Energy analysis in Zigbee based wireless sensor node powered by piezoelectric energy harvester

Recently, an integration of wireless sensor network with energy harvesters is getting more interested because it can extend the life time of battery in a sensor node, which is very important in many applications. This paper presents the concept of energy analysis in Zigbee based wireless sensor network, which is powered by a piezoelectric energy harvester to optimize the algorithms used in wireless sensor network. In this work, difference aspects related to piezoelectric energy harvester, characteristic of power consumption in Zigbee based wireless sensor node and concept of optimizing algorithms to balance input and output power in the integrated system are proposed. © (2014) Trans Tech Publications, Switzerland.
