This paper presents Distributed Rate Control for VANETs (DRCV), a distributed light-weight congestion control algorithm tailored for safety messages. DRCV monitors and estimates channel load and controls the packet rate of outgoing periodic packets. A new approach called Fast Drop is adopted to promptly drop the rate of periodic packets when event-driven(More)
—Beacon and event-driven warning messages are two important messages that are used by many Intelligent Transportation Systems (ITS) applications for improving road safety and traffic efficiency. Beacon messages are regularly broadcast by each vehicle to notify other vehicles of its presence and its status. Event-driven warning messages are emitted when a(More)
In this paper, we propose a novel solution for usage of the Network Mobility Basic Support protocol in vehicular ad hoc networks. The solution adopts geographical routing as a sub-IP ad hoc routing protocol and applies a standard NEMO Mobile Router on top. As a result, Internet access enhanced with IP mobility support is available via a multi-hop path(More)
—In this paper, we propose a novel mechanism for application of an IPv6 automatic address configuration technique to vehicular ad-hoc networks. The solution consists of combining standardized IPv6 schemes with geographic routing function-alities, which enables the matching of geographically-scoped network partitions to single IPv6 multicast-capable links.(More)
In this article we make a thorough characterization and evaluation of the solution standardized by the European Telecommunications Standards Institute for IPv6 transmission of packets over geographical location aware vehicular networks. In particular, we focus on IPv6 address auto-configuration, one of the required pieces to enable Internet connectivity(More)
