Delay Tolerant Network (DTN) is a wireless network that experience frequent and long duration partitions during transmission of data. The fully connected path from source to destination is unlikely to exist. And due to the existence of contemporaneous connectivity between nodes, network topology may change dynamically and randomly. This leads to a problem of how to route a packet from one node to another in DTN. Most of the nodes in DTN are mobile, so that the connectivity is established when they come into the transmission range of each other. The design of a routing protocol for this type of network is an important issue. This work, surveys various routing strategies in Delay Tolerant Networks.
