An Orientation-Independent Multi-Input Energy Harvesting Wireless Sensor Node

Deploying energy harvesting-based wireless sensor nodes (WSNs) in challenging environments often means we do not have precise control over the placement and orientation of nodes. This article introduces a novel smart WSN whose operation does depend on its orientation. The proposed unit is cube-shaped device, each side which complete module, sharing common storage communication bus with other faces. In this article, an energy-efficient algorithm designed based concepts “strongest face” radio face.” facilitates information among faces cube goal harvesting maximum possible from all sides, aggregating shared bus, then, using strongest face to transmit sensed signal base station. concept verified 50-cm 3 laboratory prototype built off-the-shelf components. experimental results show that device successfully transmits data even worst case where only one face, may be transmitting energy.
