Simultaneous Lightwave Information and Power Transfer (SLIPT) for Indoor IoT Applications. (arXiv:1706.09624v1 [cs.IT])
来源于:arXiv
We present the concept of Simultaneous Lightwave Information and Power
Transfer (SLIPT) for indoor Internet-of-Things (IoT) applications.
Specifically, we propose novel and fundamental SLIPT strategies, which can be
implemented through Visible Light or Infrared communication systems, equipped
with a simple solar panel-based receiver. These strategies are performed at the
transmitter or at the receiver, or at both sides, named Adjusting transmission,
Adjusting reception and Coordinated adjustment of transmission and reception,
correspondingly. Furthermore, we deal with the fundamental trade-off between
harvested energy and quality-of-service (QoS), by maximizing the harvested
energy, while achieving the required user's QoS. To this end, two optimization
problems are formulated and optimally solved. Computer simulations validate the
optimum solutions and reveal that the proposed strategies considerably increase
the harvested energy, compared to SLIPT with fixed policies. 查看全文>>
