Wireless ATM MAC layer protocol using WDWEDF and two-phase scheduling algorithm

In this paper, we propose and evaluate the performance of Wireless ATM MAC laver protocol to support efficiently various ATM traffics, such as CBR, VER, ABR and UBR, in wireless ATM network environments for reverse and forward link. The proposed MAC protocol could extend efficiently the service discipline of ATM traffics from wired network to wireless ATM network environments. Thus, available bandwidth. which is remained except the bandwidth for CBR and VER traffics, could be effectively allocated to ABR and UBR traffics. Especially. in view of reverse link, two-phase scheduling algorithm supports successfully variable characteristics of VER traffic. And, in view of forward link. Wireless Dynamic Weighted Earliest Deadline First' scheduling algorithm minimizes the mean cell delay and required buffer size. Simulation results show that proposed method provides effective performance in wireless ATM environments.
