MIMO Techniques for Jamming Threat Suppression in Vehicular Networks

Abstract

properly cited.Vehicular ad hoc networks have emerged as a promising field of research and development, since they will be able to accommodate a variety of applications, ranging from infotainment to traffic management and road safety. A specific security-related concern that vehicular ad hoc networks face is how to keep communication alive in the presence of radio frequency jamming, especially during emergency situations. Multiple Input Multiple Output techniques are proven to be able to improve some crucial parameters of vehicular communications such as communication range and throughput. In this article, we investigate how Multiple Input Multiple Output techniques can be used in vehicular ad hoc networks as active defense mechanisms in order to avoid jamming threats. For this reason, a variation of spatial multiplexing is proposed, namely, vSP4, which achieves not only high throughput but also a stable diversity gain upon the interference of a malicious jammer.

Cyber Ranges and TestBeds for Education, Training, and Research

“…CR research teams should be focusing on improving various aspects of their testbeds. In addition, modern CRs should be enriched with novel features, such as various telecom-munication capabilities, emulated Banking systems, hospitals [81], simulated smart grids, automated vehicles [82], Virtual Cyber Centres of Operation, wireless sensor networks, real time Intrusion Detection Systems [83], honeypots [84], novel authentication mechanisms [85], mobile security scenarios, and several privacy mechanisms. By adding these features, new attack scenarios can be easily deployed on a testbed, revealing vulnerabilities of the various systems and thus giving the researchers the opportunity of developing innovative defence mechanisms.…”

Smart Cars and Over-the-Air Updates

“…Finally other novel methods can be used as defence mechanisms for smart cars. Recently the authors in [16] proved that multiple input multiple output techniques can be used in vehicular ad hoc networks as active defense mechanisms in order to avoid jamming threats. Combined with novel techniques that can estimate the speed of a jammer [15]and thus calculate the area where the communication is blocked and take appropriate routing decisions can further improve OTA performance.…”

Intrusion Detection System for Platooning Connected Autonomous Vehicles

“…For the evaluation of the jamming attack scenario, a reactive radio frequency jammer has been implemented [18]. The RF jamming targets the IEEE 802.11p Orthogonal Frequency Division Multiplexing (OFDM) based PHY layer operating in the 5.85-5.925 GHz unlicensed national information infrastructure band, with 10 MHz bandwidth.…”
