Considered as a primordial component of Cooperative Intelligent Transportation Systems (C-ITS), Vehicular Ad Hoc Network (VANET) plays a weighty role to facilitate different on-road applications, most of which primary rely on multi hop communications. To ensure reliability and security of such communication, it is very pertinent to guarantee that the most proper and trustworthy vehicles are selected...
Detecting malicious and selfish nodes is an important task in Vehicular Adhoc NETworks (VANETs). Various proposals adopted trust management as an alternative solution for it is less costly in terms of computation delay and mobility adaptation, compared to the cryptography-based solutions. However, the existing solutions assume that in general the attackers have always a dishonest behavior that persists...
Vehicular Ad-hoc Networks (VANETs) are a promising approach to increase road safety, turning VANETs into critical infrastructures in the near future. Recently, it was shown that Radio Frequency (RF) jamming has a disruptive effect in VANET communications in ranges of several hundred meters in open space areas and up to 50 m around intersections in constructed areas. Hence, it is critical to study...
Vehicular Ad-hoc Network (VANET) is a sub class of mobile ad-hoc networks. VANET provides wireless communication among vehicles and vehicle to road side equipments. The communication between vehicles is used for safety, comfort and for entertainment as well. The performance of communication depends on how better the routing takes place in the network. The life saving factor is also the key issue in...
This paper proposes guidelines for the design of dissemination protocols for data sensed in vehicular environments in view of a number of potential applications. We organize the data dissemination process in three main tasks: discovery, assessment, and seizing of data exchange opportunities. One major problem is the limitation in bandwidth due to large amounts of data and short communication time...
Localization and exchanged position information plays a big role in Vehicular Ad-Hoc Networks (VANET). Several network services and applications, such as safety messages, require location information. The data are exchanged between vehicles within their radio communication range. In real life implementation, direct communication can be interfered and blocked by obstacles on the road preventing two...
Vehicular Ad-Hoc Networks (VANETs) have the potential to optimize traffic in modern urban areas, reduce congestions and pollution, and increase passenger safety and comfort. Applications designed for such networks pose new security constraints. The mobile devices have limited resources to spare, and the network connectivity is reduced because of the mobility of cars. We present a security protocol...
