Directed information dissemination in vehicular ad-hoc networks

Directed information dissemination in vehicular ad-hoc networks

In this article, we utilize the idea of multipoint relays (MPRs) found in literature [2] to propagate accident information in a restricted way (e.g., only backwards). We devise an algorithm to identify MPRs that are geographically situated behind a particular node using only its neighbor table, and speed information of the neighboring vehicles. With the identification of the backward MPRs, it i...

Speed Adaptive Information Dissemination in Vehicular Ad-hoc Networks

yTraffic Information Dissemination in Vehicular Ad Hoc Networks

Today, cars are equipped with all kind of on-board sensors and microcomputers that are able to measure geolocation, speed, tire pressure, raindrops on the windshield, etc., and based on these information Intelligent Transportation Systems (ITS) are built. The ITS applications are intended to ease the everyday life of drivers by reducing the risk of accidents, improving safety, increasing road c...

Emergency Information Dissemination in Vehicular Ad Hoc Networks

The main goal of inter-vehicle communication technology is to provide the drivers with more information regarding the surroundings than they can visually perceive. A Vehicular Ad-Hoc Network, or VANET, is one such technology that uses moving vehicles as nodes in a network to create a wireless ad hoc network. Many applications in VANETs are based on dissemination of information to the drivers ab...

Congestion Reduction Using Ad-Hoc Message Dissemination in Vehicular Networks

Vehicle-to-vehicle communications can be used effectively for intelligent transport systems (ITS) and location-aware services [1]. The ability to disseminate information in an ad-hoc fashion allows pertinent information to propagate faster through the network. In the realm of ITS, the ability to spread warning information faster and further is of great advantage to the receivers of this informa...
