Vehicular Ad Hoc Networks (VANETs) have recently emerged as an effective tool for improving road safety through the dissemination of warning messages among vehicles. The envisioned applications, as well as some inherent VANET characteristics such as highly dynamic topology, frequently disconnected network, and different and dynamic network density, make data dissemination quite a challenging task. Several approaches for data dissemination using short-ranged communication techniques have been proposed, however data dissemination using traditional architecture has a number of problems such as broadcast storm, network partition, and temporal network fragmentation. The project aims to develop communication protocols that takes advantage of the best features of currently available communication technologies and provide services that are not likely to be implemented through the technologies individually. Thus, the integration of different wireless technologies should be considered to solve or minimize critical problems during the data dissemination, which is a major task in VANETs.
