Abstract

A node is configured for wireless communication with an access point according to a differentiated services control parameter. The node includes a controller configured to provide individualized control of the differentiated services control parameter setting corresponding to the node. The controller is further configured to receive data, assign a priority level to the data, and adjust the differentiated services control parameter setting for the node based on the priority level.

Claims

1. A node configured for wireless communication with an access point according to a differentiated services control parameter, the node comprising:

a controller configured to provide individualized control of the differentiated services control parameter setting corresponding to the node, the controller further configured to

receive data;

assign a priority level to the data;

adjust the differentiated services control parameter setting for the node based on the priority level;

perform a weighted sum calculation in order to assign the priority level to the data; and

determine a classification for the data, and to perform the weighted sum calculation based on the classification.

2. The node of claim 1 wherein the node is configured for wireless communication with the access point according to IEEE 802.11e protocol.

3. The node of claim 2, wherein the differentiated services control parameter is a Differentiated Services Code Point.

4. The node of claim 1, wherein the node is a patient monitoring device, and wherein the data is physiologic data acquired by the patient monitoring device.

5. A network comprising:

an access point; and

nodes configured for wireless communication with the access point according to a differentiated services control parameter;

wherein each of the nodes includes a controller configured to provide individualized control of the differentiated services control parameter setting corresponding to the node, the controller further configured to;

receive data;

assign a priority level to the data;

adjust the differentiated services control parameter setting for the node based on the priority level; and

determine a classification for the data, and to perform a weighted sum calculation based on the classification in order to assign the priority level to the data.

6. The network of claim 5, wherein the weighted sum calculation is one of a linear calculation, a non-linear calculation and a geometric calculation.

7. The network of claim 5 wherein the nodes are configured for wireless communication with the access point according to IEEE 802.11e protocol.

8. The network of claim 7, wherein the differentiated services control parameter is a Differentiated Services Code Point.

9. The network of claim 5, wherein one of the nodes is a patient monitoring device, and wherein the data is physiologic data acquired by the patient monitoring device.

10. The network of claim 9, wherein the physiologic data is one of alarm data, waveform data and vital sign data.

11. The network of claim 10, wherein the vital sign data is one of electrocardiogram data, blood pressure data, temperature data, blood gas measurement data, and airway gas measurement data.

12. The network of claim 11, wherein the access point is configured to transmit physiologic data received from the nodes to a central monitoring station, and wherein the central monitoring station is configured to display the physiologic data.

13. A method comprising:

receiving data, wherein the data is acquired by a node configured for wireless communication with an access point according to a differentiated services control parameter;

assigning a priority level to the data, wherein the priority level is assigned by a controller configured to provide individualized control of the differentiated services control parameter setting corresponding to the node;

adjusting the differentiated services control parameter setting for the node based on the priority level;

determining a classification for the data based by comparing the data to a threshold value; and

performing a weighted sum calculation based on the classification in order to assign the priority level to the data.

14. The method of claim 13, wherein the node is configured for wireless communication with the access point according to IEEE 802.11e protocol, and wherein adjusting the differentiated services control parameter includes adjusting a Differentiated Services Code Point.

15. The method of claim 13, wherein the node is a patient monitoring device, and wherein acquiring data includes acquiring physiologic data.
