Investigating Performance of Extended Epidemic Routing Protocol of DTN under Routing Attack

Nodes in the DTN work on the foundation of cooperation in the network. When working in a cooperative manner, these nodes consume some network resources like bandwidth, buffer space etc. Like any other networks, DTNs are also prone to the malicious nodes and different attacks. In this work, we have proposed an attack model comprising of falsification of extended routing protocol metadata information combined with drop all attack. We have proposed the attack model definition and analyzed the performance of extended Epidemic routing protocol of DTN under this attack model. From the simulation results, we analyzed that the delivery probability of extended Epidemic routing protocols is greatly affected by the proposed attack model whereas the DTN routing protocols are proved to be robust against the individual attacks when implemented independently of each other.
