Performance Analysis of a DTAG Recovery Method in DTN with Multiple Flows

In this paper, we introduce the impact of multiple flows on the performance of Dynamic Threshold-based Anti-packet Generation (DTAG) recovery method in Delay/Disruption/Disconnection Tolerant Networking (DTN), which considers grid road maps. Unlike typical recovery methods that use anti-packets, the DTAG approach reduces node storage usage by considering the number of new bundle messages around vehicles. The DTAG has the ability to generate anti-packets at intermediate nodes before the bundle messages reach their end-point. The simulation results have shown that a high delivery rate can be maintained while storage usage and overhead are reduced, even when network flow increases.
