E-DROP: An Effective Drop Buffer Management Policy for DTN Routing Protocols
In Delay Tolerant Networks (DTN) disruptions may happen frequently as end to end path is not available all the time. Thus, delays can also be extended due to its environment nature like deep space, underwater, ocean sensor networks. In manage to achieve message delivery probability in such demanding networking situations, researchers have proposed the design of store-carry-and-forward routing protocols, here a node might accumulate a message in its buffer and carry it next to for unlimited time, awaiting till a suitable forwarding opportunity acquire .Moreover, multiple message duplication into the network to increase delivery probability. This arrangement of long-standing storage and replication force a high storage overhead on network.
