Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the drawings and specific embodiments of the description. In the following description, all nodes in the wireless sensor network are divided into root nodes N root and sensor node N o , where the root node N root It refers to the node with the function of public network gateway among the nodes of the whole network, which has the function of routing and aggregation. The sensor node N o It does not have the routing function, but only has the simple forwarding function, and the sensor node connected to only one sensor node is specifically called the edge terminal node N e .

[0037] The networking method of the wireless sensor network provided by the present invention is mainly realized through the following steps:

[0038] Step A10, in the wireless sensor network, remove the root node N root Each sensor node other than N oi After power-on and starting up, broadcast detection to the adjacent s...

Abstract

The invention discloses a networking method for a wireless sensor network, which comprises the following steps that sensor nodes establish connection and reception power tables with adjacent sensor nodes in a broadcast detection way; the sensor nodes converge towards a root node according to a connection situation of the root node; the connection tables and reception power tables of the nodes are combined in sequence to generate corresponding link feedback table data packets in a converging process; the data packets are gathered to be uploaded to the root node; the root node dispatches node transmitting-receiving sequence numbers of main links and branch links where the sensor nodes are located for the sensor nodes according to link feedback tables and networking rules; and networking of the sensor nodes is conducted according to the dispatched node transmitting-receiving sequence numbers. According to the method, link transmitting-receiving sequence numbers are issued to end nodes by taking advantages of the strong calculation processing capacity of the root node, plan networking of all the nodes in a whole network is realized, the circuit configuration of the nodes is greatly reduced, a communication process is simplified, and the networking is optimized.

Description

technical field [0001] The invention relates to a wireless sensor network, in particular to a networking method of the wireless sensor network. Background technique [0002] Wireless Sensor Network (WSN for short) refers to a wireless network composed of a large number of stationary or moving sensors in a self-organizing and multi-hop manner. The monitoring information of perceived objects is widely used in information systems for monitoring and controlling objects and environments [0003] The current wireless sensor network is most commonly based on wireless self-organizing network technology to realize networking. This technology requires high node capabilities and complex networking. The specific reasons are as follows: [0004] (1) Unpredictable dynamic changes in the network topology, and complex topology establishment. [0005] In the wireless self-organizing network, node failure / failure / restart / discovery due to the influence of environmental changes, node power-on...
