Trust Management in Vehicular Ad-hoc Networks: Extensive Survey

Over the past few decades, Intelligent Transportation System (ITS) has become a vital and extensive element of daily human life activity. Vehicular Ad hoc Networks (VANETs) have most promising components ITS, which promises to enhance transport efficiency, passenger safety, comfort by exchanging traffic infotainment information intelligent vehicles. Moreover, VANETs emerged with new paradigms (e.g., Cloud, SDN (Software-Defined Networking), Fog computing, Blockchain, AI (Artificial Intelligence) techniques) provide strategic secure communications increase their reliability. Therefore, efficient robust mechanisms, such as trust management, are essential requirements in VANETs. This survey provides an overview VANET management’s main concepts. After that, we briefly review existing surveys, followed significant challenges security Then, identify, review, classify, summarize, compare related approaches. Finally, give some future research directions.
