Opportunistic Routing in Large - scale Energy Harvesting Wireless Sensor Networks by Hossein

Opportunistic Routing in Large-scale Energy Harvesting Wireless Sensor Networks Hossein Shafieirad Master of Applied Sciences Graduate Department of Electrical and Computer Engingeering University of Toronto 2016 Energy self-sufficiency is one of the main bottlenecks in the implementation of wireless sensor networks (WSNs). In this regard, energy harvesting (EH), the capture of energy from ambient sources of renewable energies, is a promising solution to the energy problem. However, the resulting randomness in the energy available to nodes forces the redesign of the communications protocols. Of specific interest here is to enable the delivery of sensed data to a fusion center in the EH-WSN. In this thesis, we consider two open problems of practical importance to the implementation of large-scale WSNs. First, we propose the notion of energy outage rate for a single link in WSN as a tool for online consideration of EH in such networks. Second, we propose and mathematically analyze an energyaware, opportunistic routing protocol for large-scale multi-hop EH-WSNs. Our routing protocol significantly increases the rate of data delivery as compared to the state-of-theart technologies.
