Improving the Performance of a DTN with Transportation System in Tirana City
Trans Motauto World, Vol. 6 (2021), Issue 1, pg(s) 20-23
Delay Tolerant Networks (DTNs) enable communication in networks with low density, low connectivity and high mobility. DTNs are suitable in areas where an infrastructure does not exist. DTNs use store-carry-forward approach. The performance of such networks is strongly connected with nodes mobility. Vehicles can be part of DTNs. In this paper we will investigate the role of buffer size and vehicles of transportation system as message forwarders in a DTN in Tirana city. The performance metrics for evaluation are delivery probability, average latency and overhead ratio. The simulation results show that transportation system can be used as a backbone for DTNs in urban areas.
