Hierarchical network architecture of wireless Internet-of-Things home system and networking communication method thereof

Abstract

The invention relates to a hierarchical network architecture of a wireless Internet-of-Things home system and a networking communication method of the hierarchical network architecture. The hierarchical network architecture of the wireless Internet-of-Things home system comprises a set of master control equipment, intermediate wifi nodes and information household appliances. The master control equipment is used for forwarding control instructions of a user to the information household appliances managed by the master control equipment and feeding control results and the current states of the information household appliances back to a set of user terminal equipment. The intermediate wifi nodes are used for packaging the received control instructions into data frames in preset protocol formats and sending the data frames to the information household appliances corresponding to the destination addresses. Moreover, the intermediate wifi nodes are used for unpackaging the received data frames and forwarding effective information carried in the data frames to the master control equipment. The intermediate wifi nodes are provided with data receiving ports and data forwarding ports adopting different protocols. The information household appliances are used for executing corresponding operations according to the received control instructions. The hierarchical network architecture of the wireless Internet-of-Things home system has the advantages of being flexible in operation and large in coverage area.

Description

technical field [0001] The invention relates to a hierarchical network architecture of a wireless IoT home system and a networking communication method thereof, which belong to the field of computer network communication technology and the Internet of Things technology, and are widely applicable to home systems constructed using wireless network communication technology and the Internet of Things technology. Background technique [0002] The wireless IoT home is the embodiment of IoT under the influence of the Internet.
