A remote interactive consultation system based on wireless sensor networks is proposed for family health care works and non-hospital special case patient monitoring. The sensor nodes are integrated into a local area network to collect a variety of human physiological information, which is uploaded to Internet through the Code-Division Multiple Access (CDMA) wireless network technology and sent to the database based on GIS spatial location query technology for achieving electronic diagnosis. Users or administrators can visit remote monitor region through Internet. The results show that the system, using a star passive topology of static gateway and mobile detection node, combines intelligent-distributed wireless sensing, computing and wireless communication technologies. Hence the proposed system has a great practical value.
