摘　　要：本文为移动自组网提出了一个基于动态蜂窝的QoS路由协议 ,它利用移动跟踪技术实现了一个分布式动态蜂窝生成协议 ;采用一个多QoS路由探测算法选择一条能够最大满足QoS要求的路由 ,并在这条路由上建立端 端主动资源预留 ;使用移动预测和被动资源预留技术预测源结点和目的结点可能进入的蜂窝集合 ,并在这些蜂窝集合与目的结点和源结点之间提前进行端 端被动资源预留 ;融合蜂窝动态检测技术与QoS路由修补技术自动发现和修补断裂的QoS路由 .由于该路由协议模仿了固定蜂窝网络中的操作 ,所以 ,大大改善了QoS路由的性能 .仿真结果表明 :在满足QoS条件下 ,它明显提高了包传输率 。Ad hoc Networks are wireless multihop networks that need a routing protocol to facilitate communication within the network.This article proposes a dynamic cellular based QoS routing (DC QoS routing) protocol for Mobile Ad hoc Networks (MANets).The protocol tracks the mobile nodes to setup a dynamic cellular system.Multiple QoS satisfied paths are probed in parallel to find the most qualified one and end to end resources are actively reserved along the selected path.The algorithms predict the mobility of the mobile nodes to create cellular sets that source/destination and intermediate nodes may enter.The end to end resources are passively reserved in advance along these predicted cellular sets.The cellular system is dynamically maintained and the broken path is auto detected and repaired.The proposed routing protocol simulates the operations of fixed cellular networks and improves the performance of QoS routing protocol in MANets.Simulation results show that high packet delivery rate is achieved with reduced routing load.
