中文摘要：
近年来,QoS（Quality of Service）路由问题已成为Ad hoc网络的一个研究热点.本文提出一种按需的多径QoS路由协议—MTBP（Multipath Ticket Based Probing Routing Protocol）.该协议能够在源节点和目的节点间找到多条满足QoS要求的路由.与传统路由协议相比,本协议通过“票”限制洪泛,在链路断裂时采用备份路由及时恢复数据分组的传递,具有多路径传输、负载平衡、控制开销小等特点,能很好的适应无线移动自组织网中网络拓扑结构变化迅速,节点间移动速率快的特性.
英文摘要：
The study on QoS （Quality of Service） routing for Ad hoc networks is becoming a hotspot in recent years. In this paper, a novel on-demand QoS route protocol MTBP, called as Multipath Ticket Based Probing Routing Protocol, is presented. This protocol could search multi-paths according to QoS requirements of services. Comparing with the conventional route protocols,MTBP uses tickets to restrict flooding, and uses alternate route at intermedial node to deliver data packets when link failure occurs. MTBP is robust enough while it has good performance in load balancing and control overhead. It＇s well suitable for Ad hoc network whose topology always changes dramatically due to the high-speed movement of nodes.
