Performance analysis of a hybrid flooding-probabilistic DTN protocol using logged contact data
Constantino Rocha Antunes, Ricardo Morla · 2009
Abstract1 — In this paper we analyze packet delivery, buffer space, and transmission performance of a hybrid flooding-probabilistic DTN protocol using the DTN2 framework and one month of third-party logged contact data. This new protocol switches from probabilistic to flooding when the number of node contacts is below a threshold. Results show only 0.52 % fewer messages delivered compared to flooding and only 0.34 % and 0.16 % higher buffer occupancy and bandwidth usage costs compared to probabilistic and suggest that flooding could be used to improve probabilistic DTN performance at times when nodes are more isolated and contacts scarce.
