Abstract

Delay-Tolerant Networks (DTNs) are a type of emerging networks characterized by very long delay paths and frequent network partitions. For the distinct characteristics of DTNs, routing becomes one of the most challenging open problems. Recent years numerous approaches have been presented for addressing routing issues in DTNs. This paper surveys main DTN routing strategies and gives a comparison of them with respect to the performance metrics. Specially, we summarize the cardinal mobility models and DTN simulators which are significantly important to evaluate the performance of DTN routing protocols.
