COMMUNICATION METHOD AND APPARATUS IN WIRELESS BODY AREA NETWORK

摘要

Short range wireless communication is provided. A first node included in a Wireless Body Area Network (WBAN) communicates with at least one neighboring second node. The first node transmits or receives data to or from at least one device node connected to the first node during a Time Division Multiple Access (TDMA) period, using a super-frame in which the TDMA period, a TDMA schedule advertisement message (AD message) transmission period, and a Contention Access Period (CAP) are sequentially arranged. The first node broadcasts an AD message of the first node to the at least one second node during the AD message transmission period within the super-frame. Upon receiving an AD message from the second node during the CAP within the super-frame, the first node adjusts a data transmission or reception time for the at least one device node connected to the first node using the received AD message.
