Energy-Efficient Network Protocols for Domestic IoT Application Design

The gathering of data from household IoT-enabled devices will incur an energy cost and, in this paper, we investigate the impact of different communications technologies and protocols on that cost. As a first step towards energy-efficient design, we have measured the power consumption of several popular wireless interfaces – Bluetooth (Classic and Low Energy), ZigBee, Wi-Fi and 433 MHz module (RF433). We then combine these measurements through the example of a simple domestic stock control...
