Table-driven bus-based routing protocol for urban vehicular ad hoc networks

Abstract

Vehicular Ad Hoc Networks (VANETs) have attracted increasing interest over the past decade, but the design of an efficient routing method for VANETs is still a challenging task. Via analyzing characteristics of urban VANETs (such as the heterogeneous vehicular types and the impact of traffic lights), we believe that buses can be used as the mobile backbone of VANETs to aid data transmissions. In this paper, we propose a table-driven bus-based routing protocol to lighten the control of packet delivery and reduce the average delay. Simulation results demonstrate a significant improvement in terms of delivery ratio and average delay over traditional routing protocols.
