Inter-vehicular wireless networks have become more popular during the last years, due to their possibility to realize new, interesting and useful applications for the driver. Data transmission in inter-vehicular environment is more challenging with respect to data transmission in static wireless networks. For this reason, theoretical and empirical studies are still in progress. This talk will present an experimental study on the performance of Voice over IP (VoIP) transmissions in inter-vehicular environment for the development of safety applications.

A fundamental question to address is what levels of traffic fluctuations may justify the deployment of reconfigurable optical networks. Based on a flow model, this talk provides a preliminary answer for IP/MPLS over WDM networks.

TCP is being used extensively as the Transport Layer Protocol for handling traffic flow through the current networks. With wireless connectivity becoming more popular, the effects of wireless communication on the Transport protocol are interesting to study.The proposed solution aims at improving the TCP performance while operating over wireless channels. A simulation based study is carried out comparing performances over the conventional Transport Protocol. The study shows that using the proposed technique, we can achieve higher throughput levels against the plain protocol. The wireless access scheme is chosen from the IEEE 802.11 system operating in the Ad-hoc mode.
