection while a call is in progress [1,2].…”

“…Moreover, the CAC scheme is also expected to decrease the blocking possibility of the new calls, besides expectation about the maximization of channel use. But it is not easy to meet all these conflicting requirements, and there are tradeoff relationships between the parameters [1,2].…”

“…A lot of research has been carried out on the domain of CAC for wireless cellular networks [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. If there is a need for a comprehensive review of the work done on CAC, please, refer to [1], in which a discussion on general concepts of cellular wireless networks, review of the work done in mobility modeling domain, and an overview of CAC schemes were provided.…”
