Abstract
Configuring and utilizing a body area network (BAN) is provided. In a configuration phase, configuration messages are sent for scheduling a plurality of backscatter devices such that during a data collection phase each of the plurality of backscatter devices is configured to transmit in an individually-assigned time slot. In the data collection phase, a data collector device receives, from the plurality of backscatter devices, sensor data messages including sensor data from the backscatter devices, the sensor data messages being scheduled according to the configuration phase.
Claims29
A method for configuring and utilizing a body area network (BAN), comprising:
- in a configuration phase, sending configuration messages for scheduling a plurality of backscatter devices such that during a data collection phase each of the plurality of backscatter devices is configured to backscatter from an excitation signal in an individually-assigned time slot;
- and
- in the data collection phase, receiving, to a data collector device from the plurality of backscatter devices, sensor data messages including sensor data from the backscatter devices, the sensor data messages being scheduled according to the configuration phase,
- wherein the configuration messages include a timestamp to synchronize system clocks of the plurality of backscatter devices.
