DeVANET: Decentralized Software-Defined VANET Architecture

摘要

Vehicular adhoc networks come out to be a promising solution for ensuring traffic and road safety on highways. However this area induces communication challenges such as topology dynamics, and connectivity losses. Today's Vanet demand a sound planning to make architectural level decisions. Integrating Vanet with emerging Software defined Networking brings ground-breaking networking innovation. Recent researches in SDN based Vanet are useful but their performance goals drops in large scale VANETs. In this research we are going to exploit SDN planes by partitioning Vanet to work in distributed manner. The proposed architecture is tested on VEINS testbed which provides interactive environment to perform road traffic simulations. Simulation results show an increase in performance gains as compared to traditional Vanet architectures.
