Because of the limitation of 6-layer depth in the ZigBee network, it is not effective to establish chain network utility directly. And even the chain network is established by improving the protocol stack, the delay of information transmission will increase, which results in the unreliable problem. In view of this, a virtual chain network was proposed and developed based on the modified node which was composed of the ZigBee transparent transmission module and Arduino controller. This remote virtual chain network could be established and managed online, which also had the features of the original ZigBee network. By using the advantages of ZigBee network, such as Ad-Hoc network, routing forwarding, unvarnished transmission, the virtual chain network has higher transmission efficiency and a lower time delay. At the same time, the chain network can manage dynamically by lengthening and shortening the chain as required. The proposed method of establishing ZigBee virtual network chain network can be widely used in the systems of intelligent transportation, smart grid and intelligent lighting.
