• Designed the most efficient(till date) algorithm to counter-attack the misbehavior(maybe unintentional) of the relay nodes during message routing in DTN(Delay Tolerant Network).
• Also, contributed to the strategy which makes use of trusted nodes, with special capabilities; of interacting with regular nodes to collect information about the network. Apart from this, we introduced two new strategies based on the previous ones to make trusted nodes connected using either satellite links or partial 3G links matching with the real-life networks, like post-disaster management or a military network.
• We concluded that a connected trusted checker with a full information share strategy produces almost
• cent percent of malicious nodes detection within 40% to 70% lesser time and lowest overhead compared to others.
• Implemented the algorithm in The ONE( Opportunistic Network Environment simulator ) which is written in Java. Analyzed terabytes of data for the results using Python and Bash scripts and generated thousands of result graphs using GNU-PLOT.
