USN 서비스를 위한 센서 네트워크 이동성 지원 기술 연구

Abstract

USN(Ubiquitous Sensor Network) services over the Internet are gaining increased acceptance due to the generation of the application services in a wide range of civilian and military fields, including ensuring safety and security, environment and habitat monitoring and real-time healthcare. These services are based on IP(Internet Protocol) and the intelligent sensor nodes that could be deployed "anywhere, anytime, by anyone and anything". One of the critical issues in USN services is the mobility supporting function that is embossed as very important and plays a key role in deploying IP-based USN application services. In this thesis, we propose two mobility supporting technologies. First, the node-based mobility supporting technology is envisaged. This is based on LR-WPAN and IPv4, and it is simulated on NS-2 simulator. Second, the network-based mobility supporting technology is suggested conceptually. The proposed concept is based on 6LowPAN and IPv6. These research efforts are expected to improve the mobility supporting technology in achieving convergence among USN services and IP-based networking, and research results will help expedite the deployment of USN services.
