A network apparatus coupled to a plurality of nodes. The nodes are clustered into a plurality of groups. The network apparatus includes a storage component and a controller. The storage component is configured to store a plurality of group numbers corresponding to the groups and a plurality of node numbers corresponding to the nodes. The controller is configured to transmit a broadcast packet to all of the nodes. The broadcast packet includes a local network broadcast message. The local network broadcast message includes operating information. The local network broadcast message corresponds to at least one of the group numbers and the node numbers. Each of the nodes determines whether to dismiss the operating information of the broadcast packet according to the local network broadcast message of the broadcast packet.

Intelligent illumination system, network apparatus and operating method thereof

A network system includes first nodes and a second node. Each first node is directly communicatively connected to the second node, or each first node is indirectly communicatively connected to the second node through another first node. The second node includes a network layer and an application layer. When a new node desires is joining the first nodes, the network layer sends an update signal including first network address information of the new node. The application layer is configured to connect to a database and perform an authentication on the first network address information of the new node based on a node list in the database. When the new node passes the authentication, the application layer stores the update signal in the database.

Network system and communication device therein

A network system includes a plurality of network groups. Each of the network groups includes at least one node. The at least one node is configured for transmitting a beacon response according to a beacon request transmitted by a new node. When the at least one node of the at least one of the network groups transmits the beacon response, at least another one of the network groups is in a sleep state, and the new node connects with the at least one node of the at least one of the network groups according to the beacon response. A connection method of the network system is also disclosed herein.
