NODE SCHEDULING AND ADDRESS ASSIGNMENT WITHIN AN AD-HOC COMMUNICATION SYSTEM
First Claim
1. A method for a Personal Area Network Coordinator (PANC) to assign addresses within an ad-hoc communication system, the method comprises the steps of:
- determining a number of nodes in communication with the PANC;
dividing a superframe into a number of slots corresponding to the number of nodes in communication with the PANC or a maximal number of allowed slots, whichever is smaller; and
assigning each of the nodes in communication with the PANC a slot to utilize for communication with the PANC.

Abstract
A method and apparatus for address assignment and node scheduling within an ad-hoc communication system is provided herein. During operation a personal area network coordinator (PANC) (40) will divide a superframe (301) into a plurality of slots, assigning each sub-tree under the PANC'"'"'s direct child node to each slot for communication with the PANC. Each sub-tree coordinator will be assigned a same logical address by the PANC. As a result, a sub-tree coordinator synchronizes to the PANC node in only one subsuperframe slot assigned by the PANC with different sub-tree coordinators synchronizing to the PANC in different slots.
