Wireless Sensor Networks Powered by Ambient Energy Harvesting: An Empirical Characterization
Source: National University of Singapore
Wireless Sensor Networks Powered by Ambient Energy Harvesting (WSN-HEAP) can perform the task of continuous and remote monitoring of the environment without the need for replacement of batteries. The authors identify three important design considerations for wireless networking protocols in WSNHEAP: the unpredictable energy supply, the propagation losses in different environments and the suitable power level to use. In this paper, they perform an empirical characterization of commercially available solar and thermal energy harvesting sensor nodes. They deploy a transmitter-receiver pair at different distances and in various environments to conduct link measurements to determine the packet delivery ratio and RSSI values.
