Method for scheduling transmissions of global beacons in body area networks
First Claim
1. A method for scheduling transmissions of global beacons in a body area network (BAN), wherein the BAN includes master nodes, and the master nodes are arranged in a tree topology, the method comprising:
- propagating ascending global beacons (AGBs) from leaf nodes to a root node of the tree during an ascending period, wherein an AGB includes at least reservations of time slots during a time round;
processing AGBs by the root node to determine time slot occupancy information;
propagating descending global beacons (DGBs) from the root node to leaf nodes during a descending period, wherein a DGB includes at least reservations of time slots during the time round; and
processing DGBs by the master nodes other than the root node to update at least the slot occupancy information included in the DGBs.

Abstract
A method (400) for scheduling transmissions of global beacons in a body area network (BAN). The BAN includes master nodes and slave nodes where master nodes are arranged in a tree topology. The method comprises propagating ascending global beacons (AGBs) from leaf nodes to a root node of the tree during an ascending period (S420), wherein an AGB includes at least reservations of time slots during a time round; processing AGBs by the root node to determine time slot occupancy information (S430); propagating descending global beacons (DGBs) from the root node to leaf nodes during a descending period (S440), wherein a DGB includes at least reservations of time slots during the time round; and processing DGBs by master nodes other than the root node to update at least the slot occupancy information included in the DGBs (S450).

14. A non-transitory computer readable medium having stored thereon computer executable code, when executed, causing a processor to perform a process of scheduling transmissions of global beacons in a body area network (BAN), wherein the BAN includes master nodes, and the master nodes are arrange in a tree topology, the process comprising:
-
propagating ascending global beacons (AGBs) from leaf nodes to a root node of the tree during an ascending period, wherein an AGB includes at least reservations of time slots during a time round; processing AGBs by the root node to determine time slot occupancy information propagating descending global beacons (DGBs) from the root node to leaf nodes during a descending period, wherein a DGB includes at least reservations of time slots during the time round; and processing DGBs by the master nodes other than the root node to update at least the slot occupancy information included in the DGBs. - View Dependent Claims (15)
