A neighbor-aware congestion control mechanism for delay-tolerant networks

Abstract

Delay-Tolerant Networks (DTNs) are special types of network environments that are subject to delays and disruptions. Traditional end-to-end congestion control mechanisms are hard to be implemented in the DTNs due to frequent intermittent connections. In this paper, we propose a new hop-by-hop congestion control mechanism. This mechanism can be integrated into any quota- replication DTN routing protocols with a few modifications. Experimental results show the superiority of this kind of congestion control over existing types presently in use. © Springer-Verlag Berlin Heidelberg 2013.
