Vehicle-to-Infrastructure (V2I) communications are increasingly supporting highway operations such as electronic toll collection, carpooling, and vehicle platooning. In this paper we study the incentives of strategic misbehavior by individual vehicles who can exploit the security vulnerabilities in V2I communications and impact the highway operations. We consider a V2I-enabled highway segment f...

Congestion on the roads is a key problem to deal with, which wastes valuable time.. Due to high mobility rate and relative speed link failure occur very often. VANET is used to tackle the problem of congestion, and make decisions well in advance to avoid traffic congestion. In this paper we proposed a solution to detect and control the traffic congestion by using of both (V2V) and (V2I), as a r...

Many Driver Support Systems in future vehicles will rely on wireless communication. This wireless communication can be divided into two categories: Vehicle-toVehicle (V2V) and Vehicle-to-Infrastructure (V2I). V2V is often used for vehicles to exchange information of a local nature, e.g. co-operative following or collision avoidance. V2I can be used as ’smart road signs’, access to back-end netw...

The Internet of Things is a new paradigm in which objects in a specific context can be integrated into traditional communication networks to actively participate in solving a determined problem. The Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) technologies are specific cases of IoT and key enablers for Intelligent Transportation Systems (ITS). V2V and V2I have been widely used t...

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...

It is foreseen that vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems will be deployed in the next decade. Data security is an enabler for V2V and V2I communication, because the authenticity, integrity and confidentiality of exchanged network traffic must be guaranteed, especially since these messages will certainly be used for safety applications. Furthermore, ...

Majority of the applications used in defense are voice, video and data oriented and has strict QoS requirements. One of the technologies that enabled this is Asynchronous Transfer Mode (ATM) networking. Traditional ATM networks are wired networks. But Tactical networks are meant to be mobile and this implies the use of radio relays for Vehicle-to-Infrastructure (V2I) and Vehicle-to-Vehicle (V2V...

For any network Q; one may consider the zero-sum search game (Q) in which the (minimizing) Searcher picks a unit speed path S (t) in Q; the Hider picks a pointH inQ; and the payo¤is the meeting time T = min ft : S (t) = Hg : We show …rst that ifQ is symmetric (edge and vertex transitive), then it is optimal for the Hider to pickH uniformly inQ; so that the Searcher must follow a Utilitarian Pos...

In this communication, a low-cost circularly polarized wire antenna exhibiting improved gain performance for Dedicated Short Range Communications (DSRC), vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications is presented. The proposed antenna comprises a Y-shaped quarterwavelength monopole antenna surrounded by two iterations of eight conductive arched walls acting as para...

Vehicular Ad-Hoc Networks (VANETs) have a highly dynamic network topology due to the constant and rapid movement of vehicles. Therefore, communication in VANETs is mostly affected with disruptions and delays as a result of network disconnections and partitions. Moreover, increasing the geographical coverage area for data dissemination while keeping the data-delivery delay low is a challenge. Th...
