| 摘 要： | 针对WSN多路径路由的拥塞问题，根据快速转发数据和节能的原则，提出了基于多路径路由的拥塞控制算法（CCAMR），CCAMR包含新路径建立、RBR与RER值获取及新路径撤销算法，通过建立新路径将拥塞区域的流量转移到负载较轻的区域，有利于避免和缓解重度拥塞．仿真结果表明，与CODA相比，CCAMR的丢包率和能耗更低，能够保证多路径路由下带宽分配的公平性，具有更高的拥塞解除效率．

| Abstract: | Aiming at the congestion problem to principles of fast data forward and energy of the multi-path routing in WSNs, according saving, a Congestion Control Algorithm Based on Multi-path Routing（CCAMR） was put forward, which including the establishing of new path, the getting of RBR and RER and the removing of new path. By establishing a new path, CCAMR transfered the traffic of congestion area to the area with lighter load, this a- void heavier load. Simulation results shows, compared with CODA, the packet loss rate and energy consumption of CCAMR is lower, the efficiency of congestion remove is higher, which can ensure the fairness of bandwidth allocation under the circumstance of the multi- path routing. |
