Performance and Energy Consumption Analysis of a Delay-Tolerant Network for Censorship-Resistant Communication
Delay Tolerant Networks (DTNs) composed of commodity mobile devices have the potential to support communication applications resistant to blocking and censorship, as well as certain types of surveillance. We analyze the performance and energy consumption of such a network, and consider the impact of random and targeted denial-of-service and censorship attacks. To gather wireless connectivity traces for a DTN composed of human-carried commodity smartphones, we implemented and deployed a prototype DTN-based microblogging application, called 1am, in a college town. We analyzed the system during a time period with 111 users. Although the study provided detailed enough connectivity traces to enable analysis, message posting was too infrequent to draw strong conclusions based on user-initiated messages, alone. We therefore simulated more frequent message initiations and used measured connectivity traces to analyze message propagation. Using a flooding protocol, we found that with an adopti...
