Performance Evaluation of a Real Vehicular Delay-Tolerant Network Testbed

Abstract

properly cited.Vehicular Delay-Tolerant Networks (VDTNs) are a breakthrough based DTN solution used to provide vehicular communications under challenging scenarios, characterized by long delays and sporadic connections. Using the store-carry-and-forward paradigm, this technology allows in-transit bundles to asynchronously reach the destination hop by hop over traveling vehicles equipped with short-range wireless devices. The VDTN architecture assumes out-of-band signaling with control and data planes separation and follows an IP over VDTN approach. This paper presents a real-world VDTN prototype evaluated through a safety application and a Traffic Jam Information Service. It also demonstrates the real deployment of this new vehicular communication approach. The real testbed is an important contribution since some complex issues presented in vehicular communication systems can be studied more accurately in real-world environments than in a laboratory approach. The results confirm that real deployment of VDTNs is doable and can be seen as a very promising technology for vehicular communications, although it requires appropriated technologies for outline interferences and quality of service support.

A comprehensive survey on simulators, emulators, and testbeds for VANETs

“…The real world testbed Vehicular Delay Tolerant Network (VDTN ) 87 testbed consists of a dedicated embedded hardware and software system. The embedded hardware includes a vehicle attached with a computing device, GPS, and IEEE 802.11b/g/n that operates at 2.4 GHz frequency spectrum.…”

A study of users' acceptance and satisfaction of emergency call service

“…Therefore, these safety systems are not reliable everywhere and every time. A simple way to solve this problem is to use, for example, the vehicular delay‐tolerant networks, which rely on node cooperation to accomplish such goal . For example, the authors in proposed an approach to improve the vehicular delay‐tolerant networks' efficiency.…”
