Technology Brief:

Researchers at New Jersey Institute of Technology in the Department of Electrical and Computer Engineering have invented a low-complexity asynchronous wireless sensing and communication architecture for next generation low power wireless sensors, which reduces the power consumption by a large amount.

 

Wireless sensor networks employ spatially distributed autonomous sensors to monitor physical or environmental conditions. Today, wireless sensor networks have been widely used in many mobile and embedded systems. Wireless sensor networks are built of wireless sensor nodes. Each sensor node continuously senses an analog signal, converts the sensed signal into binary format digital data, and delivers the data wirelessly through radio transceivers to a processing device, such as a micro-controller. A limitation of such a wireless sensor is the high power consumption due to constant-interval sampling. Conventional synchronous sensor architectures with a constant sampling rate generate a large amount of null data and waste considerable energy when sensing a sparse signal. Moreover, current prevalent synchronous radio circuits only work with synchronous sensor front-end circuits. The invention seamlessly combines asynchronous sensing and asynchronous wireless communications and forms a complete asynchronous wireless sensing architecture that generates less data and is significantly more power efficient than synchronous sensor architectures.
