Abstract:Â The Delay-Tolerant Networks (DTNs) are the type of emerging networks characterized by very long delay paths and frequent network partitions. For the distinct characteristics of DTNs, routing becoming one of the most challenging open source problems. Recently years numerous approach has been presented for addressing routing issues in DTNs. This paper mainly surveys DTN routing strategies and gives a comparison of them with respect to different performance metrics. In this especially, we summarize the cardinal mobility models and DTN simulators which are significantly important to evaluate the performance of the DTN routing protocols.
