Embodiment Construction

[0036] see figure 1 , is a flow chart of a sensor network networking method provided by an embodiment of the present invention, including:

[0037] 101: Obtain the short address of the network node and the location identifier of the parent node.

[0038] The short address has a one-to-one correspondence with the 64-bit extended unique identifier EUI-64 of the network node, and is uniformly managed and allocated by the network coordinator, also known as the gateway, and can be a prime number that uniquely identifies the network node.

[0039] The network coordinator can maintain a pool of addresses that includes all unassigned short addresses.

[0040] The network node can obtain the node information of at least one neighbor node in the network through the neighbor discovery protocol, and the node information includes the EUI-64, short address, location identifier and node type of the neighbor node; the node type can be network coordination device, router or end device, etc. ...

Abstract

An embodiment of the invention discloses a sensor network networking and routing method, a network node and a system. The method comprises obtaining location markers of short addresses and father nodes of the network node, wherein the short addresses are prime numbers for identifying the network node only; generating location markers of the network node according to the location markers of the short addresses and the father nodes; sending location register message and registering the location markers of the network node to a network coordinator; and receiving location confirmation message coming from the network coordinator. By means of the technical scheme, the problem that the existing wireless sensor network does not support heterogeneous distribution and movability of the node, or a routing table needs generating and maintaining, a network resource is consumed and node consumption is high is solved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a sensor network networking and routing method, network node and system. Background technique [0002] Sensor networks are widely used in environmental and ecological monitoring, health monitoring, home automation, and traffic control. The sensor network is a distributed intelligent network system that is composed of a large number of sensor nodes with wireless communication and computing capabilities deployed in the active area and can monitor the physical or environmental conditions of different locations through self-organization. For example, the home wireless sensor network is responsible for collecting basic physical data in the home, such as temperature, humidity, harmful gas detection, etc., and can also change the home environment. Sensor networks can operate in a stand-alone environment or be connected to the Internet through a gateway, allowing users to access the...
