Abstract: Embodiments disclosed herein relate to enabling direct wireless device-to-device communication between sleepy end devices (SEDs) of a mesh (e.g., Thread®) network. A router may forward packets between end devices of the mesh network. However, if the router is not available, SEDs may not be able to communicate with each other using a mesh protocol. Embodiments presented herein enable end devices of the mesh network to communicate directly, without a router. Some embodiments are directed to changing a role of an end device to temporarily act as a router for a particular target end device. The role change may be based on a trigger event and may be temporary until a target action is performed by the target end device. In some embodiments, the end devices continue to operate as SEDs and use coordinated sampled listening techniques to communicate via the mesh protocol.

Abstract: Systems and methods for coordinating data sampling among devices include a set of electronic devices that may periodically sample energy data from a smart meter according to sample timing information. The sample timing information may specify a set of times to sample energy data for each electronic device. The set of electronic devices may take turns in sampling energy data from the smart meter so that individual electronic devices may reduce power consumption by sampling less frequently. A server may determine the sample times for the electronic devices and may instruct the electronic devices to sample energy data. Additionally, each individual electronic device may leave and/or join wireless communication networks less frequently than if each individual electronic device performed every sample. Accordingly, the coordinated sampling may decrease the radio resource usage and/or bandwidth usage of any individual electronic device.

Abstract: The present disclosure relates to techniques for wireless communication between electronic devices in a wireless network, such as a mesh wireless network. For example, a first electronic device may include processing circuitry that is configured to cause a transceiver of the first electronic device to transmit to a second electronic device in a wireless network an indication of time slots. The processing circuitry may cause at least a portion of the transceiver to enter a low power state during one or more times outside the time slots and cause the transceiver to exit the low power state to transmit or receive wireless signals during the time slots.
