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 route can discover a bypass on-demand to bypass the congestion node.When data flow gets to the node with a bypass,they are distributed in primary path and bypass proportionally.As a result,it can realize the congestion adaptive function.The simulation results show that the CA-AODV protocol can obtain less delay from the average end to end,higher data delivery ratio,less normalized overhead as compared to AODV.
