Abstract: Delay Tolerant Network (DTN) are promising techniques to
enable data transmission in challenging scenarios where sophisticated
infrastructure is not available and the end-to-end path does not exist at
the moment of data transmission. These networks are characterized by
a long delay, intermittent connectivity and high error rates.
Furthermore, the dynamic topology of the network may change
randomly. Therefore, routing is one of the most crucial issues that
affect the performance of DTN in terms of data delivery, latency and
using resources if node mobility is considered. The routing design in
DTN raises many challenges to the networks. Therefore, the problem
of how to route a packet from one node to another in DTN is of the
essence. This paper puts forward a rigorous survey of various routing
protocols as well as performs a comparison of diverse routing
strategies regarding significant issues in DTN.
