COMMUNICATION METHOD AND APPARATUS IN WIRELESS BODY AREA NETWORK

摘要

PURPOSE: A communication method in WBAN(Wireless Body Area Network) is provided to offer high channel utilization in high competitive environment. CONSTITUTION: If there is sensed result of collision, a processor(110) enters into the TDMA(Time Division Multiple Access) section. The processor transmits and receives data allocated time slot. If the TDMA section is completed, the processor broadcasts its own TDMA schedule announcement. The processor receives the TDMA schedule announcement from the other node during the access competition section. The processor renews the time table which stores the time information related to the time slot.
