Middleware architecture for intelligence in vehicular safety over VANET (InVANET)

TL;DR: The aim of this research work is to focus on design of a middleware architectural model for providing safety in “high-speed mobile” vehicles forming a network over IEEE 802.11 VANET nodes.
Abstract: The abstract is to be in Vehicular ad-hoc networks (VANET) belonging to family of ad-hoc uses IEEE 80211p standard which have received considerable attention in many vehicular projects and industry groups VANETs are a special kind of mobile Ad-Hoc networks where wireless-equipped (road-side) vehicles form a network with no additional infrastructure While many communication scenarios exist for these networks, InVANET project focuses on the application to improve vehicular safety by taking into account the physiological and ecological context-aware / sensitive parameters to increase driver convenience The aim of this research work is to focus on design of a middleware architectural model for providing safety in “high-speed mobile” vehicles forming a network Even though a number of passive safety approaches exist, incorporating active safety (intelligence) is challenging part of this work This research paper discusses on design, functionality and working architecture of InVANET and the test-bed is being simulated over IEEE 80211 VANET nodes

Abstract: This document specifies a Dynamic Host Configuration Protocol Option for the coordinate-based geographic location of the client. The Location Configuration Information (LCI) includes latitude, longitude, and altitude, with resolution indicators for each. The reference datum for these values is also included. [STANDARDS-TRACK]

TL;DR: In two experiments, two experimental types of road-edge delineation, one with continuous and one with dashed edgelines, were compared with two control roads, one without lines and another with only a dashed line on the road axis as discussed by the authors.
Abstract: Drivers driving on lower-class Dutch rural roads without any delineation more frequently drift off the road with their right-hand side tires, invoking damage to the pavement edge or even ending in an accident. In two experiments, two experimental types of road-edge delineation, one with continuous and one with dashed edgelines, were compared with two control roads, one without lines and one with only a dashed line on the road axis. The first experiment consisted of non-obtrusive video recordings of passing traffic. Vehicle position on the experimental roads was found to be more to the road's centre than on the control roads. The second experiment was a driving test with an instrumented vehicle. Again, it was found that vehicle lateral position was more central on the experimental roads, especially during darkness. Driving speed increased on the experimental roads, compared with the unlined control road, but speed was lower than on the axis-lined control road. Subjectively rated effort was higher for the unlined control road than for the three other roads. Subjects preferred the edgelined roads to the unlined control road, but not to the axis-lined control road. Edgelines may provide a simple and effective way to induce a more favourable lateral position on rural roads without having negative effects on subjective appraisal, driving performance and mental workload.

TL;DR: It was concluded that edge-lines may provide a simple and effective way of inducing a more favourable lateral position on rural roads without having negative effects on subjective appraisal, driving performance or mental workload.
Abstract: When driving on lower-category Dutch rural roads without any delineation, drivers are likely to drift off the road with their right-side wheels, thus incurring damage to the pavement edge or even leading to accidents. In two experiments, two types of road-edge delineation, with continuous or dashed edge lines, were compared with two control roads without lines or with only a dashed line on the road axis. The first experiment consisted of non-obtrusive video recordings of passing traffic. Vehicle position on the experimental roads was more to the road's centre than on the control roads. The second experiment was a driving test with an instrumented vehicle, during daytime lighting and during darkness. Again, vehicle lateral position was more central on the experimental roads, especially during darkness. Subjects could safely pass oncoming vehicles. Driving speed increased on the experimental roads compared with the unlined control road, but not beyond speeds found on the axis-lined control road. Driver's mental effort while driving over the experimental roads did not differ from the effort while driving over the control roads. Subjectively rated effort was higher for the unlined control road than for the three other roads. Subjects preferred the edge-lined roads to the unlined control road, but not more than the axis-lined control road. It was concluded that edge-lines may provide a simple and effective way of inducing a more favourable lateral position on rural roads without having negative effects on subjective appraisal, driving performance or mental workload.

TL;DR: This Space-Elastic Model of real-time communication is the first to directly address adaptation in the space domain to guaranteereal-time constraints within the defined proximities only.
Abstract: Applications of inter-vehicle and vehicle-to-roadside communication that make use of vehicular ad hoc networks (VANETs) will often require reliable communication that provides guaranteed real-time message propagation. This paper describes an event-based middleware, called RT-STEAM. Unlike other event systems, RT-STEAM does not rely on a centralized event broker or look-up service while still supporting event channels providing hard real-time event delivery. RT-STEAM event filtering can be based on subject, content and/or proximity. To guarantee real-time communication, we exploit proximity-based event propagation to guarantee real-time constraints within the defined proximities only. The proximity within which real-time guarantees are available is adapted to maintain time bounds while allowing changes to membership and topology, typical of VANETs. This Space-Elastic Model of real-time communication is the first to directly address adaptation in the space domain to guarantee real-time constraints.

Abstract: Applications of inter-vehicle and vehicle-to-roadside communication that make use of vehicular ad hoc networks (VANETs) will often require reliable communication that provides guaranteed real-time message propagation. This paper describes an event-based middleware, called RT-STEAM, designed to meet these requirements. Unlike other event systems, RT-STEAM does not rely on a centralized event broker or look-up service while still supporting event channels providing hard real-time event delivery. RT-STEAM event filtering can be based on subject, content and/or proximity. Proximity filters define geographical areas within which events are delivered. To guarantee real-time communication, we exploit proximity-based event propagation to guarantee real-time constraints within the defined proximities only. The proximity within which real-time guarantees are available is adapted to maintain time bounds while allowing changes to membership and topology as is typical of VANETs. This Space-Elastic Model of real-time communication is the first to directly address adaptation in the space domain to guarantee real-time constraints.
