Vanet applications vulnerability and attacks detectionand avoidance

الملخص EN

Vehicular ad-hoc network (VANET)are designed to aid in avoiding many of the traffic problems, such as accidents, traffic jams, traffic status broadcast, etc.

This article proposes two possible configurations as VANET applications to aid in solving two traffic issues namely, parking, and after-accident management.

These two models of VANET are designed with the objective of improving traffic fluidity.

However, VANETs are special types ofMobile Ad Hoc Networks (MANETs) with moving nodes (Vehicles) and stand still nodes Roadside Units (RSUs).

Likewise, all MANETs.

The network nodes can move freely within the network coverage yet stay connected.

Therefore, VANETS are subject to vulnerable attacks.

Sybil attacks are the most threatening VANET attacks that may lead to death. 
Therefore, this article proposes a three-stage technique for detection, prevention, and avoidance of Sybil attacks.

It also presents a methodology for analyzing the algorithms of VANET applications to identify predictive security holes and hence suggests a method for closing these threatening gaps, which are exemplified on the two sample applications for explanation.
