摘要随着多媒体及实时应用的普及,在移动自组网中为业务流提供服务质量保证现已成为研究热点。提出一种在大规模移动自组网中提供服务质量保证的分段式路由协议。该协议采用直线逼近的方法,逐段建立满足带宽要求且延迟小的路径,并选择到源节点和目的节点连线距离最近的节点作为转发节点。通过分段、独立地维护路由,减小了路由维护的代价,提高了可扩展性。模拟结果表明该路由协议具有路由成功率高、路径短和延迟小等特点。 With the increasing popularity of multimedia and real-time applications, QoS routing has become a hot research topic in Mobile Ad-hoc NETworks（MANETs）. This paper proposes a QoS-aware segment-by-segment routing protocol in large-scale MANETs. In the proposed protocol, each routing path is built segment by segment with linear approximation. At the routing discovery phase, the node on the line from source node to destination node has highest priority to be chosen as the next forwarding node. At the route maintenance phase, the proposed protocol independently maintains the routing path seg- ment by segment. So it can reduce the cost of route maintenance and scale well in large-scale MANETs. Simulation studies show that the proposed protocol can get high routing success ratio, short routing path and low routing delay.
