A METHOD FOR SCHEDULING TRANSMISSIONS OF GLOBAL BEACONS IN BODY AREA NETWORKS

摘要

The present invention relates to a method 400 for scheduling transmissions of global beacons in the body area network (BAN). BAN includes master nodes and the slave nodes to be the master nodes are arranged in a tree topology. Method comprises the steps of passing the rising global beacons (AGBs) to the root node from the leaf node of the tree during the rising period, AGB, the transmission phase the rising global beacons (AGB) that includes the reservation time slot for at least a time round (S420 ); Processing the AGB by the root node to determine time slot occupancy information (S430); The method comprising passing the descending global beacons (DGBs) from the root node to leaf nodes during a falling period, the DGB is descending global beacon transmission step, including the reservation of time slots during at least a time round (S440); And at least a step (S450) of processing the DGB by the master node that is not the root node to update the slot occupancy information included in the DGB. ;
