“…It is based on the IEEE 802.11p standard. The general idea of disseminating emergency messages in VANETs has been already presented in [11], focusing on routing of emergency messages. However, we focus on how the current eCall functionality can be enhanced using C2C and C2I communication concepts.…”

The Pan-European eCall system recommended by the European Commission will be available in new vehicles starting in 2015. It will provide automated emergency call functionality for equipped vehicles using mobile communication. However, we show that the eCall's design has limitations. Therefore, we propose extensions for an emergency message dissemination system. We show that these extensions cannot easily be realized using the eCall's communication facilities and provide a concept using Car-to-Car (C2C) and Car-to-Infrastructure (C2I) communication. A prototypical implementation validates our concept to improve rescue information and to be more extensible with respect to the standard eCall.

“…For example, CRCA [16] is a limited-scope-broadcast based warning systems that only generates warnings in the event of emergency brake and potential intersection collisions that it identifies in advance using a prediction-based algorithm. ODEM [20] is another road-safety system that gets activated when an accident takes place. It uses opportunistic propagation of accident information to hospitals, police stations and fire stations Although limited-scope-broadcast reduces the wastage of network capacity compared to flooding-based schemes, it does not stop the flooding of the immediate locale of the source.…”

Abstract-An Accident Warning System (AWS) is a safety application that provides collision avoidance notifications for next generation vehicles whilst Vehicular Ad-hoc Networks (VANETs) provide the communication functionality to exchange these notifications. Despite much previous research, there is little agreement on the requirements for accident warning systems. In order to build a practical warning system, it is important to ascertain the system requirements, information to be exchanged, and protocols needed for communication between vehicles. This paper presents a practical model of an accident warning system by stipulating the requirements in a realistic manner and thoroughly reviewing previous proposals with a view to identify gaps in this area.

“…For example, if a traffic accident occurred, by using message broadcasting in VANETs, authorities and medical assistance could be notified of the exact location and severity of the accident in a timely and effective manner. Other vehicles around the accident site could also be notified to avoid a possible traffic jam . In addition, some entertainment services , such as online videos and games are accessible through VANETs to offer passengers a more comfortable experience on their trip.…”

In the recent years, we are witnessing a growing interest into the design of smart vehicles and smart roads for Intelligent transportation systems. Vehicles as part of the Internet of Things should provide to the driver and passenger with a variety of services using efficient gateway discovery mechanism while maintaining a certain level of security and authentication to avoid potential malicious attacks. In this paper, we propose a secure hybrid adaptive gateway discovery and communication protocol for smart vehicular networks, which we refer to as SEGAL. Our proposed SEGAL protocol is based upon building a secure clustered vehicular network, and permits the exchange of gateway discovery messages through authenticated clusterheads and cluster members. We shall present the design of our protocol, and describe how it can overcome the possible malicious attacks that might harm the network. Then, we report its efficiency and scalability using an extensive set of simulation experiments using Ns‐2 simulator. Our results indicate that the proposed SEGAL protocol is scalable while achieving high success rate, low response time and dropping rate. Copyright © 2016 John Wiley & Sons, Ltd.
