Abstract
A wireless device network comprises: an unsynchronized wireless device in a time division multiple access based system; and a cognitive master in communication with the device, wherein the master processor is configured to: determine a number of time slots required for the master to transmit a message to and receive a response from the device, each time slot is a portion of a radio frequency spectrum over a frame period; when the number of time slots required are consecutively available, broadcast an announcement message indicating start of discovery of the unsynchronized device; wherein the device processor is configured to: generate a response message including a device ID; and broadcast the response message to the master; wherein the master processor is configured to: generate a correction factor based on at least one of a master transmit time and a master received time; and broadcast the correction factor to the device.
