Using public buses as mobile gateways in vehicular clouds

Abstract

Recently Vehicular Ad Hoc NETwork (VANET) evolved to a rather more application and services-rich infrastructure referred to as VANET-based clouds. However the initial deployment stage of VANET is going to be crucial due to lack of proper infrastructure. In this paper, based on the predictability of time and space of the public buses in urban scenario, we use these buses as mobile gateways among vehicles on the road, VANET authorities, and cloud infrastructure. We consider data aggregation as a use-case for our proposed scheme where buses collect beacons and service requests from vehicles and send it to cloud, whereas cloud provides services to vehicles through buses. Additionally a real-time road network is considered in Seoul, South Korea where the public buses provide perfect connectivity among other vehicles. © 2014 IEEE.
