Abstract :
This paper considers optimizing the utilization of radio resources in a heterogeneous networks consisting of a WLAN and a CDMA network. We propose a joint admission control scheme for multimedia traffic that exploits vertical handoffs as an effective tool to enhance radio resource management while guaranteeing handoff users´ QoS requirements. The network resources utilized by the vertical handoff user are captured by a link utility function. A signaling cost is used to model the signaling and processing load incurred on the network when vertical handoff is performed. The performance of the joint admission control scheme is analyzed based on the formulation of the admission control actions. Voice and data applications are considered in the performance evaluation, and the simulation results show that the proposed scheme can efficiently relieve the congestion, balance the load and improve the overall network reward.
