Our objective is to crowdsource wireless energy from IoT devices to create a green IoT environment. Energy could be harvested using renewable energy sources, i.e., the kinetic movement of IoT users or their body heat. For example, a smart shoe may harvest energy from the physical activity of its user. The harvested energy could be used to charge the nearby IoT devices wirelessly. This research project aims to propose a service model for crowdsourced energy. The project also aims to propose a novel framework to compose crowdsourced energy services in a dynamic IoT environment.
