摘要：
In this paper we propose a new media access control (MAC) protocol that can support various ATM traffics efficiently in wireless ATM network environment. Since wireless channel is error-prone and has scarce bandwidth, an important issue is to devise an appropriate MAC protocol to allocate the limiting resources to each user efficiently as well as to meet the desired QoS of each connection. In the proposed MAC protocol, we design an efficient scheduling algorithm that can support variable characteristics of VER traffic well and allocate data slots fair: The leaky bucket functionality in the base station (BSI is used to improve the performance and reduce the complexity of the scheduling algorithm. Consequently the proposed MAC protocol can reduce and bound the delay rime of real time traffics while meeting the QoS requirements of other traffics. The simulation results also show that our protocol outperforms than the other schemes no matter when the system load is low or high.
