The Delay Tolerant Networks (DTN) approach is considered the best strategy to address the specific issues of the VANETs, namely high mobility, variable node density or frequent radio obstacles. Several protocols have been proposed for DTNs, being the epidemic routing (and variations of it) the most representative protocol. Nevertheless, the availability of navigation systems, thanks to which each...
Due to the increasing popularity of mobile devices and the growing development of wireless networks, nowadays automobiles are able to communicate among them and with the infrastructure using different wireless technologies, thus improving not only communications but also safety on the roads. In order to improve communications by maintaining the Quality of Service (QoS) required by applications (e...
Nowadays our vehicles incorporate multiple sensors that collect information not only about speed or fuel consumption, but also about weather (rain sensors), road state (ESP sensors), etc. Achieving a distributed traffic monitoring system that combines all this information gathered by different vehicles is a challenging task. In particular, we consider that vehicular ad-hoc networks (VANETs) are particularly...
Communications among vehicles and their capability of accessing cloud services is about to become a reality due to the ongoing development of sophisticated On-Board Units, which are powered by advanced processors, GPS devices, sensors, and multiple wireless access technologies such as Wi-Fi, WiMAX and UMTS. Users within vehicular networks will be able to access content from the Internet at high speeds...
