Transmission Power Control in 2-D Wireless Sensor Networks Powered by Ambient Energy Harvesting

The authors are witnessing pervasive use of Wireless Sensor Networks (WSN)s in a wide variety of applications such as monitoring of road infrastructure. As they are expected to be deployed in harsh environments for long durations, the research community have turned their attention to tapping on ambient energy to power such networks. However, since energy harvesting rates are still significantly lower than the power consumption in each wireless sensor node, the energy availability is sporadic, making the design of runtime policies in WSN powered by ambient energy harvesting (WSN-HEAP) to maximize performance an important but challenging task.
