Abstract
We propose and analyze the performance of the MAC layer protocol to support efficiently various ATM traffic, such as CBR, VBR, ABR and UBR, in wireless ATM network environments. The proposed MAC protocol could extend efficiently the service discipline of ATM traffic from the wired network to wireless ATM network environments. Thus, the available bandwidth, which remained except the bandwidth for CBR and VBR traffic, could be effectively allocated to ABR and UBR traffic. Especially, a 2-level scheduling algorithm supports successfully the variable characteristics of VBR traffic. In this paper, an MMDP(3)/D(3)/1/K(3) system model is used for performance analysis, and the analysis results show that the proposed method provides effective performance in wireless ATM environments.
