Extended Abstract: File Transfer in Vehicular Ad-Hoc Networks

Abstract

A large amount of file transfer systems in use today are designed to operate in wired networks. In the context of vehicular ad-hoc networks, these systems may behave improperly, due to the inherent characteristics of wireless networks and mobility of vehicles. This work proposes and implements a model for transferring files using basic clientserver architecture, with focus on its operation in vehicular networks. We performed two different sets of experiments. The first experiment was performed to evaluate the performance of the system with different number of clients and servers while the purpose of second experiment was to validate the application behavior in an outdoor environment. The results show that the system is able to perform file transfers. It is concluded that the number of clients has a great impact on performance of the system.

A beaconing-based roadside services discovery protocol for vehicular ad hocnetworks

“…In the last few years, vehicular ad hoc networks (VANETs) received much attention from different standardization organizations, research communities, educational institutions, transportation departments, and automobile industries on a global scale. VANETs are a special class of mobile ad hoc network (MANET) [1]. These networks are distinguished by the high speed of vehicles, small intercontact times between hosts, different operational environments, variable densities of vehicles, short-range communications, intermittent connections, and real-time data exchange requirements.…”

A privacy-preserving reputation scheme for trust management on VANETs applications

“…Mobile Ad Hoc NETwork (MANET) is an autonomous system made up of mobile stations interconnected by wireless connections without the management of a centralised infrastructure. VANET is a subclass of MANET in which the vehicles act as moving nodes forming a dynamic network topology and can play the role of a router to relay data (ULLAH et al, 2013). The nodes travel at much higher speeds compared to the traditional MANET and can take predictable routes randomly.…”

On the use of opportunistic vehicular communication for roadside services advertisement and discovery

“…Its main objectives are to improve the quality of life by solving transportation problems (ASIA, 2015). Vehicular Ad hoc Network (VANET) is a promising technology for ITS and is playing an important role to meet the objectives of ITS, i.e., saving people lives and properties by minimizing road accidents, reducing traffic congestion and jams, and providing comfort and convenience to the travelers by allowing access to different infotainment services.VANETs are special class of Mobile Ad hoc Networks (MANETs) (ULLAH et al, 2013), in which vehicles act like moving nodes. These networks are distinguished by the high speed of vehicles, small inter-contact times between hosts, different operational environments, variable densities of vehicles, short-range communications, intermittent connections and real-time data exchange requirements.…”
