Abstract: Techniques for pacing messages in networked devices are described herein. A device receives a message to be sent to another device in a network of devices, determines when to send the message to the other device based on: a first pacing requirement, limiting messages that can be sent to first hop neighbors of the device to a first number of messages per unit of time; and a second pacing requirement limiting messages that can be sent to devices beyond the first hop neighbors of the device to a second number of messages, smaller than the first number of messages, per unit of time. The device sending the message to the other device at a time based at least in part on the first pacing requirement and the second pacing requirement.

Abstract: A method, a device, and non-transitory computer-readable storage medium are directed to synchronizing a local UTC of the device, operating in a cellular communication network, with the UTC, and includes monitoring for paging subframes transmitted at a paging subframe repeat interval; receiving the paging subframes; generating, based at least in part on the paging subframes received, paging triggers having a paging trigger repeat interval equal to the paging subframe repeat interval; and adjusting a reference timer of the electronic device based at least in part on the paging triggers.

Abstract: Techniques for acknowledging communications from multiple devices are described herein. For example, a device may broadcast a group acknowledgement message indicating that communications from multiple devices have been received by the device. Each acknowledgement in the group acknowledgement message may include a device identifier for a device that sent a communication (e.g., a Medium Access Control (MAC) address of the device, a hash of the MAC address of the device, etc.) and a communication identifier for the communication (e.g., a sequence number of the communication, a Cyclic Redundancy Check (CRC) code for the communication, etc.).

Abstract: Techniques for sharing resources between a radio access technology (RAT) modem (e.g., an LTE modem) and a processor-based radio (e.g., a software-defined radio) are described. In an example, operation of the RAT modem establishes an extended discontinuous reception mode (eDRX) cycle with a cellular system. The RAT modem sends eDRX scheduling information, that is based at least in part on the eDRX cycle, to the processor-based radio. Operation of the processor-based radio identifies paging opportunities (POs) of the eDRX cycle, based at least in part on the eDRX scheduling information. Operation of the processor-based radio manages usage of shared resources (e.g., transmit and receive amplifiers, digital signal processing elements, memory devices, elements of physical layer(s), and/or antenna(s), etc.). The managing may be based at least in part on the identified POs. The managing avoids conflicts between the RAT modem and the processor-based radio over the shared resources.

Abstract: Techniques for allocating event offsets within a period of transmission are described. A mains-powered device (MPD) may act as a “parent” to one or more battery-powered devices (BPDs). The MPD may assign “event offsets” to each BPD. The event offset is a time by which the BPD's timeslot is “offset” from the start of a periodic cycle of transmissions by the MPD. Thus, each event offset indicates a time that the BPD must be “awake,” i.e., operating its radio receiver and/or performing other functionality. A BPD may spend a substantial fraction of its time in a “sleep” mode, wherein less power is used and fewer functions are performed than during a period of that BPD's event offset. Another BPD may have a different event offset. Communications by the MPD with each child BPD may be substantially uniformly distributed over the period. To increase efficiency, groups of BPDs may receive multicasts.

Abstract: One embodiment of the present invention sets forth techniques for processing packets transmitted within a network in accordance with a network protocol. The techniques include receiving, by a network device in a mesh network, a type-length-value (TLV) element; determining, by the network device based on both a first type identified in a type field of the TLV element and a value in at least one sub-field of a value field of the TLV element, an expected length of the value field of the TLV element; and processing, by the network device, the value field up to the expected length.

Abstract: One embodiment of the present invention sets forth a technique for processing packets transmitted within a network in accordance with a network protocol. The technique includes determining a first expected length of a value field included in a type-length-value (TLV) element within a first frame of a first packet received over the network, wherein the first expected length is based on a type field included in the TLV element. The technique also includes processing a first portion of the value field based on the expected length of the value field in accordance with a first specification for a first version of the network protocol, without processing a second portion of the value field beyond the expected length of the value field.

Abstract: Techniques for sharing resources between a radio access technology (RAT) modem (e.g., an LTE modem) and a processor-based radio (e.g., a software-defined radio) are described. In an example, operation of the RAT modem establishes an extended discontinuous reception mode (eDRX) cycle with a cellular system. The RAT modem sends eDRX scheduling information, that is based at least in part on the eDRX cycle, to the processor-based radio. Operation of the processor-based radio identifies paging opportunities (POs) of the eDRX cycle, based at least in part on the eDRX scheduling information. Operation of the processor-based radio manages usage of shared resources (e.g., transmit and receive amplifiers, digital signal processing elements, memory devices, elements of physical layer(s), and/or antenna(s), etc.). The managing may be based at least in part on the identified POs. The managing avoids conflicts between the RAT modem and the processor-based radio over the shared resources.
