| 摘 要： | 提出局部拥塞表概念,利用旁路、局部拥塞表和hello消息机制,对动态源路由(Dynamic source routingprotocol,DSR)协议进行改进,提出了拥塞适应动态源路由(Congestion adaptive dynamic source routing,CA-DSR)协议。在CA-DSR协议中,主节点利用局部拥塞表,能在第一时间感知到网络拥塞,当拥塞发生时,拥塞节点的上一节点能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,实现了路由拥塞适应功能。协议利用hello消息对局部拥塞表进行有效维护。与DSR相比,CA-DSR协议中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。仿真结果已证明了CA-DSR协议的优点。 |

| Abstract: | A concept of local congestion table is presented and a dynamic source routing(DSR) protocol is improved based on bypass,local congestion table and hello message systems.A routing protocol of congestion adaptive dynamic source routing(CA-DSR) is proposed.In the CA-DSR protocol agreement,a primary node can be aware of the network congestion by using local congestion table.When a congestion happens,the previous node of the congestion node on the primary route try can find a bypass path to go around the congest... |
