The development of medical sensor networks (MSNs) is imperative for e-healthcare, but security remains a formidable challenge yet to be resolved. Traditional cryptographic mechanisms do not suffice given the unique characteristics of MSNs, and the fact that MSNs are susceptible to a variety of node misbehaviors. In such situations, the security and performance of MSNs depend on the cooperative and...
Off-the-shelf wireless sensing devices open a wide range of perspectives for tetherless biomedical monitoring. Yet most applications considered to date imply either indoor real-time data streaming or ambulatory data recording. Disruption-tolerant networking is a means to cope with challenging situations where continuous end-to-end connectivity between communicating devices cannot be guaranteed. In...
By adding a wireless sensor network into a health monitoring system, I have found a method by using the combination of ZigBee and wireless LAN architecture to realize a remote medical monitoring system. The system's nodes and base stations use the short range communication standard: 802.15.4 / ZigBee standard. This system can collect various information from patients, achieving the remote medical...
A system to remotely monitor a patientpsilas oxygen saturation (%SpO2) levels is described. The data was continuously measured using a pulse oximeter and then transferred to a central monitoring station via a wireless sensor network for storage and display. Crossbow MICAz motes were programmed to serve as the network nodes. One mote was interfaced to the pulse oximeter for data acquisition and the...
