Multihop Communication In Delay Tolerant Network

Abstract

Most routing protocols in DTN uses redundant transmission to reduce data transmission delay.
Delay/Disruption Tolerant Network is designed for intermittently connected network where network partitions are
frequent and very high delays are associated with some links. Due to lack of consistent connectivity, DTN routing usually
follows store-carry-and-forward; i.e., after receiving some packets, a node carries them around until it contacts another
node and then forwards the packets. Routing is one of the major issues affecting the overall performance of DTN
networks in terms of resource consumption and data delivery. This paper contains survey on multihop communication in
DTN.
