A new CAC protocol for optimizing revenue and ensuring QoS

Call admission control (CAC) protocol will try to be fair, fast, reducing inconveniences, and maintaining quality of service (QoS) at the time of deciding whether a call request will be accepted or rejected into a network or communication system. A good CAC should have the ability to select the calls among the requested calls in such a way so that maximum fairness is justified by its performances at the sometime it should achieve some targets such as maximizing the revenue considering the constraints of the network system such as limited bandwidth. In the todaypsilas communication world the demand of bandwidth increases sharply due to the different users different types of service requirements such as audio, video, voice etc. from the same communication system. Besides need to deal with different tariff. So considering all these issues a CAC needs to decide which call requests should be admitted or not, which is obviously a critical and difficult task. In this paper a new CAC protocol is proposed that can select the best calls for the communication system, it can optimize the generated revenue from the network system, it can handle the different call admission situations in a fairness way, it can consider the different priorities based on class, can maximize the revenue of the communication system and also maintains the overall QoS for any network or communication system. Empirical results have shown its excellent performances for any network and communication platform.
