In this paper, we address the reliable alarm message dissemination in Vehicular Ad hoc NETworks (VANETs) environment. We study various techniques to disseminate emergency data, after a car crash, within a group of vehicles. We consider a trajectory-based data dissemination technique to perform broadcast flooding task optimization, and compare it with a pure flooding scheme. For the evaluation, we...
The past few years have seen an increasing interest in the development of vehicular ad hoc networks resulting in many routing protocols proposals. This paper presents the results of a detailed performance evaluation of three of these protocols selected from different categories: geographic routing (i.e., GPSR), geographic opportunistic routing (i.e., GOSR), and trajectory based routing (i.e., SIFT)...
