Misbehavior Detection Embedded with Agent Based Routing in Delay Tolerant Networks

K. Deepika ^[3] | Sujatha S G

Abstract: In a Delay Tolerant Networks depend Routing schemes depends on the intermediate nodes to carry messages till the destination. Intermediate node forwards the messages to other nodes till the destination. Malicious and selfish behaviors represent a serious threat against routing in Delay Tolerant Networks so it may decrease the performance of network. Thus, efficient and faster spreading of messages and the selfish node detection is essential to reduce the delay of sending a message from source to destination. In this paper, we aim to design a new agent aided routing scheme to avoid large message delivery delay and detection of selfish node to increase the performance in Delay Tolerant Networks. Here, the source of a message is permitted to create unlimited copies of a message and distribute these copies to agents. Agents acting as the representative of the sources receive messages from the sources based on their node visited list and delivery predictability. After that, the agents forward the copies to the other neighboring agents. Thus, the agents help in faster and efficient dissemination of a message in the network which helps in reducing message delivery delay. Misbehavior detection scheme, for secure DTN routing toward efficient trust establishment. For detection of selfish node the basic idea of iTrust is introducing a periodically available Trusted Authority (TA) to judge the node-s behavior based on the collected routing evidences and probabilistically checking. The extensive analysis and simulation results demonstrate the effectiveness and efficiency of the proposed scheme.
