摘　　要：本文提出了一种基于虚拟网格划分的拥塞控制和能量平衡路由协议(congestion control and energy balance,CCEB),该协议利用多主节点、多路径地选取和更新方法,有效地均衡了网络能耗,延长了网络生命周期.在路径选择过程中,该协议综合考虑了下一跳节点的剩余能量、队列占有率以及前向度量指标,使靠近Sink节点的网格内拥有更多的转发主节点.在数据转发阶段,利用预测的方法对各节点进行拥塞检测和能量判断,避免使用发生拥塞或者剩余能量较少的节点转发数据.最后,通过NS2仿真平台实验,验证了CCEB协议在均衡能耗和缓解拥塞方面的有效性.In this paper,we propose a virtual grid-based congestion control and energy balance routing protocol(CCEB),which chooses multiple master nodes and updates multiple paths to fairly use the energy of the forward nodes to maximizethe network lifetime.In the process of path selection,the proposed protocol takes the residual energy,the queue occupancyand the forward metric of next hop into account to ensure the grid close to the Sink to have more master nodes.In theprocess of data forwarding,the proposed protocol uses predictive methods for congestion detection and energy detection toavoid using congestion node or low residual energy node to forward data.Finally,the experiments on the NS2simulationplatform verify the CCEB protocol’s effectiveness in balancing energy consumption and alleviating network congestion.
