Low-Power Odor-Sensing Network Based on Wake-Up Nodes

Low-Power Odor-Sensing Network Based on Wake-Up Nodes

The localization of bad odors is a long standing issue with high relevance for affected people because of the health and safety implications. In order to enable the detection and localization of bad odors we propose a wireless, low-power consuming sensor network. The sensor nodes are designed to wake-up upon initial detection of a bad odor to then start to measure the strength of the odor. Taki...

An ultra low power wake-up signal decoder for wireless nodes activation in Internet of Things technology

  This paper proposes a new structure for digital address decoders based on flip-flops with application in wake-up signal generators of wireless networks nodes. Such nodes equipped with this device can be utilized in Internet of Things applications where the nodes are dependent on environment energy harvesting to survive for a long time. Different parts in these wireless nodes should have an e...

Ultra Low Power Wake-Up Receiver with Unique Node Addressing for Wireless Sensor Nodes

Effect of Hash Function on Performance of Low Power Wake up Receiver for Wireless Sensor Network

Next generation network will consist of different types of wireless networks like WSN, Wi-Fi, WiMAX, UMTS, LTE and etc. Wireless Sensor Network (WSN) finds unique and special application as compared to the said networks because sensors are deployed in a very secret, awkward and hostile environment like battle field etc. Various wireless sensor nodes are interconnected and form a Wireless Sensor...

Look up Table Based Low Power Analog Circuit Testing

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...
