摘要： An Internet of Things (IoT) networking authentication system and a method thereof are provided. The IoT networking authentication system includes an idle IoT apparatus and a networked IoT apparatus. The idle IoT apparatus encrypts a connection request according to a key to generate a connection request ciphertext and sends the connection request ciphertext. The networked IoT apparatus receives the connection request ciphertext and decrypts, according to the key, the connection request ciphertext to obtain the connection request. The networked IoT apparatus authenticates the idle IoT apparatus according to the connection request to generate an authentication result. The networked IoT apparatus determines, according to the authentication result and a networking condition, whether to allow the idle IoT apparatus to join an IoT network, so as to generate a connection response. The networked IoT apparatus outputs the connection response to the idle IoT apparatus.

摘要： A mesh network system adapted for a wireless access point includes multiple mesh network nodes, which are a root node, relay nodes, and leaf nodes. The root node is communicatively connected to the wireless access point. The relay nodes and the leaf nodes are configured to receive a downlink message having a downlink destination address. When one of the relay nodes that receives the downlink message determines that the downlink destination address fails to match its mesh network address, the relay node queries a routing table to find a next-hop node address directing to the downlink destination address and forwards the downlink message to the mesh network node corresponding to the next-hop node address. When one of the leaf nodes that receives the downlink message determines that the downlink destination address fails to match its mesh network address, the leaf node discards the downlink message.

摘要： An Internet of Things (IoT) network system and a networking method thereof are provided. The IoT network system is connected to a wireless access point and includes a plurality of network nodes and an idle node. The plurality of network nodes are communicatively connected to the wireless access point through a tree topology to form a first tree structure. In order to join the IoT network, when communication signal quality of the idle node with respect to the wireless access point is greater than a preset value, the idle node is communicatively connected to the wireless access point to form a root node of a second tree structure. When the communication signal quality of the idle node with respect to the wireless access point is not greater than the preset value, the idle node joins the IoT network by using one of network nodes in the first tree structure as a parent node.

摘要： A mesh network system suitable for connection to a cloud server is provided. The system includes: a first node device, configured to store a first private key and encrypt to-be-verified data according to the first private key to generate first encrypted data; and a second node device, configured to receive the first encrypted data and send the first encrypted data to the cloud server. After sending the first encrypted data, the second node device obtains, from the cloud server, second encrypted data generated by encrypting a first key according to the first public key. The second node device sends the second encrypted data to the first node device. The first node device decrypts the second encrypted data according to the first private key to obtain the first key from the second encrypted data, and performs encrypted communication with the cloud server according to the first key.

摘要： A root node selection system includes a plurality of idle nodes, and each idle node has a signal quality parameter. The each idle node is configured to broadcast a signal beacon and monitor other signal beacons, where each signal beacon carries the corresponding signal quality parameter. Any of the idle nodes is used as a to-be-selected node, and the to-be-selected node stores a signal quality table. The signal quality table includes a signal item and a rank item. The signal item includes the signal quality parameters. The rank item includes a plurality of ranks, and the ranks correspond to the signal quality parameters in the signal item in a one-to-one manner. The to-be-selected node serves as a root node of a mesh network based on that the rank corresponding to the signal quality parameter of the to-be-selected node is greater than a rank threshold.

摘要： A distribution network system and method. The distribution system has a plurality of communication channels and is connected to a mesh network. The mesh network uses one of the plurality of communication channels as a distributable network channel. The distribution network system includes an already-distributed network node and a to-be-distributed network node. The already-distributed network node is located in the mesh network and is configured to broadcast a mesh network beacon to the distributable network channel. The to-be-distributed node is configured to alternately monitor whether the mesh network beacon is detected on each communication channel. The to-be-distributed node outputs a network distribution request message to the already-distributed node according to the mesh network beacon, monitors whether a distribution network response message corresponding to the distribution network request message is detected on the distributable network channel, and joins the mesh network according to the distribution network response message.
