As the demand for ubiquitous mobile wireless Internet grows, vehicles are receiving a lot of attention as new networking platforms. The demand for 4G all-IP networks encourages vehicle networks to be connected using IPv6. By means of network mobility (NEMO) support, we can connect sensors, controllers, local ,servers as well as passengers' devices of a vehicle to the Internet through a mobile router. The mobile router provides the connectivity to the Internet and mobility transparency for the rest of the mobile nodes of an in-vehicle nv6 network. So, it is .important for the mobile router to assure reliable connection and a sufficient data rate for the group of nodes behind it. To provide reliability, this paper proposes an adaptive multihoming architecture of multiple mobile routers. Proposed architecture makes use of different mobility characteristics of different vehicles. Simulation results with different configurations show that the proposed architecture increases session preservation thus increases reliability and reduces packet loss. We also show that the proposed architecture is adaptive to heterogeneous access environment which provide different access coverage areas and data rates. The result shows that our architecture achieves sufficient data rates as well as session preservation.

본 논문에서는 자율-구성 차량 네트워크 환경에서 차량 내 정의된 서비스를 정의하기 위한 새로운 주소 체계를 제안한다. 기존 IPv6 기반 주소 설정 기법은 차량 내에 서비스를 정의할 수 있는 필드가 존재하지 않는다. 따라서 자율-구성 차량 네트워크 구축 시 기존 방법에 한계점이 있다. 따라서 본 논문에서는 NAT 개념을 적용하여 만들어진 IPv6 기반의 ULA 주소 체계를 활용하여 차량 내 서비스를 식별할 수 있는 주소 체계를 제안한다.
