摘　　要：拥塞控制是无线传感器网络能耗优化中的一项重要技术,文中算法针对分簇式路由算法中存在的拥塞问题提出基于拥塞控制的无线传感器网络能耗优化路由算法(CCERA).算法通过跨层设计方法,在路由算法中引入MAC层的缓冲区队列信息检测网络中的拥塞情况并进行解除.仿真结果表明,该算法相比于LEACH、UCRA、FPCRA算法,数据包发送量至少提高了33%,网络生命周期至少提高了16%,第一个死亡节点出现时间至少延迟了20%.The congestion control is an important method to save energy for wireless sensor networks(WSN).In order to solve the congestion problem,a Congestion Control and Energy Optimization Routing Algorithm for Wireless Sensor Networks(CCERA)is proposed.A congestion control mechanism based on cross-layer design is proposed,which can detect the congestion by introducing the buffer queue length of Medium Access Control(MAC)layer and further judge the trend of buffer queue length by congestion factor.All these methods contribute to reduce the network congestion.Compared with Low-Energy Adaptive Clustering Hierarchy(LEACH)algorithm,Uneven Clustering Routing Algorithm(UCRA)algorithm,and Fuzzy Power-optimized Clustering Routing Algorithm(FPCRA)algorithm,the proposed algorithm increases the transmission amount of data packets by at least 33%and the time when the first node dies is delayed by at least 20%,the network lifetime is prolonged by at least 16%.
