Abstract:
The present invention provides, on the basis of congestion of a network, an arrangement state of nodes, and a quality of a communication channel, a fast synchronization scheduling apparatus and method for reducing a listening time of a node that desires to join. The fast synchronization scheduling apparatus and method include a radio frequency (RF) transmission and reception module configured to transmit and receive RF signals from nearby channels, a received signal strength indicator (RSSI) reception and storage module configured to receive RSSI values from the RF signals received from the RF transmission and reception module and store the received RSSI values, a channel sorting module configured to measure Channel Quality Estimation (CQE) values of the respective channels by putting the RSSI values of the respective channels received from the RSSI reception and storage module into a CQE formula and to sort the channels in order of highest CQE value (highest channel quality) based on the measured CQE values, and a channel setting and advertisement packet (ADV) reception module configured to receive an input of a channel having the highest CQE value from the channel sorting module, set the channel, and start a listening operation to receive an ADV in the set channel.

Claim (Index 10):
A fast synchronization scheduling method for Time Slotted Channel Hopping (TSCH) in a congested industrial wireless network environment, the fast synchronization scheduling method comprising steps of:\n (a) measuring, by a received signal strength indicator (RSSI) reception and storage module, whether an RSSI value is found to exist in each of channels received from a radio frequency (RF) transmission and reception module  100 ; (b) detecting, by using the RF transmission and reception module again, an RSSI value from each of the channels when not even one RSSI value is found to exist among all the channels as a result of the measurement; (c) detecting RSSI values from two of all the channels when an RSSI value is found to exist in each of the channels as a result of the measurement; (d) measuring, by a channel sorting module, CQE values of the respective channels by putting the received RSSI values of the respective channels into a CQE formula, and sorting the channels in order of highest CQE value (a highest channel quality) based on the measured CQE values; (e) searching for other coordinators in a surrounding area using an advertisement packet (ADV) received from an ADV receiver, setting a number of the found coordinators and a good group, and delivering information about channels having high CQE values to a PAN coordinator; (f) generating, when a time slot for an ADV is allocated to each coordinator on the basis of the information delivered from the PAN coordinator and timeslot information is received by the coordinator, an ADV message and transmitting the generated ADV message in a designated channel during the time slot; and (g) selecting, when an ADV is not received by the time a predetermined number of slotframes have passed, a channel having the highest CQE value again on the basis of CQE values collected by that time, and returning to step (c) and proceeding with the subsequent steps.
