PERFORMANCE ANALYSIS FOR RESOURCE MANAGEMENT IN INTEGRATED CELLULAR/WLAN NETWORKS
To utilize the total resources in cellular/WLAN integration for both cellular and WLAN network, their different channel allocation strategies should be considered and efficient resource management techniques are required. In this paper, we proposed a new call admission scheme to utilize the coupled resources effectively. Proposed scheme, by taking the different resource sharing strategies of both network, limits the new, horizontal and vertical handoff voice and data call arrivals together with call-level QoS requirements. In cellular network, all admission parameters are obtained by searching algorithm. In WLAN, due to preemptive priority of voice calls, the access of data calls into channel is restricted while voice calls are admitted as long as there is sufficient bandwidth. From the numerical analysis, it is shown that integrated network uses the resources effectively and provides the all upper bound QoS requirements to voice and data users.
