Distance is a key measure when implementing timer-based dissemination protocols in Vehicular Ad-hoc Networks (VANets). In which the transmission is deferred proportional to distance, aiming to order vehicles transmission, such that the farthest vehicle gets the highest opportunity to relay the message. This will ensure long hops along the road to speed up the dissemination and cover more nodes. However,...
Smart vehicles have been capturing increasing attention as major providers of ubiquitous information services. In this paper, we propose a solution to enable expedited and cost-effective access of road information for vehicles as information requesters. The proposed caching-assisted data delivery with mobile requesters (CADD-MR) scheme employs caching on the data delivery path for handling later interests...
Cellular networks are particularly suitable for the provision of vehicular online services due to their high coverage rates. The network dynamics and the mobility of the vehicle lead to frequent changes in the communication properties. Many vehicular application do not deal well with unexpected changes in conditions. In this paper we present our approach to provide vehicles with context data about...
In VANETs, vehicle-to-vehicle communication is a challenge due to the fast topology changing, frequent disconnections, and highly variable traffic densities. This paper describes a Trajectory-based data Forwarding scheme with future Neighbor Prediction (TFNP) in autonomous driving vehicular environments. The most important characteristic of the environments is that the prediction for future position...
Several traffic evaluation and congestion detection protocols have been proposed in the literature for the vehicular networks. These protocols gather and analyze the basic traffic data of all traveling vehicles at each area of interest to obtain the vehicular traffic evaluations. All vehicles should be equipped by wireless transceiver in order to send and receive the packets of their traffic data...
