Lane Monitoring System for Driver Assistance Using Vehicle to Infrastructure Connection

01 Jan 2021-pp 51-63
TL;DR: In this article, a concept called lane monitoring system uses passive infrastructure along roadway and attempts to evolve them to fulfil the needs of evolving mobility solutions, which can be used in VANETs.
Abstract: Vehicular ad hoc networks have gained importance since their advent in 1998 and the technology has been having an exponential growth in contribution towards its betterment and stability. VANET allows local communication between vehicles and infrastructure along the road. Every vehicle shares critical information with every other vehicle in its vicinity for ensuring passenger safety and also allows access to Internet for multimedia entertainment. With all such applications and features, VANET has its own share of insecurities and limitations. Many successful attempts have been made in the last decade to solve the identified problems, but with rapid advancements in technology, the complexity of security solutions and network architectures increase despite having a solution for all kinds of problems. Therefore, it is necessary to simplify the existing VANET and begin working on alternate concepts that use existing technologies and protocols. A concept called lane monitoring system uses passive infrastructure along roadway and attempts to evolve them to fulfil the needs of evolving mobility solutions.

TL;DR: This report focuses on two limitations: real-time communication constraints and unfairness dedication of channel with using distributed coordination function on Medium Access Control (MAC) layer.
Abstract: This report is to present the research of Wireless Access for Vehicular Environments (WAVE). It introduces the basic technologies used in this standard, also proposes some limitations and applications of this criteria. Based on this, this report focuses on two limitations: real-time communication constraints and unfairness dedication of channel with using distributed coordination function on Medium Access Control (MAC) layer. Some ideas for improving these limitations are raised with the results of simulations. For the real-time problem, a Time Division Multiple Access (TDMA) MAC layer is studied and evaluated. For the unfairness dedication of channel problem, a priority is given to each node of different speed to achieve a dynamic contention window size. The result of simulation shows this method efficiently improves this limitation. Keywords— IEEE 802.11p, IEEE P1609, WAVE, MAC, RSU,

TL;DR: A fully distributed and localized algorithm called D-FPAV (distributed fair power adjustment for vehicular networks) for adaptive transmit power adjustment which is formally proven to achieve max-min fairness is proposed.
Abstract: Improving the safety of drivers and passengers by wirelessly exchanging information between vehicles represents a major driving force for the design of vehicular ad hoc networks. In a heavy loaded 802.11-based network, however, safety-related packets might collide frequently and cannot be decoded by a receiver, thus they might not be effective in increasing the safety level on the roads. In this paper, we propose to use transmit power control in order to reduce packet collisions, while taking into account the major design goal of vehicular ad hoc networks, i.e. increasing safety. While previous work has addressed the issue of power control primarily for optimizing network capacity and/or connectivity, the optimization criterion for improving safety has to be built upon the concept of fairness: a higher transmit power of a sender should not be selected at the expense of preventing other vehicles to send/receive their required amount of safety information. In this paper, we propose a fully distributed and localized algorithm called D-FPAV (distributed fair power adjustment for vehicular networks) for adaptive transmit power adjustment which is formally proven to achieve max-min fairness. Furthermore, we investigate the effectiveness and robustness of D-FPAV through extensive simulations based on a realistic highway scenario and different radio propagation models

TL;DR: An overview on current research state, challenges, potentials of VANETs as well the way forward to achieving the long awaited ITS is provided.
Abstract: Recent advances in wireless communication technologies and auto-mobile industry have triggered a significant research interest in the field of VANETs over the past few years. VANET consists of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications supported by wireless access technologies such as IEEE 802.11p. This innovation in wireless communication has been envisaged to improve road safety and motor traffic efficiency in near future through the development of Intelligent Transport Systems (ITS). Hence, government, auto-mobile industries and academia are heavily partnering through several ongoing research projects to establish standards for VANETs. The typical set of VANET application areas, such as vehicle collision warning and traffic information dissemination have made VANET an interested field of wireless communication. This paper provides an overview on current research state, challenges, potentials of VANETs as well the way forward to achieving the long awaited ITS.

Abstract: Vehicular Ad hoc Networks (VANETs) are the promising approach to provide safety and other applications to the drivers as well as passengers. It becomes a key component of the intelligent transport system. A lot of works have been done towards it but security in VANET got less attention. In this article, we have discussed about the VANET and its technical and security challenges. We have also discussed some major attacks and solutions that can be implemented against these attacks. We have compared the solution using different parameters. Lastly we have discussed the mechanisms that are used in the solutions.
