Wireless energy harvesting sensor networks constitute a new paradigm, where\nthe motes deployed in the field are no longer constrained by the limited\nbattery resource, but are able to re-charge themselves through directed\nelectromagnetic energy transfer. The energy sources, which we call actors, are\nmobile and move along pre-decided patterns while radiating an appropriate level\nof energy, sufficient enough to charge the sensors at an acceptable rate. This\nis the first work that investigates the impact of energy transfer, especially\nconcerning the energy gain in the sensors, the energy spent by the actors, and\nthe overall lifetime in the resulting mobile sensor-actor networks. We propose\ntwo event-specific mobility models, where the events occur at the centers of a\nVoronoi tessellation, and the actors move along either (i)the edges of the\nVoronoi cells, or (ii) directly from one event center to another. We undertake\na comprehensive simulation based study using traces obtained from our\nexperimental energy harvesting circuits powering Mica2 motes. Our results\nreveal several non-intuitive outcomes, and provide guidelines on which mobility\nmodel may be adopted based on the distribution of the events and actors.\n
