Recent advances in the development of ultra-low-power transceivers and energy harvesting devices (e.g., solar cells) enable self-sustainable and perpetual wireless networks. In contrast to legacy wireless sensor networks, where the available energy only decreases as the nodes sense and forward data, in energy harvesting networks the available energy also increases via a replenishment process. Energy replenishment results in a significantly novel model, which poses new challenges in the design of resource allocation and routing algorithms.
EnHANTs – Energy Harvesting Networked Tag Networks are networks with nodes harvesting energy from solar or movement cells, first developed by researchers at Columbia University. In this work we introduce HDR – Hysteresis Driven Routing, the first algorithm for routing messages in such networks. After first introducing the basic paradigm using a simple topology, we apply the algorithm to larger networks, new configurations and a variety of traffic patterns. We also develop a model for determining optimal performance and show by simulation that HDR performs close to optimal for a large variety of parameters.
Adrian Segall received the B.Sc. and M.Sc. degrees in Electrical Engineering from the Technion, Israel Institute of Technology in 1965 and 1971, respectively, and the Ph.D. degree in Electrical Engineering with a Minor in Statistics from Stanford University in 1973. He is presently Benjamin Professor of Computer-Communication Networks in the Department of Electrical Engineering, Technion, Israel Institute of Technology. He held faculty and visiting positions with MIT, IBM, AT&T and Lucent Bell Labs. His current research interests are in the area of wireless, sensor and Ad-Hoc Networks.
