Paper Details

A Vehicular Ad hoc Network (VANET) is a form of Mobile Ad hoc Networks, to provide communication betweenvehicles. The main intension of VANET is safety and comfort for users. The successful distribution of critical message invehicular ad hoc networks can create a variance between life and death. To get the life-saving goals, emergency datadistribution needs timely and lossless medium access in vehicular ad hoc networks. However there previous medium accesscontrol (MAC) protocol that providing priority medium access in the previous work. The MAC protocol target onarithmetical importance for providing unicast flows instead of strict importance for separate pockets. So in this approach anew MAC mechanism to find this problem with its “Novel Pulse-Based Control:” scheme, the implemented MAC schemeunderstands strict packet-level importance arrangement for emergency packets in a fully transferred way. Using thismechanism the implementing mechanism supports different level of strict priority for immediate packets. The completesimulation outcomes in this approach shows the efficiency of the implemented MAC mechanism in helping critical messagesin vehicular ad hoc networks. And also in this work we analyzing of vehicular networks. In vehicular networks mobile usersin vehicles can admission the web and enjoy different aspects like Voice over IP (VoIP) and online streaming video. To gainbetter Quality of Service, we need to suitably place gateway to communicate mobile nodes to the web or any other datanetworks. To rectify the problems of QoS, in this paper analyzing that how to optimally place gateway in vehicular networks.And also reducing minimum number of hops from Access points to Gateway. With is work we can reduce communicationdelay.
