“…Multi-hop broadcast in VANET mainly supports two types of broadcast applications. One type is safety applications such as Collective Collision Avoidance (CCA) where in the event of an emergency an alert message is propagated as quickly as possible into oncoming traffic [13]. Broadcast protocols for these applications are usually designed to propagate messages in one or two directions with high reliability and minimum latency.…”

Vehicular networking applications often use multi-hop wireless broadcasting as a primary data dissemination mechanism. Therefore, protocols that efficiently and thoroughly propagate application data while adapting to a wide range of network density, vehicle distribution pattern, channel quality, and other conditions are critical for vehicular communications. Here, we design the Statistical Vehicular Broadcast (SVB) protocol to efficiently distribute data via multi-hop broadcast in vehicular networks.First, we present an automated optimization technique for the design of threshold functions in statistical broadcasting methods. Next, we compare and analyze known statistical techniques, including different fundamental methods, assessment delay algorithms, and failsafe mechanisms. All combinations of these techniques are given threshold functions optimized using the proposed automated procedure then are evaluated in a wide range of simulations. High-level statistical design principles and recommendations are established based on analysis of these results. Finally, we apply those principles to design SVB. It is evaluated in JiST/SWANS and is shown to achieve a high target reachability level while consuming less bandwidth than similar protocols across urban and highway vehicular networking scenarios.

“…In the literature, Time To Collision (TTC) has been adopted as a commonly used metric for predicting a collision, whether by using V2V communication [7] and [6] or other sensors such as radar or camera [4]. One thing common to this research is the use of a sensor to estimate the location, speed and sometimes heading of nearby vehicles, and form an estimate the TTC using a vehicle motion model.…”

The detection and avoidance of vehicle collisions is an important area of research in the field of Intelligent Transportation Systems (ITS). Time To Collision (TTC) is widely used as an indicator of impending collisions between two vehicles. This is generally calculated using sensors and/or V2V communication to determine the state of nearby vehicles, and by performing a future projection of the state to estimate a collision. This paper introduces a technique using a digital map to incorporate features of the road environment into the vehicle model, providing constraints on the potential vehicle motion. This model provides an estimate of the 'real' minimum distance between vehicles given the road environment, the likely mode of interaction, and an estimate of the Time To Interaction (TTI) between a pair of vehicles. The metrics provide a high level estimate regarding the potential for future vehicle interactions, which can be augmented by incorporating additional measures of estimated driver intention. The metrics can also be incorporated into low level collision avoidance systems as a filter for vehicles that should not be considered a threat due to map constraints, which reduces the likelihood of false positives.

“…The main components of the UMTS network are radio network controller, BST, serving general packet radio service (GPRS) support node (SGSN), and gateway GPRS support node (GGSN) . By contrast, VANET is used for short‐range but high‐speed communication from vehicle to vehicle and from vehicles to the infrastructure (V2I) .…”

SUMMARYIntegrating vehicular ad hoc network (VANET) and universal mobile telecommunication system (UMTS) could be a promising architecture for future machine-to-machine applications. This integration can help vehicles have steady Internet connection through the UMTS network and in communicating with other vehicles. However, dead spot areas and unsuccessful handoff processes caused by the high speed of vehicles can disrupt the implementation of this kind of architecture. In this paper, a new simplified gateway selection (SGS) scheme for multihop relay in a VANET-UMTS integration network is proposed. The proposed scheme extends the coverage or/and calming of the frequent handoff process and allows vehicles to continue to be connected to the UMTS infrastructure network. An integrated simulation environment that combines VanetMobiSim and NS2 is used to simulate and evaluate the proposed scheme. The simulation results show that the SGS scheme performed better when it was implemented with ad hoc on a demand distance vector routing and destination-sequenced distance vector routing protocols. Furthermore, the SGS scheme is compared with other cluster-based gateway selections used in the previous works. The results show that our SGS scheme outperforms other cluster-based gateway selections scheme in terms of selection delay, control packet overhead, packet delivery ratio, and overall throughput.
