CONSORTS-S: A mobile sensing platform for context-aware services

This paper proposes a mobile sensing platform that provides context-aware services for mobile users by accessing surrounding wireless sensor networks. The platform provides the following facilities: 1) communicating to wireless sensor networks via a mobile sensor router attached to a userpsilas mobile phone, 2) analyzing the sensed data derived from networks by cooperating with sensor middleware on a remote server to capture onepsilas contexts, and 3) providing context-aware services for mobile users of cellular telephones. The platform is designed to process the sensed data effectively through cooperation between a mobile phone, a mobile sensor router, and a sensor middleware on a remote server. In this paper, we describe the concept of a mobile sensing platform: CONSORTS-S and its architecture, and show a healthcare service as a prototype application of CONSORTS-S. The healthcare service is aware of userspsila conditions such as heartbeat, posture, and movement through monitors of physiological signals (e.g., electrocardiograph, thermometer, and 3-axis accelerometer) and environmental conditions (e.g. room temperatures) by communication with environmental sensors.
