Abstract
Systems and methods are disclosed for providing scheduled communication between a primary network, such as a time synchronized channel hopping (“TSCH”) network, and a secondary network, such as a carrier sense multiple access (“CSMA”) network. During a first selected slot-offset in a TSCH hopping pattern, a gateway node communicates with a primary network node. During a second selected slot-offset in the TSCH hopping pattern, the gateway node communicates with a secondary network node. A communication schedule identifies the source and destination nodes and channel frequency for each slot-offset. The communication schedule is set such that the CSMA wake-up period for the secondary network is synchronized with the second slot-offset in the TSCH hopping pattern.
Claims20
A gateway node, comprising:
- a transceiver device configured to communicate with a plurality of primary network nodes and with a secondary network node, wherein the plurality of primary network nodes communicate on multiple channels using a time synchronized channel hopping networking protocol and wherein the secondary network node communicates on a single channel using a carrier sense multiple access networking protocol by communicating during wake-up intervals;
- a processor communicatively coupled to the transceiver device;
- and
- a non-transitory computer-readable medium in which instructions executable by the processing device are stored, the instructions for causing the processing device to perform operations comprising:
- communicating a first message with a primary network node during a first selected slot-offset of a plurality of slot-offsets of the time synchronized channel hopping networking protocol, wherein the primary network node is among the plurality of primary network nodes;
- and
- communicating a second message with the secondary network node during a second selected slot-offset of the plurality of slot-offsets of the time synchronized channel hopping protocol, wherein the wake-up intervals of the secondary network node are synchronized with the second selected slot-offset.
A method, comprising:
- communicating a first message with a primary network node during a first selected slot-offset of a plurality of slot-offsets of a time synchronized channel hopping networking protocol, wherein the primary network node is among the plurality of primary network nodes that communicate on multiple channels using the time synchronized channel hopping protocol;
- and
- communicating a second message with a secondary network node during a second selected slot-offset of the plurality of slot-offsets of the time synchronized channel hopping protocol, wherein wake-up intervals of the secondary network node are synchronized with the second slot-offset, and wherein the secondary network node communicates on a single channel using a carrier sense multiple access networking protocol.
A method, comprising:
- during a first selected slot-offset of a plurality of slot-offsets of a time synchronized channel hopping protocol, communicating, by a gateway node, a first message with a primary network node in a primary network, the primary network node part of a plurality of nodes communicating using the time synchronized channel hopping protocol;
- and
- during a second selected slot-offset of the plurality of slot-offsets of the time synchronized channel hopping protocol, listening, by the gateway node, for a second message from a secondary network node in a secondary network, the secondary network node communicating using a carrier sense multiple access protocol by communicating during wake-up intervals, wherein the wake-up intervals of the secondary network node are synchronized with the second selected slot-offset.
