Abstract
A master device transmits beacon messages to a plurality of slave devices. The beacon messages specify upstream time slots, downstream time slots, and contention-based time slots. To register a respective slave device with the master device, the respective slave device transmits an association request to the master device during a contention-based time slot and receives an association response from the master device during a first downstream time slot. In response to receiving the association response, the respective slave device transmits an authentication request to the master device during an upstream time slot and receives an authentication response from the master device during a second downstream time slot.
