Experiment of microwave power and data transmission scheduling for IEEE 802.11-based sensor networks

In wireless sensor networks, individual nodes must be batteryless to make them maintenance-free, which is particularly important for networks that have an enormous number of nodes. When these wireless batteryless nodes are microwave-powered devices, they would necessitate scheduling of power and data transmission. In addition, to ensure network sustainability, a constant amount of energy should be stored in the capacitors of the batteryless nodes. In the experiment conducted in this study, we confirm the necessity of scheduling. In addition, sleep periods are scheduled to ensure that a constant amount of energy remains in the capacitor.
