Channel congestion control in mobile cellular networks: A survey

This article produces a review of call admission control and resources allocation schemes for cellular networks users and the findings in this area. Our goal is to provide survey of reviewed researches of a broad classification and detailed discussion of the existing call admission control schemes and allocation of bandwidths allocations that reduce the congestion issues in the network environment. The discussion of several admission control schemes and their comparison in terms of performance metrics: complexity, flexibility, stability, adaptively, overhead were all looked at holistically and analysed as a motivating factor for this work, and the future trends in Teletraffic engineering. It is therefore discovered that some schemes are better than the others in curtailing the resource utilization crises in cellular network.
