摘　　要：分布式并行服务器具有高的整体性能,用它作为网络服务器的Ad hoc网络,会体现出更好的服务性能。然而,无线系统的带宽有限,因此信道资源分配算法直接影响着分布式并行Ad hoc网络的性能。本文提出了一种适用于分布式并行Ad hoc网络的MAC协议DPACP,它根据通信节点的状态进行有选择的区分服务,采用混合服务规则满足不同优先级分组、不同通信节点的QoS需求。仿真表明,该协议对不同优先级分组均有良好的适应性,满足不同优先级的性能需求,对多业务的综合服务系统具有很强的适应性,从而使系统的稳定性大大增强,适用于分布式并行Ad hoc服务网络和用户网络。The distributed parallel（DP）server has high integrated performance. The Ad hoc networks which configure the DP servers will show the better service performance. However, the wireless system is a bands limited system, so, the channels allocation algorithm will straight affect the performance of the distributed parallel Ad hoc network. An adaptive MAC protocol for the distributed parallel Ad hoc network is presented in this paper, that is Distributed Parallel Access Control Protocol（DPACP）based on the nodes status. DPACP serves differently for varied nodes or packets with mixed rules. The simulation results indicate that DPACP can meet the demand of the performance asked by the varied PRI data packets,and also shows that it can fit for the varied integrated services system,and the stability is enhanced. So,DPACP is an adaptive protocol for the distributed parallel Ad hoc service and subscriber networks.
