Geo-Opportunistic Routing for Vehicular Networks

Free registration required

Executive Summary

Road topology information has been recently used to assist geographic routing in urban vehicular environments to improve the overall routing performance. However, the unreliable nature of wireless channels due to motion and obstructions still makes road topology assisted geographic routing challenging. This paper begins by reviewing conventional road topology assisted geographic routing protocols and investigates the robust routing protocols that address and help overcome the unreliable wireless channels.
