Abstract:
This paper considers wireless link scheduling in a new setting: nodes with Energy Harvesting (EH) as well as energy sharing capabilities. We propose a Mixed Integer Linear Program (MILP) to determine 1) the shortest link schedule, whereby active links in the same slot adhere to the physical interference model; 2) the optimal transmission power of active links; and 3) the amount of energy shared by nodes in each slot. We also outline a novel heuristic algorithm to generate a link schedule for large-scale networks. In addition, we outline a distributed protocol that is used by nodes to independently determine whether to share energy and/or transmit data in each slot. Our results show that 1) energy sharing reduces schedule lengths by about 20% and 2) our distributed algorithm generates schedule lengths that are approximately 65% shorter as compared to a protocol that requires nodes to decide randomly whether to transmit data or/and share energy.
