Abstract
Configuring and utilizing a body area network (BAN) is provided. In a configuration phase, configuration messages are sent for scheduling a plurality of transmit-only devices such that during a data collection phase each of the plurality of transmit-only 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 transmit-only devices, sensor data messages including sensor data from the transmit-only devices, the sensor data messages being scheduled according to the configuration phase.
Claims20
A method for configuring and utilizing a body area network (BAN) including a plurality of transmit-only devices, each including a wakeup receiver, a transmitter, and an antenna switching circuit configured to switch between a transmit mode in which the transmitter is utilized to send sensor data messages and a receiving mode in which the wakeup receiver is configured to receive wakeup signals and default to when not transmitting, comprising:
- in a configuration phase, sending a wakeup signal including configuration information for scheduling the plurality of transmit-only devices such that during a data collection phase each of the plurality of transmit-only devices is configured to transmit in an individually-assigned time slot;
- and
- in the data collection phase, receiving, to a data collector device from the plurality of transmit-only devices, sensor data messages including sensor data from the transmit-only devices, the sensor data messages being scheduled according to the configuration phase.
A system for configuring and utilizing a body area network (BAN), comprising:
- a plurality of transmit-only devices, each including a wakeup receiver, a transmitter, and an antenna switching circuit configured to switch between a transmit mode in which the transmitter is utilized to send sensor data messages and a receiving mode in which the wakeup receiver is configured to receive wakeup signals and default to when not transmitting;
- and
- a data collector device, wherein
- in a configuration phase, the plurality of transmit-only devices are configured to receive, via the wakeup receiver, a wakeup signal including configuration information for scheduling transmissions of the plurality of transmit-only devices, such that during a data collection phase each of the plurality of transmit-only devices is configured to transmit in an individually-assigned time slot, and
- in the data collection phase, the data collector device is configured to receive, from the plurality of transmit-only devices, sensor data messages including sensor data from the transmit-only devices, the sensor data messages being scheduled according to the configuration phase.
