Abstract: A first node in a TSCH network may receive a message-initiation packet from a second node on the TSCH network. Based on information in the message-initiation packet, the first node may determine a transmission time for a message content packet that is associated with the message-initiation packet. The first node may generate or modify a node-specific transmission delay that indicates a backoff associated with the second node. The node-specific transmission delay may indicate a quantity of backoff time slots during which the first node delays initiating a transmission with the second node. If the first node receives, during the node-specific transmission delay, an additional packet intended for the second node, the first node may queue the additional packet until after the node-specific transmission delay is completed.

Abstract: In some aspects, a channel hopping sequence for communication on a mesh network is generated. The hopping sequence may include multiple channels assigned to respective positions in the hopping sequence. In some cases, a first channel is assigned to a first position such that the first channel may transmit communications in a first transmission mode, such as a low-bandwidth transmission mode. In addition, an additional channels adjacent to the first channel is also assigned to the first position such that the combination of the first channel and additional channel may transmit communications in a second transmission mode, such as a high-bandwidth transmission mode. In some cases, a whitelist is determined based on the assigned channels. The whitelist may indicate channels that do not conflict with the assigned channels during transmission of a communication. In addition, channels may be assigned to the hopping sequence based on the whitelist.

Abstract: A system for determining a communication mode utilized by a transmitting node to transmit a data packet in a mesh network is provided. For example, a receiving node operates in a base communication mode to detect a pilot p of a data packet. The pilot prefix contains a signal with a predetermined frequency. In response to determining that the pilot prefix is detected, the receiving node detects a communication mode used to transmit the data packet based on preamble signals that are contained in a preamble of the data packet and are received after the detected pilot prefix. Once the communication mode is detected, the receiving node receives and processes the remaining portion of the data packet using the detected communication mode.

Abstract: A system for switching between different communication modes by network nodes according to a time-division schedule to transmit and receive data packets is provided. For example, a transmitting node is configured to determine a scheduled communication mode of an upcoming time division according to a time-division schedule, and transmit a data packet in that time division when the scheduled communication mode matches a selected communication mode supported by both the transmitting node and a receiving node. The receiving node operates in a scheduled communication mode specified for a current time division by the time-division schedule and determines whether a header of the data packet is detected in the current time division. If not, the receiving node switches to a second scheduled communication mode specified for the subsequent time division by the time-division schedule to detect the header of the data packet in a subsequent time division.

Abstract: A system for selecting a communication mode for a transmitting node to communicate with a receiving node in a mesh network is provided. For example, a transmitting node can gather mode selection data that describe communication conditions of the transmitting node and the receiving node. Based on the mode selection data, the transmitting node can determine a first white list of modes that can be used by the transmitting node to successfully transmit data packets to the receiving node. The transmitting node also determines a second white list of modes that can be used by the receiving node to send acknowledgment packets successfully to the transmitting node. The transmitting node further identifies overlapped modes between the first and second white lists of modes. The transmitting node can then select one of the overlapped modes for transmitting data packets to the receiving node.
