Information centric network for secure data transmission in DTN

Abstract

Delay Tolerant Network (DTN) is characterized by mobile nodes and dynamic network topology. There are some selfish / malicious nodes (termed as misbehaving) present in the network resulting in the packet loss. Currently these are identified only after data transmission. The core idea of this paper is to ensure secure data transmission in DTN in the presence of misbehaving nodes. This is achieved by means of ICN (Information Centric Network) which supports node mobility and interactivity. Here ICN is used along with DTN. ICN intimates about misbehaving nodes in the path so that alternative path is chosen. The packets reaches the destination safely. This paper will be implemented in two parts. In the first part the misbehaving nodes are identified. In the second part alternative path is chosen for the packets so that further transmission by misbehaving nodes is prevented. Thus the proposed system ensures secure data transmission in the network.
