A TRUST BASED SCHEME TO DETECT SELFISH NODES USING DELAY TOLERANT NETWORK

Chandrima Chakrabarti

Abstract :

Physical and communication infrastructure will be totally damaged after a major disaster. Delay Tolerant Network (DTN) can be implemented with smart phone carried by volunteers to handle the devastating situation under control. In this situation, some malicious nodes may drop or corrupt data to make the situation difficult to handle. DTN is a network where the communication infrastructure and network connectivity are not guaranteed. Messages are transmitted from source to destination through multi-hop approaches. Checker detects selfish nodes and if they do not get any mismatch in transmission of node’s messages within maximum time limit then the node is good in performance else not. In our scheme, forwarder nodes are chosen based on good reputation of nodes and nodes with bad reputation are repelled from the network. Hence we propose a reputation based scheme for improving the performance of the network and simulations are done using ONE simulator.
