Abstract: An acquisition method for data in a wireless body area network and a central device, the acquisition method includes: a central device acquiring topology structure information of a network formed by node devices, and according to the topology structure information of the network determining time slot information about a super-frame; after time slot information is published, acquiring service data packets of an Exclusive Access Phase EAP, a Random Access Phase called RAP and a managed access MAP1 phase in sequence; acquiring packet loss information in the MAP1 phase, and allocating time slots of a managed access MAP2 phase according to the packet loss information; and after the allocated time slots are published, acquiring service data packets in the MAP2 phase according to the allocated time slots. The technical solution can realize the reliable transmission of data in a wireless body area network and reduce the power consumption and time delay.

Abstract: Provided are information interaction methods, devices and system for a Wireless Body Area Network (WBAN). The method includes that: a Hub sends beacon frames to nodes according to a preset superframe structure and receives, according to a preset superframe structure, information sent by the nodes. The preset superframe structure includes three phases. The first phase includes a first beacon period, a first timeslot period and a second timeslot period, the first timeslot period being used by nodes to send an emergency service and the second timeslot period being used by nodes to send an ordinary service. The second phase includes a second beacon period and a third timeslot period, the third timeslot period being used by nodes to complementarily send a service. The third phase includes a fourth timeslot period, the fourth timeslot period being used by nodes to send a sleep application and/or an access application.
