Survey on congestion control for DTN
DTN拥塞控制研究进展*

As an emerging network architecture,delay/disruption tolerant networks(DTN) have been widely investigated in challenge networks, such as IPN etc. Congestion control is a key problem in DTN.The standard TCP congestion control mechanism is not able to handle the special properties of long delay, frequent disruption, no end-to-end path simultaneously, and the network nodes have the capability of limited storage/processing. In particular the custody transfer pose significant challenges. Many approaches have been proposed to overcome these difficulties.This paper gave an overview over exiting proposals, explained their key ideas and showed their interrelations.Finally,also indentified open research issues, and intended to motivate new reaserach efforts.
