| 摘 要： | 该文提出邻居拥塞表概念,利用旁路、邻居拥塞表、hello消息和下一绿色节点请求技术,对自组网按需距离矢量(AODV)协议进行改进,提出自组网拥塞适应按需距离矢量(CA-AODV)路由协议.在CA-AODV协议中,主节点利用邻居拥塞表,能在第一时间感知网络拥塞.当拥塞发生时,拥塞节点的上一节点能按需建立绕过拥塞节点的旁路,当数据流到达已建立旁路的节点时,被按比例分流在主路由和旁路上,实现了拥塞适应功能.仿真结果显示,与AODV相比,CA-AODV协议的平均端到端延迟更短、数据包递交率更高、规格化路由开销更少.

| Abstract: | This paper proposes a concept of neighbour congestion table,improves Ad Hoc on Demand Distance Vector(AODV) Protocol on the base of bypass,neighbour congestion table,hello message and Next Green-hop Requset(NGRQ) systems.A routing protocol of congestion adaptive Ad Hoc on demand distance vector(CA-AODV) is proposed.In CA-AODV protocol,a primary node can be aware of network congestion immediately by using neighbour congestion table.When congestion happens,the previous node of congested node on the primary ro... |
