Abstract: 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.

Abstract: A bingo gaming system, machine, and method include a main bingo game, a feature bingo game, a main reel game associated with the main bingo game, and a feature reel game associated with the feature bingo game. The main reel game simulates outcomes of the main bingo game. The feature reel game simulates outcomes of the feature bingo game. A feature bingo game may be triggered by a main bingo game outcome.

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.

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.

Abstract: 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.

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.
