The present invention relates to a method and system for controlling contention period channel access, and in particular, to a system and method for controlling priority-based contention period channel access for reducing complexity in a WBAN MAC protocol which grants levels according to the importance of data and preferentially transmits data in a next beacon period having higher levels than data, the transmission of which was delayed in a previous beacon period. The present invention is supported by: a national research and development project, unique number 2011-0015744, with a research period of Jun. 1, 2011 to May 31, 2014; a WBAN core algorithm research project for an efficient smart medical space as a basic research project/staff researcher support project/core research support project supervised by the Ministry of Education, Science and Technology, unique project number NIPA-2011-(C1090-1121-0003), with a research period of Nov. 1, 2006 to Dec. 31, 2014; and an oriental and western new medical u-Life Care technology research project for a university IT research center promotion and support project supervised by the Ministry of Knowledge and Economy.
A system for controlling channel access in a priority-based contention period to reduce complexity in a WBAN MAC protocol performing contention-based communication using beacons, wherein the system comprises a coordinator that classifies packets received from communication devices according to priority levels, identifies the delay of packets transmitted in the previous beacon period, and grants transmission priority for the next beacon period to a device having a priority higher than or equal to that of a delayed packet.
A method for controlling channel access in a priority-based contention period to reduce complexity in a WBAN MAC protocol, the method comprising:
