Data Aggregation Scheduling in Battery-Free Wireless Sensor Networks

To break through the limitation of battery-powered wireless sensor networks, a novel kind of network, named battery-free wireless sensor network (BF-WSN), is proposed. Battery-free sensor nodes in BF-WSNs harvest energy from power sources in their ambient environment, such as solar power, wind power and radio frequency (RF) signal power, etc., instead of batteries. Therefore, the energy con...
