title: Integration of RFID and web service for assisted living.
abstract: The number of people over 65 years old throughout most stable and prosperous countries in the world is increasing. Availability of their care in their own homes is imperative because of the economic reasons and their choices where to live (World Health Organization, Definition of an older or elderly person. http://www.who.int/healthinfo/survey/ageingdefnolder/en/ ; EQUIP-European Framework for Qualifications in Home Care Services for Older People, http://www.equip-project.com ; Salonen, 2009). "Recent advancement in wireless communications and electronics has enabled the development of low-cost sensor networks. The sensor networks can be utilized in various application areas." (Akyildiz, et al. 2002) These two statements show that there is a great promise in wireless technology and utilizing it in assisted living might be very beneficial to the elderly people. In this paper, we propose software architecture called Location Windows Service (LWS) which integrates the Radio Frequency Identification (RFID) technology and the web service to build an assisted living system for elderly people at home. This architecture monitors the location of elderly people without interfering in their daily activities. Location information messages that are generated as the elderly move from room to room indicate that the elderly person is fit and healthy and going about their normal life. The communication must be timely enough to follow elderly people as they move from room to room without missing a location. Unacknowledged publishing, subscription filtering and short location change messages are also included in this software model to reduce the network traffic in large homes. We propose some defense schemes being applied to the network environment of the assisted living system to prevent any external attacks.
