A Vehicular Ad Hoc network is a subclass of Mobile Ad hoc Networks, to provide communication among vehicles and nearby road side units (RSUs). The main goal of VANET is providing safety and comfort for passengers. In this paper, two metrics to measure the connectivity and power requirement of RSUs in VANET have been proposed for power utilization of RSUs in VANET. Based on the metrics two metho...

We investigate the problem of scheduling of file distribution from Road-Side Units (RSUs) to vehicles in an urban environment. We suppose one RSU exist in each cross-road and all RSUs are connected to each other through a high speed backbone. Since the number of vehicles as well as the number and size of files are potentially large, scalable scheduling is a challenge. We first chop each file in...

We introduce a new scheme for safety message authentication in VANETs. For a practical implementation of VANET, we anticipate that road side units (RSUs) are not physically protected and are prone to several different attacks including node compromise attacks. Thus, an RSU should not be automatically trusted by on road vehicles. In our proposed scheme, a road side controller (RSC) is responsibl...

Vehicular ad hoc networks (VANETs) are the flaming topic of research. VANET comprises of moving vehicles communicating with each other. VANETs involve three types of communication: vehicle to vehicle (V2V), vehicle to roadside (V2R) or vehicle to infrastructure (V2I) communication. VANETs consist of some vital components: RSU, OBU and Trusted Authority. Among them Roadside units (RSUs) are one ...

This paper investigates the energy efficiency of Road Side Units (RSUs) by proposing a novel flow and energy management model in Software-Defined Networking (SDN)-based vehicular networks. In the considered scenario, high vehicular mobility and limited coverage area of RSUs cause a degradation in Quality of Experience (QoE) of vehicles and this significantly affects the quality of communication...

VANETs, as a subset of the MANETs, have progressed remarkably in recent years. These networks have an important role in improving traffic, road safety and driver service. In vehicle Networks, vehicle can Communication by vehicle-to-vehicle communication. Since there are fewer vehicles in the environment, there is no vehicle-to-vehicle connection in some areas. Therefore, they use Road Side Unit...

Vehicular Ad hoc Network can ease our life by making driving safe in near future. To make it successful efficient routing protocols need to be used for communication among vehicles. This communication can be direct within vehicles and can be through road side units (RSUs). In this paper we are exploiting the AODV, DSR and DSDV routing protocols by comparing their performances with respect to th...

Connectivity and cooperation are considered important prerequisites to automated driving, as they crucial elements in increasing the safety of future vehicles their full integration overall transport system. Although many European Member States, part C-Roads Platform, have implemented still implementing Road-side Units (RSUs) for Cooperative Intelligent Transportation Systems (C-ITS) within pil...

The Networks of vehicles moving on the road are considered as Vehicular Ad Hoc Networks (VANETs). The relative speed of the vehicles may be up to 300 km/hr and the number of nodes is very high. In Vehicular Ad Hoc Networks (VANETs) the nodes movement is bounded to road topology. In VANET the link breakage can be avoided with the help of the mobility pattern knowledge for neighbor nodes. In this...

Vehicular adhoc networks (VANETs) are relegated as a subgroup of Mobile adhoc networks (MANETs), with the incorporation of its principles. In VANET the moving nodes are vehicles which are self-administrated, not bounded and are free to move and organize themselves in the network. VANET possess the potential of improving safety on roads by broadcasting information associated with the road condit...
