Abstract :
There is an increasing need to develop flexible, reconfigurable, and intelligent low power wireless sensor network (WSN) system for healthcare applications. Technical advancements in micro-sensors, MEMS devices, low power electronics, and radio frequency circuits have enabled the design and development of such highly integrated system. In this paper, we present our proposed wireless thermal sensor network system, which is separated into control and data paths. Both of these paths have their own transmission frequencies. The control path sends the power and function commands from computer to each sensor elements by 2.4 GHz RF circuits and the data path transmits measured data by 2.4 GHz in sensor layer and 60 GHz in higher layers. This hierarchy architecture would make reconflgurable mapping and pipeline applications on WSN possibly, and the average power consumption can be efficiently reduced about 60 % by using the adaptive technique.
