  • Publication number: 20200359453
    Abstract: Disclosed is a method for electing a root node in a mesh network, comprising the steps of: S1) when it is determined that there is no root node in the mesh network, all devices separately broadcast and transmit real-time signal strengths between the devices and a router; S2) all devices separately perform a first scanning, and each device elects, according to received real-time signal strengths between the other devices and the router and the real-time signal strength between the device and the router, a device having a maximum real-time signal strength as a root node candidate and broadcasts and transmits the same; and S3) all devices separately perform another scanning, and each device elects, according to the received root node candidates respectively elected by the other devices, a root node candidate having a maximum signal strength as a new root node candidate and broadcasts and transmits the same again until a unique root node is elected.

  • Patent number: 10693714
    Abstract: A communication method for Wi-Fi Internet of Things equipment, which is used for Wi-Fi Internet of Things main control equipment to send control information to Wi-Fi Internet of Things controlled equipment, in which Wi-Fi Internet of main control equipment and Wi-Fi Internet of Things controlled equipment complete pairing, and acquire a MAC address and a communication key of each other; the Wi-Fi Internet of main control equipment sends control information to the Wi-Fi Internet of Things controlled equipment by loading a private information structure in a Wi-Fi unicast packet or multicast packet; and the Wi-Fi Internet of Things controlled equipment sends confirmation information to the Wi-Fi Internet of Things main control equipment after receiving the control information.

  • Publication number: 20200137671
    Abstract: The invention discloses a Wi-Fi networking method, the method comprises: an address definition in a MAC layer data structure comprises a target destination address and a group address of a Wi-Fi device; adding Wi-Fi devices in a same frequency band and having a same group address to a same Wi-Fi network. In the invention, one group address specifies one Wi-Fi network; any Wi-Fi devices in the same frequency band, as long as they have the same group address, are considered as being in the same network and establish one Wi-Fi network; any device is in a peer role, and there is no substantial connection relationship; any Wi-Fi device may freely join or leave the network; the number of devices in this network may tend to be infinite, the range of the network may tend to be infinitely wide, and various network topologies of different complexities are supported.
