The recent major studies reveal that the transportation system of any country must focus on the road conditions for effective traffic management. The several parameters can be considered to identify the road conditions such as types of vehicles, speed limit on different roads, traffic and transport rules etc. The paper discusses about the two major and important concerns on the Indian roads scenario...
Increased traffic and hence congestion is a major problem in cities or urban areas. To mitigate this problem of congestion a real-time traffic density estimation model is essential. This research proposes one such model for estimating the traffic congestion level with the help of Vehicular Ad-hoc Network (VANET) and Cloud Computing. In this work, a novel architecture and algorithm has been proposed...
Vehicular Ad-hoc Network (VANET) cloud, a hybrid technology, provides several computational services to minimize traffic congestion, travelling time, accidents, and environmental pollution. In the proposed work, the concept of VANET cloud is used for helping the regulatory authorities in identifying the vehicles violating the traffic rules through sensors included as part of On Board Unit (OBU). When...
Security is one of the existing challenge in cloud enabled Vehicular Ad-hoc Network (VANET) communication. To address the security issues and to reduce payload overhead a novel method has been proposed for classification of VANET messages along with a Multi-hashed Binary Tree (MuBT) Algorithm. This algorithm verifies the identity and authenticity of the vehicles and messages exchanged. In addition...
Authentication is an essential framework for safe and secure communication of messages in VANETs. For authenticating messages the IEEE 1609.2 standard uses ECDSA as the standard digital signature algorithm. But the verification time for an ECDSA signature is very high. As a result an inside or an outside attacker could use a fraction of bandwidth and flood the network with invalid signatures resulting...
Applications in Vehicular Adhoc NETwork (VANET) require high security for end to end communication especially for sensitive information. It is necessary to restrict the unauthorized users from accessing the VANET services using a trusted infrastructure. In addition, messages exchanged should have minimum authentication delay and communication overhead. In this paper, a novel architecture is proposed...
Vehicular ad hoc networks (VANETs) involves vehicle to vehicle (V2V) and vehicle to infrastructure (V2I) communication and has received a greater attention in the recent years. Though safety is the primary motive for the development of vehicular ad-hoc network, they also facilitate applications like managing the traffic flow, monitoring the road conditions, dissemination of data and many more. Efficiency...
