SIMULTANEOUS CONTROL OF A SUBNET OF NODES IN A WIRELESS NETWORK
A system for simultaneous control of a subset of nodes in a wireless network includes a network controller and a plurality of nodes that are communicatively coupled to the network controller. The network controller transmits a custom Zigbee unicast message to a node of the subset of nodes that is assigned as a point guard node upon receiving an instruction to control one or more nodes of the subset of nodes. The point guard node receives the custom Zigbee unicast message and generates an InterPAN broadcast message based on a payload of the custom Zigbee unicast message. The point guard node broadcasts the InterPAN broadcast message as a one hop broadcast message to all the nodes in the radio range of the point guard node. The receiving nodes whose identifiers are present in the payload of the InterPAN broadcast message act on the instruction to change a status thereof.
