摘　　要：由于无线传感器网络的资源受限,相比传统网络其传输过程更容易导致丢包和拥塞。为了避免和控制拥塞,本文提出了一种利用功率分配重新选择路径的拥塞控制算法,首先参考路径传输的多种Qo S相关参数度量网络的路径代价和节点可用资源,基于测量得到的网络拥塞水平通过传输功率递增和递减选择不同的路径控制网络拥塞。仿真结果表明所提出的协议减少了网络时延,提高了系统吞吐量和网络生命周期。Due to the limited resources,wireless sensor networks is more likely to lead to packet loss and congestion in the transmission processing comparing to the traditional network. In order to avoid and control congestion,we present control algorithm based on power allocation. Firstly,the information of paths’ cost and network nodes’ resources are measured by referring to a variety of related Qo S parameters. For network congestion control,the transmission power will increase or decrease to select different route node. Simulation results show that the proposed protocol can reduce the network delay,improve the system throughput and increase the network lifetime.
