“…The work by [9] propose a multi-hop broadcast protocol called Fast Broadcast that reduces the time to propagate a message and reduces the total number of hops to cover a portion of the road. The scheme estimates forward and backward transmission ranges, computed using two rounds of transmission ranges (current-turn and last-turn).…”

Abstract-A primary goal of intelligent transportation systems (ITS) is to improve road safety. The ability for vehicles to communicate is a promising way to alleviate traffic accidents by reducing the response time associated with human reaction to nearby drivers. In addition the limitations of standard driving can be overcome by providing drivers with instantaneous information about complications up ahead. Shockwaves, induced by vehicle speed differentials, are a typical mobility pattern that occurs with the formation and propagation of vehicle queues. These induce sudden braking and increase the occurrence of traffic incidents. In this paper, we investigate safety applications in highways with shockwave mobility and different lane configurations in vehicular ad hoc networks (VANET). We evaluate the performance of multi-hop broadcast communication using the ns-2 simulator with vehicles following a shockwave mobility pattern in fully-connected traffic streams. We propose mechanism to improve broadcast reliability using dynamic transmission range that leverages our understanding of fundamental traffic flow relationships.

Abstract-We investigate here the following fundamental question -how can we achieve a high reachability while minimizing the inherent effects of high transmission power for a beamforming-based broadcast scheme in multihop wireless networks? To address this challenge, this paper proposes a fully distributed scheme that allows nodes to set dynamically their transmission range based on their local densities and the distance to the destination. The efficiency of this technique is studied first in a vehicular environment, considered as a particular scheme of a multihop wireless network, and demonstrated in terms of implicated nodes'ratio, power transmission gain and probability of transmission success using real road networkbased simulations. Furthermore, the proposal is evaluated using a simplified node distribution scheme, suitable to wireless adhoc networks, and an analytical model is derived to calculate the transmission area. This model allows capturing the propagation shape of the forwarding zone. Extensive simulations confirm the merit of the analytical expressions.

“…It is well known that a slow broadcast delivery is often due to a non-optimal number of hops experienced by a message to cover all the involved cars and, more in general, to an excessive number of vehicles that try to simultaneously forward the message [6,8,9,10,13].…”

Abstract-As the technology available on cars is increasing, a wide range of applications, from safety to entertainment, are becoming available for this scenario. Many of these applications involve interactive multi-hop broadcast of messages over a certain area-of-interest. To this aim, specific solutions have been proposed to deal with the high mobility and density of a vehicular network scenario. In particular, we developed a simple, yet effective, solution for allowing cars to estimate their communication range through including few parameters in exchanged application messages. Then, this range estimation is exploited to reduce the number of hops and the delay required by a broadcast message to reach all the vehicles in the area-ofinterest. Since so far the evaluation of our solution has been focused on simulations, we have now created a real testbed. Here, we report on results achieved through this real testbed, showing that they confirm the efficacy of our solution in estimating vehicles' transmission range and choosing the most appropriate forwarder for transmitted messages.
