METHOD FOR DISTRIBUTING CONTENTION AMONG TERMINALS IN CONTENTION ACCESS PERIOD OF SUPERFRAME

摘要

Disclosed is a method for distributing contention among terminals in a Contention Access Period (CAP) of a superframe in regard to a Medium (or Media) Access Control (MAC) layer employing a beacon-enabled mode in IEEE 802.15.4 standard. The method includes: dividing the CAP or the superframe into a plurality of sub-periods, all having the same size; receiving an association request message from a relevant terminal; and allocating one of the plurality of sub-periods to the relevant terminal, and transferring information on the sub-periods to the relevant terminal through a beacon frame, by a Personal Area Network (PAN) coordinator.
