| 摘 要： | 针对现有多跳无线自组网路由协议以被动方式对拥塞进行处理，有可能导致更多的分组丢失、更长的时延和更大的网络开销问题，提出了一种基于辅助路由的拥塞自适应协议（congestion adaptive protocol based on aided-routing, CAPAR）。该协议以主动方式对拥塞进行处理，采取建立辅助路由的方法对发送给拥塞节点的业务流量进行分流，主动避免拥塞的发生，克服了以被动方式对拥塞进行处理所带来的不利影响。给出了CAPAR协议的建立过程，证明了CAPAR协议的正确性，并对其路由存储代价和路由更新代价进行了分析。结果表明，与其他按需路由协议相比，CAPAR减少了重新建立路由所带来的开销和时延，其路由更新代价明显降低。

| Abstract: | In existing routing protocols for multi-hop wireless Ad hoc networks,congestion is taken into consideration only after congestion has happened,and this passive manner may result in more packets loss,longer delay and more overhead.This paper proposes a congestion adaptive protocol based on aided-routing(CAPAR) for multi-hop wireless Ad hoc networks.CAPAR deals with congestion in an active manner by establishing aided-routing and shunts the traffic which is sent to the potential congestion node.Therefore,CAPA... |
