DTN routing: Secure message transmission in border defence system

Delay tolerant networks have already evolved as a pragmatic solution to various requirements such as delayed routing in wireless networks. They can also be used in place of traditional wireless networks in the border areas or highly sensitive areas, thus contributing to the data security in such places. In this paper, a border security architecture has been proposed where DTN is used for transferring messages within the army units of a particular region that are deployed in harsh terrains, thereby ensuring integrity and security of the message. In the proposed approach, a special property of the nodes is used which makes them self disposable in nature after either their mentioned TTL gets over or whenever data tampering takes place in the node. So, the message as well as the node will be definitely safe from getting accessed in an unauthorized manner.
