Empirical capacity modeling and evaluation of delay tolerant network routing protocols

Delay tolerant networks under wireless intermittent settings have gathered growing research interests in recent years. There remains, however, a lacking of performance modelling results for DTN protocols. In this paper, we propose to model the system-level performance of DTN protocols using the Erlang B queueing model, and profile the performance metrics such as message delivery ratios under different traffic conditions using the system capacity measurements. A number of common DTN protocols are evaluated using a scenario based on map-based mobility under different settings.
