Abstract: A method for controlling data flow in a wireless body area network includes transmitting sensor data from a plurality of sensor nodes to a gateway via a first transmission channel. The method further includes transmitting beacon data from the gateway to the plurality of sensor nodes via the first transmission channel. The method also includes determining channel packet loss information of the first transmission channel based on at least one of a beacon packet loss information included in the sensor data and a sensor packet loss information included in the beacon data. The method further includes comparing the channel packet loss information with a packet loss threshold. The method also includes switching flow of the sensor data and the beacon data through a second transmission channel instead of the first transmission channel, if the channel packet loss information is greater than the packet loss threshold.

Abstract: The invention is focused toward enhancing a patient's mobility by providing seamless information/data transfer between medical monitoring devices such as a patient monitor, telemetry hubs, or another mobile monitoring system. The information or data, which are transferred among the medical devices include, but are not limited to, patient demographic information, wireless network, or pairing information. A set of wireless sensors (e.g. ECG, NIBP, Temp, SpO2), which are located on a patient's body, are connected wirelessly to a patient monitor, which is not a mobile device. When a clinician needs to move the patient from one location to a another location, the clinician brings the mobile monitor close to the fixed monitor to transfer the patient and wireless network information to the mobile monitor automatically. This enables the transfer of connected on-body wireless sensors from one medical device to another medical device without physically detaching them from a patient's body.
