Vehicular Ad Hoc Networks (VANET) are useful in implementing a smart transportation system by enabling ad hoc vehicle to vehicle communication. Sybil attack is considered to be one of the most dangerous threats to VANET. Sybil aggressor can produce different phony personalities with false messages to extremely hinder the ordinary elements of wellbeing related applications. In this paper, we are presenting an implementation of a method to detect Sybil attack using received signal strength indicator.

This chapter introduces node localization techniques in ad-hoc networks including received signal strength (RSS), time-of-arrival (TOA) and direction-of-arrival (DOA). Wireless channels in ad-hoc networks can be categorized as LOS and NLOS. In LOS channels, the majority of localization techniques perform properly. However, in NLOS channels, the performance of these techniques reduces. Therefore, non-line-of-sight (NLOS) identification and mitigation techniques, and localization techniques for NLOS scenarios are briefly reviewed.
