With recent advances, the trend has shifted from battery-powered Wireless Sensor Networks towards ones powered by ambient energy harvesters (WSN-HEAP). In such networks, operability of the node is dependent on the harvesting rate which is usually stochastic in nature. Therefore, it is necessary to devise routing protocols with energy management capabilities that consider variations in the availability of the environmental energy. In this paper, the authors design OR-AHaD, an Opportunistic Routing algorithm with Adaptive Harvesting-aware Duty Cycling.
