Abstract:
1. A method of providing a carrier sense multiple access (CSMA) time slot in a hierarchical communication network, comprising: generating at least one beacon frame within a beacon period, wherein the at least one beacon frame carries information on a CSMA time slot and an attribute information used to identify an applicable device of the CSMA time slot; and sending the beacon frame to one or more intermediary network devices that parse, re-encapsulate, and broadcast the re-encapsulated beacon frame within the beacon period, and providing the CSMA time slot for the applicable device, so that the applicable device sends a packet by using the CSMA time slot, wherein the at least one beacon frame carries information on at least two CSMA time slots and attribute information separately used to identify an applicable device of each CSMA time slot.
