Energy consumption is an important issue in the design of Wireless Sensor Networks (WSNs) which typically rely on portable energy sources like batteries for power. Recent advances in ambient energy harvesting technologies have made it possible for sensor nodes to be powered by ambient energy entirely without the use of batteries. However, since the energy harvesting process is stochastic, exact sleep-and-wakeup schedules cannot be determined in WSNs Powered solely using Ambient Energy Harvesters (WSN - HEAP). Therefore, many existing WSN routing protocols cannot be used in WSN - HEAP. In this paper, the authors design an opportunistic routing protocol (EHOR) for multi-hop WSN - HEAP.
