Development of a secure delay tolerant epidemic routing protocol
Abstract
Delay or Disruption tolerant networks (DTNs) are networks in which an end-to-end path among a
set of nodes is not always guaranteed. Examples of such networks are underwater networks, deep
space networks, and remote and rural area communication. In extreme situations of lack of end to
end connectivity, DTNs nodes store the messages and carry it, till it finds a suitable relay node to
forward the message to the destination. Most of the existing researchers focused on developing
smart routing protocols for DTNs. However, The security features of the messages being
transported, such as confidentiality and integrity, have been largely disregarded in the existing
literature and makes the messages prone to other threats along the path. So, in this project, we
have addressed the issue of secure routing in DTNs and proposed a method with the help of public
key cryptography using RSA and we have conducted various experiments and the results show
improvement in the routing performance metrics. Experimental results show that by incorporating
the security features, DTN performance metrics, such as delivery ratio, overhead ratio and delivery
delay have been improved compared to traditional epidemic routing protocol.
