“…Our probability functions are simple but effective in providing adaptivity to density. Therefore, the comparison of our approach with state of the art protocols DV-CAST [3] and Edge-Aware [4] in realistic traces, proved the efficiency of EpiDOL in terms of lower delay, higher throughput rates and better utilization of opposite lane relaying. The novelties of this work as following.…”

“…However, as a result of the redundant broadcasts there may be contentions and collisions in the shared wireless medium. VANET routing protocols mainly deal with two problems, broadcast storm and disconnected networks [4]. When high number of nodes start to disseminate their packets at the same time, it is highly probable that the collisions will occur.…”

“…To prove the efficiency of EpiDOL, we compared it with state of the art data dissemination protocols designed for VANET, namely Edge-Aware [3] and DV-CAST [4]. Edge-Aware is also an epidemic protocol that utilizes the GPS information.…”

“…Also, the proposed protocol is only compared with simple flooding protocol in a controlled scenario rather than realistic traces. DV-CAST [4] is a distributed broadcast protocol that utilizes opposite lane vehicles. By exchanging GPS information, every vehicle classifies its network as a well connected, sparsely connected or totally disconnected network.…”

Abstract. Vehicular ad-hoc networks (VANETs) aim to increase the safety of passengers by making information available beyond the driver's knowledge. The challenging properties of VANETs such as their dynamic behavior and intermittently connected feature need to be considered when designing a reliable communication protocol in a VANET. In this study, we propose an epidemic and density adaptive protocol for data dissemination in vehicular networks, namely EpiDOL, which utilizes the opposite lane capacity with novel probability functions. We evaluate the performance in terms of end-to-end delay, throughput, overhead and usage ratio of the opposite lane under different vehicular traffic densities via realistic simulations based on SUMO traces in ns-3 simulator. We found out that EpiDOL achieves more than 90% throughput in low densities, and without any additional load to the network 75% throughput in high densities. In terms of throughput EpiDOL outperforms the Edge-Aware and DV-CAST protocols 10% and 40% respectively.

“…Tonguz et al present in [16,17] a broadcasting algorithm that depends only on the local topology information and that is robust against different types of vehicular traffic conditions. It handles both, the disconnected network and the broadcast storm problem [18] in a completely distributed fashion.…”

In this work, we focus on vehicular ad hoc networks, also called VANETs, which are communication networks that devices (in this case vehicles) use to exchange messages in a distributed fashion, i.e., using no preexisting infrastructure. We first assess the feasibility of relying on a tree-based topology management structure for mobile ad hoc networks and in particular for VANETs. Next, we enhance DAGRS, an existing decentralized model for enabling distributed tree management and build BODYF on it, an efficient broadcast algorithm. Several broadcasting algorithms of the state of the art are implemented in order to compare the performance of BODYF. The approach is validated by simulation through three realistic scenarios located in Luxembourg city: the city center for both pedestrian and vehicles, and a highway environment. The comparison is made in terms of the coverage achieved by the broadcasting process as well as the complexity of the messages. DAGRS/BODYF approach outperforms other existing protocols in terms of both the number of devices reached and the network use.

Vehicular Ad Hoc Networks (VANETs) are the potential core of the Intelligent Transportation System (ITS) which aims to increase people safety and improve transportation efficiency. In this paper, we provide the first known taxonomy of VANET data communication protocols, based on road dimension, neighbor knowledge, acknowledgment, start of forwarding, competition to retransmit, vehicle connectivity, urgency, and message contents. The taxonomy provides fundamental blocks in VANET data communication protocols and help researchers better understand the details of each protocol. Further, the taxonomy helps in designing new protocols, by replacing one option by another from the same category. It also helps to understand various limitations of certain protocols, and the need to generalize these protocols and apply them in various VANET applications and scenarios. We also provide here a survey of recent data communication protocols, and a tutorial on how most of them work.
