Abstract
Query based duplex vital signal monitoring system using wireless sensor network for Ubiquitous Healthcare was designed and tested. In this system, a wireless sensor network node attached on the human body provides sensor signal of an ECG (Electrocardiogram) and body temperature from multiple patients using wireless sensor network technology. A mote-based 3-lead ECG and body temperature monitoring system operating in wireless sensor network nodes was developed. The signal from sensors first is amplified with low noise instrument amplifier, and output of which is then fed to data acquisition board for connectivity to the sensor node. Vital signal from multiple patients can be relayed using an adaptive, multi-hop routing scheme to a wired base-station. The sampled signal will be filled in the form of packets for transmission using Zigbee compatible IEEE 802.15.4 standard wireless communication. The patients will be identified by the unique id assigned to the each mote. Among various existing routing protocols, presently simple variant of DSDV algorithm with a single destination node (the base-station) has being used for routing and transmission. Each mote in network simultaneously acts as transmitter, receiver and a router.
