SYSTEM AND METHOD FOR COMMUNICATION IN A BODY AREA NETWORK SYSTEM
First Claim
1. A method for controlling data flow in a wireless body area network, the method comprising:
- transmitting sensor data from a plurality of sensor nodes to a gateway via a first transmission channel from a first set of transmission channels, using a multiplexing technique, wherein the sensor data comprises beacon packet loss information corresponding to the first transmission channel;
transmitting beacon data from the gateway to the plurality of sensor nodes via the first transmission channel from the first set of transmission channels, wherein the beacon data comprises sensor packet loss information corresponding to the first transmission channel;
determining channel packet loss information of the first transmission channel based on at least one of the beacon packet loss information and the sensor packet loss information;
comparing the channel packet loss information with a packet loss threshold; and
switching flow of the sensor data and the beacon data through a second transmission channel from a second set of transmission channels different from the first set of transmission channels, instead of the first transmission channel, if the channel packet loss information is greater than the packet loss threshold.

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.
