A networking method of mesh wireless sensor network based on Thread protocol

Abstract

The invention discloses a networking method of a mesh wireless sensor network based on a Thread protocol, which comprises the following steps: a mesh wireless sensor network is created; the mesh wireless sensor network comprises a routing node, a boundary router and a terminal node; the mesh wireless sensor network comprises a routing node, a boundary router and a terminal node. The border routersends an authentication request to the server, the authentication request requires the server to respond to and return user information and authentication information, and the border router sends thereturned information to all in-network routing nodes after receiving the returned information. When there is an access request, the authentication route is compared according to the authentication information and the access request information sent by the node to be accessed, and when the comparison passes, the node to be accessed is allowed to join the mesh wireless sensor network. By sending theverification information to each in-network routing node, the invention enables the new in-network node to be authenticated directly by the in-network routing node connected with any in-network routing node, thereby reducing the in-network authentication waiting time.

Description

technical field [0001] The invention relates to the technical field of wireless networking, in particular to a networking method for a mesh wireless sensor network based on the Thread protocol. Background technique [0002] The existing wireless sensor network is generally networked through the Zigbee protocol. The Zigbee protocol is a short-distance, low-power mesh network communication protocol based on IEEE802.15.4, which defines the network layer and application layer specifications. In the industrial field , commercial lighting and smart home fields have a wide range of applications. However, the Zigbee protocol does not define the network layer, and its application layer protocol is chaotic, that is, the protocol standards used by various manufacturers may not be consistent. Therefore, the products between manufacturers cannot be used in common before, resulting in certain restrictions on their use. [0003] In the wireless mesh sensor network under Zigbee technology,...
