The IEEE Audio Video Bridging (AVB) technology is nowadays under consideration in several automation domains, such as, automotive, avionics, and industrial communications. AVB offers several benefits, such as open specifications, the existence of multiple providers of electronic components, and the real-time support, as AVB provides bounded latency to real-time traffic classes. In addition to the above mentioned properties, in the automotive domain, comparing with the existing in-vehicle networks, AVB offers significant advantages in terms of high bandwidth, significant reduction of cabling costs, thickness and weight, while meeting the challenging EMC/EMI requirements. Recently, an improvement of the AVB protocol, called the AVB ST, was proposed in the literature, which allows for supporting scheduled traffic, i.e., a class of time-sensitive traffic that requires time-driven transmission and low latency. In this paper, we present a schedulability analysis for the real-time traffic crossing through the AVB ST network. In addition, we formally prove that, if the bandwidth in the network is allocated according to the AVB standard, the schedulability test based on response time analysis will fail for most cases even if, in reality, these cases are schedulable. In order to provide guarantees based on analysis test a bandwidth over-reservation is required. In this paper, we propose a solution to obtain a minimized bandwidth over-reservation. To the best of our knowledge, this is the first attempt to formally spot the limitation and to propose a solution for overcoming it. The proposed analysis is applied to both the AVB standard and the AVB ST. The analysis results are compared with the results of several simulative assessments, obtained using OMNeT++, on both automotive and industrial case studies. Real-Time Syst (2017) 53:526-577 527 between the results of the analysis and the simulation ones shows the effectiveness of the analysis proposed in this work.

“…It is noted that the cycle time of in-vehicle traffic can be varied from 10 ms up to 500 ms depending on the applications [14]. The traffic pattern of HPGP of all priority levels can be well suited within the allowed service rate of control traffic class [15].…”

“…Assuming that all priority flows are with the highest frequency of transmission F 1 = F 2 = F 3 = F 4 = C BP , we can obtain the worst delay performance of HPGP as 2.1 ms which can satisfy delay requirement of major control and safety application classes defined by CAN and LIN buses [14], [15], e.g., 10 ms.…”

Abstract-The increasing complexity of automotive electronics has put considerable pressure on automotive communication networking to accommodate in-vehicle information flows. The use of power lines has been a promising alternative to in-vehicle communications because of elimination of extra data cables. In this paper, we focus on the latest HomePlug Green PHY (HPGP) which has been promoted by major automotive manufacturers for green communications with electric vehicles, and study its worst-case access delay performance in supporting delaycritical in-vehicle applications using both theoretical analysis and the simulation. Specifically, we apply Network Calculus as a deterministic modeling approach to evaluate the worst delay and further verify its performance using the OMNeT++ simulation. Evaluation results are also supplemented to compare with legacy methods and provide useful guidelines for developing HPGP based vehicular power line communication systems.

Many automobile drivers have come to believe that installation of video recording equipment in a car is essential to providing evidence in case of a car accident and to facilitate reporting to police. Thus, it is important to develop an in-vehicle video recorder with high resolution to document accidents. To provide such video quality, the H.264 video format, which offers high compression and good quality, has been used for an in-vehicle video recorder. However, due to problems with fabricated evidence of digital records, we propose a new watermark method to authenticate in-vehicle video. This watermarking scheme authenticates and protects in-vehicle video. The proposed scheme manipulates the quantization table of the I-frames in car surveillance videos and embeds watermarks in the I-frames. Experimental verification was done to confirm the authentication and tamper detection of the proposed watermark image method for in-vehicle video.
