ZigBee network establishing method and device

Abstract

The embodiment of the invention provides a ZigBee network establishing method and device, belonging to the network technology field. The method comprises: a coordinator performs channel scanning, and obtaining an optimal channel according to the channel scanning result, wherein the optimal channel is a channel having a minimal congestion degree and is configured to establish a first ZigBee network; detecting whether there is a second ZigBee network or not, if detecting there is a second ZigBee network, determining the network feature parameters of the first ZigBee network obtained in advance is the same as the obtained network feature parameters of the second ZigBee network or not, and obtaining a determination result; establishing the first ZigBee network based on the determination result so as to avoid the networking confusion of a coordinator renewedly building a first ZigBee network having the consistent network feature parameters to the already existed second ZigBee network to reduce the internetwork crosstalk.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a method and device for establishing a ZigBee network. Background technique [0002] Although ZigBee technology has many excellent features in wireless sensor networks, a series of problems may still occur in ZigBee networks in practical applications. After the coordinator node establishes the network and establishes the network with the routing node, various hardware and software failures may occur during operation, such as: protocol stack system crash or memory overflow, power supply exhaustion, physical collision, etc. cause the coordinator node to restart , after the coordinator node restarts unexpectedly, the coordinator node will rebuild a ZigBee PAN (Personal Area Network) network according to the original program, because the program inside the coordinator has not changed before and after the restart, so it must be started according to the first time Similarly, ...

Problems solved by technology

After the coordinator node establishes the network and establishes the network with the routing node, various hardware and software failures may occur during operation, such as: protocol stack system crash or memory overflow, power supply exhaustion, physical collision, etc. cause the coordinator node to restart , after the coordinator node restarts unexpectedly, the coordinator node will rebuild a ZigBee PAN (Personal Area Network) network according to the original program, because the program inside the coordinator has not changed before and after the restart, so it must be started according to the first time Similarly, create a new network according to the original network parameters and process. The preset network parameters of the network to be created are exactly the same as those of the original network. , which will cause great interference to the original network. If the terminal nodes in the original network do not carry out strict network access control, they may be induced to go into the newly built network, resulting in network confusion.
