A New Dynamic Pricing Scheme with Call Admission Control to Reduce Network Congestion

Due to the importance of congestion in networks, we look for a method that can reduce the network congestion, in recent years considerable efforts have focus on the call admission control that provide the desired QoS but cannot reduce the network congestion, so in this paper we introduce a new scheme that add an additional dimension (dynamic pricing) to CAC in order to reduce congestion. Dynamic pricing encourages users to use resources efficiency. In this scheme price depends on the network load so it can reduce congestion. We compare the performance of our scheme in term of congestion prevention with conventional systems where no pricing block is implemented. These results show improvement that can be achieved by the integration of pricing in the call admission control process in networks.
