Abstract: A network configuration updating method having configuration stabilizing mechanism used in a mesh network system is provided. Network configuration information including father node identification information, child node identification information recorded in an assistance table, length information and a configuration information identification code is configured by each of node apparatuses to further broadcast a broadcast signal including the network configuration information. The broadcast signal of any other node apparatuses is received by each of the node apparatuses to determine that the broadcast signal includes the network configuration information according to the configuration information identification code, determine an initial position of the child node identification information according to the length information, and retrieve the father node identification information and the child node identification information.

Abstract: A wireless network operation method having power saving mechanism is provided. Packet storage states of node apparatuses are retrieved by a root node apparatus from an access point apparatus. For each of the node apparatuses, a node packet storage state table indicating the packet storage states is configured and a beacon signal including the node packet storage state table is broadcasted in an independent periodic broadcast time. For each of the node apparatuses, the beacon signals are received and the node packet storage state table included by the beacon signal is analyzed to update the node packet storage state table. For each of the node apparatuses entering a sleep mode, a predetermined schedule is performed to wake up to perform a packet transmitting process when the packet storage state of any one of the node apparatuses and the child node apparatus thereof has a storage indication level.

Abstract: A network nodes pairing method having an anti-spoofing mechanism is provided used in a mesh network system. Each of node apparatuses in the mesh network system uses group information of the mesh network system as a key to encrypt network system identification information and self-identification information to broadcast a beacon signal including encrypted information. A scan process is executed by a child node apparatus to select a target father node. A validity verification process is performed on the beacon signal of the target father node according to the group information so as to determine the target father node passes the validity verification process when the target father node and the child node apparatus has the same network system identification information and when the self-identification information of the target father node is valid. A pairing request signal is transmitted to the target father node to request for pairing.

Abstract: 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.

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.

Abstract: 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.
