Abstract
A method for communicating data in a wireless control area network, where the wireless control area network includes one or more sensor nodes configured to facilitate acquisition of patient data and an access coordinator configured to facilitate acquisition of the patient data from the one or more sensor nodes, is presented. The method includes creating a correlation between one or more poll packets from an access coordinator and time of arrival of data at one or more sensor nodes. Systems and computer-readable medium that afford functionality of the type defined by this method is also contemplated in conjunction with the present technique.

13. A system for communicating data in a wireless control area network, the system comprising:
-
one or more sensor nodes configured to facilitate acquisition of data;
wherein the one or more sensor nodes comprise a processing module, and wherein the processing module is configured to;prepare data for transmission from the one or more sensor nodes to an access coordinator in response to a first beacon transmitted from an access coordinator to the one or more sensor nodes, wherein the first beacon is configured to indicate a start of a new communication cycle; generate a first data frame, wherein the first data frame is indicative of a sensor node having data to transmit, and wherein the first data frame is configured to create a correlation between a poll packet arrival time and a data arrival time at the one or more sensor nodes; transmit the first data frame from at least one sensor node to an access coordinator; communicate data from the one or more sensor nodes to an access coordinator in response to the second beacon; an access coordinator configured to facilitate acquisition of data from the one or more sensor nodes, wherein the access coordinator comprises a processing module, and wherein the processing module is configured to; transmit a first beacon to the one or more sensor nodes, wherein the first beacon is configured indicate a start of a new control cycle; transmit a second beacon from the access coordinator to a sensor node transmitting the first data frame, wherein the second beacon is configured to; initiate a polling cycle; and acknowledge receipt of the first data frame. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
