“…An important challenge in the VANET domain is the scalability of data dissemination, which has been identified in numerous independent studies [4][5][6][7][8][9][10][11]. The goal of this paper is to realize a solution that overcomes this challenge, enabling scalable data dissemination in V2V and V2I communication.…”

“…As a result, delays and packet losses increase to a level where the VANET cannot be applied for safety applications anymore. In [4][5][6][7][8][9][10][11], the hidden node problem ( Figure 1) is identified as one of the main drivers behind the performance decrease. The IEEE 802.11p MAC relies on a technique called carrier sense multiple access with collision avoidance (CSMA/CA) to coordinate transmissions on the wireless channel in a distributed manner.…”

An important challenge in the domain of vehicular ad hoc networks (VANET) is the scalability of data dissemination. Under dense traffic conditions, the large number of communicating vehicles can easily result in a congested wireless channel. In that situation, delays and packet losses increase to a level where the VANET cannot be applied for road safety applications anymore. This paper introduces scalable data dissemination in vehicular ad hoc networks (SDDV), a holistic solution to this problem. It is composed of several techniques spread across the different layers of the protocol stack. Simulation results are presented that illustrate the severity of the scalability problem when applying common state-of-the-art techniques and parameters. Starting from such a baseline solution, optimization techniques are gradually added to SDDV until the scalability problem is entirely solved. Besides the performance evaluation based on simulations, the paper ends with an evaluation of the final SDDV configuration on real hardware. Experiments including 110 nodes are performed on the iMinds w-iLab.t wireless lab. The results of these experiments confirm the results obtained in the corresponding simulations.
