Improving Message Delivery In Vehicular Ad-Hoc Networks

Road traffic information has been a primary source for traffic management, user services and other systems that enable road congestion prevention and control; however, road traffic information has not been adequately exploited as a part of the design for wireless communication network. In vehicular ad-hoc networks, the protocol design must consider the dynamic nature of the topology and the probability of available alternate routes for wireless routing. The information provided by either the road itself or the activities on the road can help to void common issues such as broadcast storms, hidden node problems and lost data caused by an increase in road traffic density or sparse road traffic respectively. Routing protocols must therefore be able to dynamically adjust to the current road traffic information. In order to improve message delivery in vehicular ad-hoc networks, this project proposes a collaborative process of utilizing real time road traffic information and route knowledge to enhance routing decisions in order to maximize packet delivery ratio and reduce delays in transmission.
