Defending Disruption Tolerant Network From Misbehaving and Malicious Nodes
Disruption Tolerant Network (DTN) is the key area in the fields of wireless network and is prone to high delay and disruption. DTN are designed to provide communications in the most unstable and stressed environments, where the network would normally be subject to frequent and long lasting disruptions and high bit error rates that could severely degrade normal communications. DTN network's endpoints aren't always continuously connected. In order to facilitate data transfer, DTN uses a store-and-forward approach across routers that are more disruption-tolerant. A node misbehaves by dropping data that it carries around. It drops packet even if has sufficient buffers. This results in wastage of system resources.
