“…Vehicle networks will not only improve the safety and the efficiency of the transportation system, but also assist communications in emergences such as planned evacuation [16] or unexpected disastrous failure of key infrastructure components (e.g., roadside unit support). When an emergence or infrastructure failure occurred, a secure and quick communication path to empower VNET in performing the above tasks are very important especially when potential human lives are involved.…”

Establishing trust in vehicular networks is a critical but also difficult task. In this position paper, we present a new trust architecture and model -Situation-Aware Trust (SAT) -to address several important trust issues in vehicular networks that we believe are essential to overcome the weaknesses of the current vehicular network security and trust models. Our model also strengthens the tie between Internet infrastructure. The new SAT includes three main components: (a) an attribute based policy control model for highly dynamic communication environments, (b) a proactive trust model to build trust among vehicles and prevent the breakage of the existing trust, and (c) a social network based trust system to enhance trust and to allow the set up of a decentralized trust framework when the vehicular network is under infrastructure failure or under attacks.

“…In [7], the authors used related mechanisms in VANET to reduce the traffic information for spatio-temporal traffic, and the proposed system provided solutions to clear the path for emergency vehicles. But the authors didn't discuss the situation of the dynamic traffic, and the path from the source to destinstion is just traced by the digital map in emergency vehicles.…”

Emergency service vehicles need safety and fluent paths to save time. In this paper, a centralized traffic control mechanism is proposed for the evacuation of vehicles that drive toward the dedicated path of the emergency vehicles (EV), e.g. Ambulance, Fire Engines, Police Cars, etc, using the Dedicated Short Range Communications (DSRC) protocol. In our proposed mechanism, a centralized server is used to monitor and control all traffic information to support real time traffic information and services for emergency vehicles, and the centralized server also calculates the shortest path for emergency vehicles to pass by. If the approaching information of emergency vehicles is not announced in advance to other vehicles that will obstruct the approaching path of emergency vehicles, it will cause the traffic muddle on the road and increase the delayed time for emergency vehicles. Thus, we also propose a data dissemination scheme to transmit the warning messages to other vehicles that will obstruct the approaching road of emergency vehicles. In our experiment, we will exhibit the performance of our proposed system.

“…Current work in this area includes a system where users can reserve a slot on a highpriority highway lane by paying a premium [25], a vehicular ad-hoc networks (VANET) approach to traffic management in emergency and evacuation scenarios [26] traffic adaptive traffic lights for improved traffic co-ordination at intersections [27] and train -vehicle communications to manage their interactions at road and rail intersections [28]. These solutions micro manage distinct scenarios to provide some benefit but do not examine the effect on traffic in the entirety of the road network.…”

Traffic congestion is a very serious problem which is becoming ever worse as the growth in the number of cars on the road significantly out-paces the provision of road capacity. This paper presents a novel vehicle routing algorithm for TraffConan innovative Traffic Management System for wireless vehicular networks -and discusses its complexity. The algorithm combats the traffic congestion problem by seeking to optimize the usage of the existing road capacity, reduce vehicle trip times and decrease fuel consumption and the consequent gas emissions. Results demonstrate that the algorithm significantly increases road capacity utilisation and consequently reduces traffic congestion in comparison with an existing approach.
