延迟容忍网络中自适应拥塞控制机制研究
Adaptive congestion control mechanism for delay tolerant networks
摘要
Abstract
Delay Tolerant Network(DTN)is a kind of restricted network.Due to the unstable delivery paths and high delivery latency in DTN,the congestion control methods applied in traditional networks are not suitable here.This paper proposes an Adaptive Congestion Control mechanism based on Node State(ACC-NS).To satisfy different kinds of quality requirements,messages are classified into special messages and general messages.The special messages ask for higher delivery ratio.Nodes are classified into three levels according to their congestion state.Each node decides reception action based on its congestion state and current buffer usage ratio.To delete the redundant message copies,VACCINE and message encounter based countering method are combined.Compared with the other two existing routing protocols,simu-lation results show that ACC-NS achieves better performance.关键词
