Delay Tolerant Networks
(DTN) are characterized by intermittent connectivity between nodes causing parts of an end-to-end path to be formed at different times, though a complete end-to-end path may not exist at any time. In such networks, messages are buffered at nodes, and forwarded as and when a contact with the next hop is made. Typically, broadcasting in DTNs uses some variation of flooding. Such schemes generate a large number of extra messages that may need to be buffered and may not work well in resource-constrained scenarios such as low buffer size at nodes or nodes with energy constraints.
