Abstract—This paper proposes a Self-Adaptive Interactive Navigation Tool (SAINT), tailored for cloud-based vehicular traffic optimization in road networks. The legacy navigation systems make vehicles(More)
—In order to support efficient data services on vehicular networks, we propose a Data-oriented Cluster-based Media Access Control Protocol (DCMAC). For Intelligent Transportation Systems (ITS), the demand for data services is increasing. Furthermore, most of vehicles will be equipped with Dedicated Short-Range Communications (DSRC) devices in the near(More)
—Inspired by the advancement of vehicular networks and increasing concerns on driving safety, this paper proposes a framework of Context-Awareness Safety Driving (CASD). In vehicular networks, vehicles communicate with each other and share a variety of information. By utilizing those capability, CASD provides vehicles with a class-based safety action plan(More)
VANET, the Vehicular Ad-Hoc Network, treats cars as nodes in a mobile network. Not surprisingly, VANET must be very secured since one of the network characteristics allows the network to be open to public. The digital signature used in VANET is the standard, ECDSA, or Elliptic Curve Digital Signature Algorithms. ECDSA provides network security by employing(More)
