Security in vehicular ad hoc networks

IEEE Communications Magazine, 2008
Vehicular communication networking is a promising approach to facilitating road safety, traffic management, and infotainment dissemination for drivers and passengers. One of the ultimate goals in the design of such networking is to resist various malicious abuses and security attacks. In this article we first review the current standardization process,

Synchronous Relaying in Vehicular Ad-Hoc Networks

International Journal of Wireless Networks and Broadband Technologies, 2011
In this paper, the authors propose a simple concept for emergency information dissemination in vehicular ad-hoc networks. Instead of competing for the shared wireless medium when transmitting the emergency information, the authors’ proposed method requires nodes to cooperate by synchronizing their transmissions.

In-Network Aggregation for Vehicular Ad Hoc Networks.

IEEE Commun. Surv. Tutorials, 2014
In-network aggregation mechanisms for vehicular ad hoc networks aim at improving communication efficiency by summarizing information that is exchanged between vehicles. Summaries are calculated while data items are generated in and forwarded through the network.

Localization in Vehicular Ad Hoc Networks

2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05), 2005
Communications between vehicles constitute a Vehicular Ad hoc Network (VANET). Contrary to MANET in VANET nodes which are vehicles can move with high speed and generally must communicate quickly and reliably. When an accident occurs in a road or highway, alarm messages must be disseminated, instead of ad-hoc routed, to inform all other vehicles.

Vehicular Backbone Network Approach to Vehicular Military Ad Hoc Networks

MILCOM 2013 - 2013 IEEE Military Communications Conference, 2013
We consider a tactical command center that issues broadcast data message flows for dissemination to all vehicles traveling as team members of a convoy, or along a multilane linear road segment. We propose a networking protocol which uses location aware data to identify and elect certain vehicles that reside at preferred locations to act as relay nodes,

Privacy protection on Vehicular Ad hoc NETworks

International Journal of Ad Hoc and Ubiquitous Computing, 2011
Vehicular Ad hoc NETwork (VANET) provides traffic safety and efficient traffic management by taking advantage of messages that are quickly interchanged among vehicles and some infrastructures. The integrity and non-repudiation of messages and vehicle privacy in VANET are quite critical. Pseudonym technology is a practical strategy to ensure these three

Vehicular Ad Hoc Networks

2009
A vehicular ad hoc network consists of smart vehicles on the road and provides communication services among nearby vehicles or with roadside infrastructure. It is envisioned to provide numerous interesting services in the near future. This chapter first introduces the basic application scenarios of vehicular ad hoc network and its unique ...

Enhancing unlinkability in Vehicular Ad Hoc Networks

Proceedings of 2011 IEEE International Conference on Intelligence and Security Informatics, 2011
Communication messages in Vehicular Ad-hoc Networks (VANETs) can be used to track movement of vehicles. In this paper, we address the problem of movement tracking and enhance location privacy without affecting security and safety of vehicles. By considering unique characteristics of VANETs, we firstly propose a synchronized pseudonym changing protocol ...

Fuzzy cognitive Vehicular Ad hoc Networks

2011 IEEE 7th International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2011
The Wireless Access in Vehicular Environments (WAVE) protocol stack is one of the most important protocols proposed to standardize and allocate spectrum for vehicle-to-vehicle and vehicle-to-infrastructure communication. In a previous work, we proved that WAVE faces a spectrum scarcity problem which hinders reliable exchange of safety information.

Reliable broadcast in vehicular ad-hoc networks

2013 9th International Wireless Communications and Mobile Computing Conference (IWCMC), 2013
For most safety-related applications that are envisaged in VANETs, the provisioning of a real-time medium access control is of great importance. However, the ability to access the wireless medium in a collision-free and time-bounded manner is particularly challenging in networks with unreliable wireless channel and dynamic topologies.
