MASCARAPRADOS调度算法性能仿真
MASCARAPRADOS調度算法性能倣真
MASCARAPRADOS조도산법성능방진
WAND (Wireless ATM Network Demonstrate)是欧洲ACTS (Advanced Communication Technologies and Services)支持的项目之一。在WAND中采用一种基于集线器式、自适应TDMA方式的MAC协议——MASCARA，它通过预约与竞争相结合的方法，为无线ATM(WATM)终端提供具有QoS保证的宽带无线接入。文章着重分析了MASCARA中基于时延的优先权调节调度(PRAD0S)算法，并给出了几种不同情况下的算法性能仿真结果。

The Magic WAND (Wireless ATM Network Demonstrator)is one of the largest projects within the European Union ACTS (Advanced Communications Technologies and Services). The MAC protocol of the Magic WAND ,known as MASCARA,is a hub-based,adaptive TDMA scheme which combines reservation- and contention- based access methods to provide multiple access efficiency and quality-of-service guarantees to wireless ATM terminal connections. In this paper,a Prioritized Regulated Allocation Delay-Oriented Scheduling (PRADOS)in MASCARA is presented. And the results of the simulation of a number of scenarios are presented to assess the performance of the proposed algorithm.
