Design and performance evaluation of data dissemination and hovering information protocols for vehicular ad hoc networks (VANETs)

Abstract

Robust and efficient communication protocols for Vehicular Ad Hoc Networks (VANETs) are still an open topic in the literature. Because of that, our attention has been gathered by the Data Dissemination and the Information Hovering protocols for VANETs. For most of the VANETs' applications the data dissemination is a crucial process. Also, for many of them the availability of information over some time in a bounded region, or a Hovering Information protocol, is a key feature. Hence, in this thesis we are proposing two data dissemination protocols and one information hovering protocol for VANETs. Furthermore, we evaluate the performance of these protocols by conducting an extensive simulation experiment and comparing their effectiveness with other relevant protocols in the literature. As could be seen in the results shown in the thesis, the proposed protocols outperform the other schemes regarding various evaluation parameters as Delivery Ration, Total number of rebroadcast packets, etc.
