Based on the conventional physical parameters measurement of human body as an example, this paper has put forward a scheme of real-time health monitoring on wireless sensor networks. The scheme has been integrated into most detection sensors of human physiological parameters, And human physiological parameters for data acquisition, and the measured data is transmitted to the monitoring center through...
According to the present situation of the wireless communication technology in the mine underground, the article makes a compare and analysis of the present of widely use of IrDA, RFID, Bluetooth, UWB and ZigBee etc. Short distance wireless communication, and designs the mine underground personnel positioning system using RFID technology based on the research of transmission characteristics of radio...
A Time Division Duplex (TDD) approach is demonstrated for voice communication in the environment of wireless sensor networks. The architecture of the Voice Wireless Sensor Networks (VoWSN) is presented and the hardware designing of Voice Node and Gateway Node are described in detail. Voice quality of different scenarios such as indoor, corridor, corner and outdoor are tested. It is resulted that good...
