Lifetime maximization for sensor networks with wireless energy transfer

open access: yes2016 IEEE International Conference on Communications (ICC), 2016
In Wireless Sensor Networks (WSNs), to supply energy to the sensor nodes, wireless energy transfer (WET) is a promising technique. One of the most efficient procedures to transfer energy to the sensor nodes consists in using a sharp wireless energy beam from the base station to each node at a time. A natural fundamental question is what is the lifetime
