SERVICE PROCESSING METHOD AND SYSTEM FOR WIRELESS BODY AREA NETWORK

摘要

Disclosed are a service processing method and system for a wireless body area network (WBAN). Binary tree networking is performed on all sensor nodes and a central management node, and the central management node is the top of a network. The method comprises: performing timeslot allocation of sensor nodes according to network distribution; when an emergency service occurs, a sensor node where the emergency service occurs broadcasting a waking signal and triggering all the sensor nodes to enter an emergency communication state, and a sensor node at a normal communication state giving up a current timeslot; and the sensor node with the emergency service and a parent node of an upper layer to which the sensor node directly belongs performing emergency service processing by sequentially occupying timeslots from a current timeslot to a timeslot of completing the service according to a low-to-high order from a network layer. In the embodiments of the present invention, timeslot allocation is performed on WBAN nodes according to binary tree network distribution, and all the nodes are triggered to enter an emergency communication state by means of a waking signal; and the sensor node on which the emergency service occurs and a parent node of an upper layer to which the sensor node directly belongs perform emergency service processing by occupying timeslots from a current timeslot to a timeslot of completing the service.
