Abstract :
This paper presents the design and implementation of an autonomous system for monitoring and managing the energy consumption in smart home applications. The work introduces a low-power Ultra-Wideband (UWB) transceiver, fully integrated into a smart home sensor node with web-services software infrastructure. This unique combination enables novel applications characterized by extreme low energy while maintaining interoperability between heterogeneous wireless sensor networks (WSN). A prototype version of the UWB system is implemented with a custom-designed transmitter fabricated in UMC 130nm CMOS technology and a discrete receiver. The proposed fully integrated UWB transmitter consumes 39μW at the pulse rate of 1Mbps. The complete integrated sensor node including the sensor and its interface, microcontroller and UWB transmitter achieves an energy consumption of 5.31nJ/bit, which is one order of magnitude lower than commercial wireless technologies for smart home applications.
