Disruption/Delay-Tolerant Networks (DTNs) have been proposed as a means to provide communication to the population when infrastructure-based networks (e.g., cellular network) has been destroyed by a natural disaster or brought down by a cyber attack. In DTNs, end user devices (smart phones) relay messages for each other using direct wireless communication such as Wi-Fi or Bluetooth.

Many works have attempted to improve these networks by proposing novel routing protocol strategies and buffer management schemes. However, evaluation of such networks has so far only been carried out via simulation and a rather low number of nodes (< 1000), e.g., [1].

The goal of this thesis is to investigate the feasibility of DTNs in a metropolitan scale. For this, you will have to drastically increase the scalability of an existing network simulator (e.g., the ONE [2]) to enable simulation of realistic scenarios. In the next step, you will identify problems of current routing and buffer management approaches and come up with strategies to improve their scalability.
