사물인터넷은 각종 사물에 센서와 통신 기능을 가능한 매개체를 부착하여 실시간으로 데이터를 인터넷으로 주고받는 환경이나 기술을 의미한다. 인터넷으로 연결된 사물들이 데이터를 주고받아 스스로 분석하고 학습한 정보를 사용자에게 제공하거나 사용자가 이를 원격 조정할 수 있는 기술융합의 한 패러다임이다. 오늘날의 자동차 업계에서도 이를 적용하기위한 연구가 활발히 진행되고 있다. 이러한 네트워크 기술들이 융합 및 적용될 자동차를 커넥티드 카(Connected Car)라 하고, 커넥티드 카란 즉 인터넷과 모바일 기기, 그리고 나아가 운전자와 연결된 자동차를 의미 한다. 본 논문에서는 커넥티드 카의 개념과 주요 센서 기술 등을 설명하고 차후 발전 가능성이 높은 차량 네트워크 기술들에 대해 서술한다.

우리 주변에는 휴대폰, PDA단말기, 무선호출기, 인터넷 등 다양한 매체를 통한 정보 전달의 수단이 많이 있다. ITS(Intelligent Transport System : 지능형 교통시스템)는 기존의 도로교통 기반시설에 차량제어와 정보통신기술이 접목되어 교통의 효율성과 차량 운행의 안정성, 에너지 절약 등 많은 사회 편익 서비스를 제공하고 또한 국가적으로는 자원을 절약할 수 있는 기술이다. ITS는 기존의 교통 기반시설에 정보통신과 차량제어 등의 기반시설과 기술을 연계시켜 교통의 효율성과 차량운행의 안전성, 에너지 절약 등을 목표로 한다. 매우 다양한 기술과 기반시설이 활용되므로 ITS가 교통문화와 산업체에 미치는 파급효과는 매우 크다. 본 고에서는 ITS의 여러 가지 분야 중에서 정보통신 분야의 국내외 동향 및 TTA TC06의 향후 방향에 대하여 기술하고자 한다.

In the future, as autonomous vehicles become popular at home and abroad, the frequency of accidents involving autonomous vehicles is also expected to increase. In particular, when a fully autonomous vehicle is operated, various criminal/civil problems such as sexual violence, assault, and fraud between passengers may occur as well as the vehicle accident itself. In this case, forensics for accidents involving autonomous vehicles and accidents involving passengers in the vehicles are also about to change. This paper reviewed the types of security threats of autonomous vehicles, methods for maintaining the integrity of evidence data using blockchain technology, and research on digital forensics. Through this, it was possible to describe threats that would occur in autonomous vehicles using blockchain technology and forensic techniques for each type of accident in a scenario-type manner. Through this study, a block that helps forensics of self-driving vehicles before and after accidents by investigating forensic security technology of domestic and foreign websites to respond to vulnerabilities and attacks of autonomous vehicles, and research on block chain security of research institutes and information security companies. A chain method was proposed.

In recent years, image processing technology has played a critical role in the field of autonomous driving. Among them, image recognition technology is essential for the safety and performance of autonomous vehicles. Therefore, this paper aims to develop a hybrid image recognition system to enhance the safety and performance of autonomous vehicles. In this paper, various image recognition technologies are utilized to construct a system that recognizes and tracks objects in the vehicle's surroundings. Machine learning and deep learning algorithms are employed for this purpose, and objects are identified and classified in real-time through image processing and analysis. Furthermore, this study aims to fuse image processing technology with vehicle control systems to improve the safety and performance of autonomous vehicles. To achieve this, the identified object's information is transmitted to the vehicle control system to enable appropriate autonomous driving responses. The developed hybrid image recognition system in this paper is expected to significantly improve the safety and performance of autonomous vehicles. This is expected to accelerate the commercialization of autonomous vehicles.

We propose a traffic information service for which traffic data are collected over ad-hoc networks from neighbor vehicles, processed to minimize the data size, and eventually provided to its destination. The proposed scheme simply relies on the existing navigtion systems in vehicles and wireless communication devices for vehicle-to-vehicle communication, rather than on a separately established server. It allows collecting and analyzing traffic status of large areas without incorporating separated monitoring systems, e.g., probe cars and enables to provide accurate traffic information to drivers in timely manner. We also evaluate its performance by ns-3 simulation.

In this paper, we proposed scheme that obtain diversity gain in the cooperative communication to mitigate, applied to the effects of fading in the vehicle communication. Relay used bus that can available in the city environment. In addition, we applied the double rayleigh fading environment so that can applied in real-environments. Therefore, proposed scheme through this paper applied to vehicle communication, user can acquire a high quality service and the operation efficiency of the network is improved. Finally, performance of the proposed protocol is analyzed in terms of bit error rate.
