Network middleware for flexible integration of sensor processing in home environment

This paper proposes a network middleware for sensor data integration in the environment where multiple sensors are distributed all over a room. The sensor data integration is realized by dynamic connections between the programs for sensor data collecting and processing on the middleware. The connections are based on a uniform program interface and search mechanism utilizing sensor service descriptors. The middleware enable to reduce dependency on sensors and home environment. It also enables to decide relations between the programs flexibly. Construction of a simple monitoring application for an occupant in our experimental environment sensing room confirms the feasibility of the network middleware.
