Reliable Freestanding Position-Based Routing in Highway Scenarios

Abstract

Vehicular Ad Hoc Networks (VANETs) are considered by car manufacturers and the research community as the enabling technology to radically improve the safety, efficiency and comfort of everyday driving. However, before VANET technology can fulfill all its expected potential, several difficulties must be addressed. One key issue arising when working with VANETs is the complexity of the networking protocols compared to those used by traditional infrastructure networks. Therefore, proper design of the routing strategy becomes a main issue for the effective deployment of VANETs. In this paper, a reliable freestanding position-based routing algorithm (FPBR) for highway scenarios is proposed. For this scenario, several important issues such as the high mobility of vehicles and the propagation conditions may affect the performance of the routing strategy. These constraints have only been partially addressed in previous proposals. In contrast, the design approach used for developing FPBR considered the constraints imposed by a highway scenario and implements mechanisms to overcome them. FPBR performance is compared to one of the leading protocols for highway scenarios. Performance metrics show that FPBR yields similar results when considering freespace propagation conditions, and outperforms the leading protocol when considering a realistic highway path loss model.

“…A reliable freestanding position-based routing algorithm (FPBR) for highway scenarios in the context of Vehicular Ad Hoc Networks (VANETs) is proposed in [19]. FPBR performance is compared to one of the leading protocols for highway scenarios showing that FPBR yields similar results, when considering free space propagation conditions, and outperforms the leading protocol when considering a realistic highway path loss model.…”

Robust Content Broadcasting in Vehicular Networks

“…Vehicular ad hoc networks (VANETs) [1,2] have been specifically introduced to cope with the aforementioned purposes. VANETs are mobile ad hoc networks that support the communication among neighbor vehicles and can be extended to support communication between vehicles and infrastructures placed in the surrounding environment.…”

An Infrastructureless Approach to Estimate Vehicular Density in Urban Environments

“…Though traffic safety has been the primary motive for the development of these networks [3–5], VNs also facilitate applications such as managing traffic flow, monitoring road conditions, environmental protection, and mobile infotainment applications [6–8]. Most of these applications could be more efficient if the protocols involved become aware of the density of vehicles at any given time [9], being able to adapt their behavior according to this factor.…”
