Vehicles have developed with an objective of safety, environment, and facility. In the current in-vehicle network, roughly four types of different networks are connected through gateways with the consideration of cost and efficiency by the property of control ECU, but the number of sensor node of this network frame is restricted. The number of sensor required by Advanced Safety Vehicle that provides more intelligent and automatic services, and the network frame in which the in-vehicle sensor data are maintained, managed, and manifested to provide the extensity of sensor. This paper propose a basic elements and functions of in-vehicle sensor network that can manage the in-vehicle sensors more efficiently, and a smart vehicle sensor network platform technique laying stress on gateway middleware software architecture based on AMI-C and OSGi standard to correspond with future ITS circumstances and automobile industry.

Open Standard Telematics Platform is based on the AMI-C architecture, which is a standard for efficiently integrating multimedia devices into a vehicle. VI(Vehicle Interface), which is defined on the AMI-C standard, performs a role of a gateway in an AMI-C network. This controls and provides vehicle information to the AMI-C compatible devices which are in the AMI-C network by converting vehicle information in the network domain into a logical structure. An integrated VI structure has been developed to provide a VS(Vehicle Service) on a standard platform. To minimize the message loss problem due to the platform operation delay which is caused by the power supply in the case of operating a CAN network of a vehicle, an interworking structure with a CAN gateway to provide an efficient VI has been implemented. The efficiency has been verified using CANoe which is a vehicle-network simulation tool.

Vehicles have been developed with the purpose of safety. A large number of sensors will be required in Advanced Safety Vehicle that provides more intelligent and automatic services in future ITS circumstances. Because current in-vehicle network must be changed to add new sensors, the numbers of sensors that can be added are restricted in current in-vehicle network. To manage the sensors more efficiently and to provide extensibility, we developed SCSN(Smart Car Sensor Network) which is an in-vehicle architecture and which includes gateway architecture based on AMI-C and OSGi standard. we have created SCSN testbed then deployed and optimized SCSN gateway. This paper introduces our research results about gateway architecture and features for SCSN to connect and handle effciently CAN sub-networks which are Power-train, Body comfort and extended Sensor Networks.

In the current vehicles, the number of sensor is increased, and the various in-vehicle networks exist together. So necessity of vehicle gateway for sensor network is appeared. In this paper, we propose the Sensor Network Gateway Platform. Proposed platform is based on AMI-C which is international standard for the least possible cost and development timeframe. And we propose the algorithm for sensor fail-safe. This algorithm estimate the lost sensing data to guarantee the vehicle service.
그리드 미들웨어 QoS 최적화를 위한 자원 모니터링 시스템
허용석(Yongsuk Hur),정재일(Jaeil Jung),임홍빈(Hongbin Yim) 한국정보과학회 2003 한국정보과학회 학술발표논문집 Vol.30 No.2Ⅲ
그리드 환경에서 효율적인 자원할당과 QoS를 보장하기 위해서는 먼저 각 자원의 사용가능한 정도를 정확히 파악하여야 한다. 본 논문은 정확한 자원을 측정하기 위한 리소스 모니터링 시스템을 제안하였다. 그리드에서의 모니터링 시스템은 기존의 모니터링 시스템과 차별화 되어있기 때문에 GGF(Global Grid Forum)에서 제안한 자원 측정 요구사항을 수용하여 구현하였다.
