Energy Harvesting Network With Wireless Distributed Computing [PDF]
IEEE Systems Journal, 2019 Bulky processing tasks are expected to burden the limited resources of energy harvesters by draining the stored energy, and thereby, reaching rapidly to energy causality constraint. In such scenario, energy harvesters flip into sleep mode, and thereby, the execution time of the next task will be delayed until the energy harvesters revert back into ...

Harvesting Resource Allocation in Energy Harvesting Wireless Sensor Networks
CoRR, 2013 Considering an energy harvesting sensor network, the overall probability of event loss is derived. Based on this result, a variety of harvesting resource allocation schemes (sizing the energy storages and the harvesting devices, under a total cost constraint) are provided. Their performances are verified and compared through simulations.
