Abstract:
The challenges Intelligent Transportation Systems (ITS) address have only increased in time as, along with fast and cost-effective route planning, environmental sensibilities are nowadays also prominent. Currently, many ITS related studies focus on studying Car-to-Car (C2C) and Car-to-Infrastructure (C2I) communications in Vehicular Ad-hoc Network (VANET) environments. The utilization of such infrastructure-less and flexible topology networks poses several challenges for the routing mechanism aiming to achieve effective and efficient message delivery, specifically through broadcasts. This paper presents a new broadcast-based message delivery approach termed the Traffic Message Delivery Algorithm (TMDA) optimized for a city-based VANET setting. TMDA considers urban traffic travelling patterns and has been designed to exploit the route properties of different vehicle types such as cars and buses. In the case of the latter, TMDA adjusts its message propagation strategy so that bus routes, which intuitively involve elements (buses) with predictable routes, help propagate broadcast messages to a whole region which may otherwise have been disconnected. We investigate and compare the communications performance of vehicle groups under TMDA against other broadcast protocols through a set of experiments using NS-2 to simulate communications and SUMO to create representative mobility patterns. The simulation outcomes show that TMDA outperforms its competitors in efficiency and reliability while avoiding the deteriorating effects of a broadcast storm.
