Patent number: 11924738Abstract: Techniques for managing connections in a mesh network that includes multiple provisioners are described. In an example, a computer system receives, from a first device set up as a first provisioner in the mesh network, a first identifier of a third device of the mesh network. The computer system also receives, from a second device set up as a second provisioner in the mesh network, the first identifier of the third device. The computer system generates an association between the third device and the first device based at least in part on a determination that the third device is to be reached exclusively via the first device. The computer system also generates a message about an action to be performed by the third device and sends, based at least in part on the association, the message to the first device.Type: GrantFiled: January 29, 2020Date of Patent: March 5, 2024Assignee: Amazon Technologies, Inc.Inventors: Soon Hyeok Choi, VenkatRaghavan VijayaRaghavan, Bowei Feng, Lakshmi Venkatraman

Patent number: 11871222Abstract: Techniques for managing connections in a mesh network are described. In an example, a device sends, to a plurality of devices of the mesh network, one or more messages requesting an action to be performed by a first device of the mesh network. The device determines, based at least in part on data about the mesh network, that the first device is to be reached via a second device of the mesh network. The second device being a single hop away from the device. The device establishes a peer-to-peer connection with the second device and receives, over the peer-to-peer connection, a response of the first device to the message.Type: GrantFiled: January 29, 2020Date of Patent: January 9, 2024Assignee: Amazon Technologies, Inc.Inventors: Bowei Feng, Soon Hyeok Choi, Lakshmi Venkatraman

Patent number: 11570790Abstract: A method for communicating in a wireless sensor network (WSN) is described. Using control logic, a first wireless transceiver is caused to transmit a wireless packet to a node in a wireless sensor network. The control logic bases its causing on a transmission coinciding with a break in transmission for a second wireless network, such that the transmission from the first wireless transceiver does not coincide with transmissions made on the second wireless network. Time synchronized channel hopping (TSCH) slot frames for wireless packet transmission in the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing TSCH. Wake up sequence transmissions for the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing coordinated sampled listening (CSL).Type: GrantFiled: November 11, 2019Date of Patent: January 31, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ariton E.
