摘　　要：针对无线传感器网络(WSN)中易产生的网络拥塞问题,提出了一种新型跨层自适应WSN拥塞控制路由协议(CLCC),通过路由层获取数据链路层的缓冲队列信息来进行拥塞检测,而拥塞控制方法是根据邻居节点信息表建立新的传输路径,并调节上游节点的数据发送速率。仿真结果表明,CLCC协议能有效降低网络拥塞引起的数据丢包率、端对端传输延迟和网络能耗。In view of the congestion problem in thewireless sensor network （WSN）, anew adaptive WSN routing cross layer congestion control protocol（CLCC） is given in this thesis. The key of cross layer design is to use the routing layer to get the buffer queue information of MAC layer to detect congestion. It can control the congestion through the establishment of new transmission path and the adjusting node data sending rate. The simulation results show that the CLCC protocol can effectively reduce data packet loss rate, end-to-end transmission delay and network energy consumption caused by the network congestion.
