| 摘 要： | 介绍了自组网内的延迟限制 ＱｏＳ（Ｑｕａｌｉｔｙ－ｏｆ－Ｓｅｒｖｉｃｅ）路由算法，并对它进行了仿真。该算法可在网络状态信息不精确的情况下，同时并行寻找多条路径，以优化路径选择。当节点移动、离开、加入时，引入容错机制，以便于路径保持。通过仿真可以看出，该算法在适度的寻路代价下，可以得到较高的呼叫接收率。

| Abstract: | This paper describes the delay - constrained QoS routing protocol for ad hoc network. Multiple paths are searched in parallel to find the most qualified one with imprecise state information. Fault -tolerance techniques are brought in for the maintenance of the routing paths when the nodes move, join, or leave the network. Our simulation shows that high call - admission ratio and low - cost paths are achieved with modest routing overhead. |
