A network-centric approach to sensor-data and service integration

Sensor net require the information integration of various sensors and related contents and services. The present paper describes an approach to the construction of a sensor network using a content-aware network so called messaging network. A messaging network can be constructed as a structured overlay network. The proposed scheme enables loosely-coupled integration of sensor data and related services. The proposed scheme can be realized by an overlay network over an ordinary IP network. The paper also introduces a policy mediation, which is a kind of message mediation, for over-lay networks having each own policies enables secure overlay networks inter-operation. This paper also introduces a secure data-store grids for sensor network. The data-store grids helps to construct and manage as secure, flexible, elastic, and sustainable loosely coupled integration of sensor data and related services. The application of the proposed scheme to SmartGrid and health-care system are be discussed.
