Scheduling in VANET

Abstract

A Vehicular Ad-Hoc Network, or VANET, is a subset of Mobile ad-hoc network, to provide communications among nearby vehicles and between vehicles and nearby fixed infrastructure, usually referred as Road Side Unit (RSU). Data communication on the roads is becoming further interesting, as the number of vehicles equipped with computing technologies and wireless communication devices increase (OBU). Recently VANET focuses on public safety, enhance driving and infotainment applications which requires lot more data exchange between vehicle and RSU. When many vehicles want to access data from RSU or other vehicles, service scheduling becomes an important issue. In this thesis, I have focused on the problem of static periodic broadcast and suggested dynamic periodic broadcast scheduling. The proposed protocol can increase service ratio in terms of packet delivered ratio with less message traffic (i.e. number of duplicate messages received by individual vehicle is less). Simulation result shows that proposed broadcast scheduling protocol outperforms the conventional static periodic broadcast protocol in terms of packet delivery ratio and number of duplicate message receive by vehicle. In this work real time traffic and deadline are the main concern for scheduling.
