Disruption-Tolerant Networks (DTNs) can be used as a communication means in the emergency context when communication infrastructure is unavailable. In DTNs, mobile user devices such as smartphones act as “data mules”: they store, carry and forward messages. Unfortunately, the “storing” part is especially vulnerable to denial-of-service (DoS) attacks since an attacker can flood the network with bogus information and, thus, replace or purge valid messages from a node’s buffer.

In this thesis, you will implement and evaluate a novel, DoS-resistant buffer management scheme in IBR-DTN [1], DTN implementation written in C++, which also runs on standard Android smartphones.
