First Claim
1. A system, comprising:
- a hub having one or more processing units and RF circuitry for transmitting and receiving communications in a wireless network architecture; and
a plurality of sensor nodes each having a wireless device that includes circuitry with a transmitter and a receiver to enable bi-directional communications with the hub in the wireless network architecture,wherein the one or more processing units of the hub are configured to execute instructionsto determine a timing of at least one periodic guaranteed time slot for the plurality of sensor nodes,to determine a single timeslot definition signal that is defined with the timing of a first periodic guaranteed time slot for a first group of sensor nodes and a second periodic guaranteed time slot for a second group of sensor nodes of the plurality of sensor nodes,to transmit a first periodic beacon signal and the single timeslot definition signal to the plurality of sensor nodes,to transmit a second periodic beacon signal without the single timeslot definition signal to the plurality of sensor nodes, andto decode content of transmissions received from the second group of sensor nodes during the second periodic guaranteed time slot,wherein the single timeslot definition signal is separate from the periodic beacon signal,wherein at least one sensor node of the second group of sensor nodes is configured to detect a preamble of a transmission from one of the other sensor nodes of the second group of sensors nodes without decoding at least some of the content of the transmission during the second periodic guaranteed time slot to ascertain the transmission without needing to process data of the transmission.

Abstract
Systems and methods for providing communications within wireless sensor networks based on at least one periodic guaranteed time slot for sensor nodes are disclosed herein. In one embodiment, a system includes a hub having one or more processing units and RF circuitry for transmitting and receiving communications in a wireless network architecture. The system also includes a plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional communications with the hub in the wireless network architecture. The one or more processing units of the hub are configured to execute instructions to negotiate a timing of the at least one periodic guaranteed time slot for the plurality of sensor nodes once using a single timeslot definition signal.
