Problems solved by technology
[0002] In the prior art, hardware manufacturers only improve the quality of gateways, but do not consider the load balancing problem between multiple gateways, which makes some gateways in the two adjacent gateways work under high load for a long time. Some other gateways are in an idle state, causing the node devices under the high-load gateway to be in a high-latency state for a long time. If a new node device is connected to the high-load gateway, the communication network will be further deteriorated. surroundings
Moreover, the gateway is in a high-load working state, and the aging of the gateway is aggravated due to the need to continuously receive and reply to node devices

Embodiment Construction
[0020] see figure 1 , in one embodiment, it discloses a kind of load balancing method for wireless internet of things, comprises the following steps:
[0021] S1. The first gateway requests the node device list from the cloud, and the cloud returns the node device list of the first gateway; the second gateway requests the node device list from the cloud, and the cloud returns the node device list of the second gateway;
[0022] S2. The node device is powered on and initialized. If the node device has a device identifier, the node device broadcasts a real-name discovery request. The first gateway searches the routing table of the node device. If it exists, it responds, and the node device obtains the first gateway. address; the node device initiates a real-name connection request after receiving the response from the first gateway, and sends a subscription request if the real-name connection of the node device succeeds, and the first gateway subscribes to the cloud in its own i...

The invention relates to a load balancing method for wireless Internet of things, which comprises the following steps: S1, a gateway requests a node device list from the cloud, and the cloud returns the node device list; S2, the node device goes online through the gateway; S3, the gateway finds that the node device belongs to a potential device and records the node device in a potential device list; S4, the node device list and the potential device list of the gateway are updated according to the online condition of the gateway; S5, the cloud receives the node device list and the potential device list, which are sent via the gateway; it is determined whether the node device needs to replace the connected gateway according to the load situation of the gateway and the number of the potentialdevices; and if needing to replace, the cloud issues a gateway replacing instruction; S6, after the node device receives the gateway replacing instruction, the to-be-connected gateway address is replaced according to the instruction; and a real name connection request is reissued. The method balances the load of the gateway, and avoids the problem that the load is uneven, resulting in aged gateway and shortened service life.
Description
technical field [0001] The disclosure belongs to the communication field of the Internet of Things, and in particular relates to a load balancing method for the wireless Internet of Things. Background technique [0002] In the prior art, hardware manufacturers only improve the quality of gateways, but do not consider the load balancing problem between multiple gateways, which makes some gateways in the two adjacent gateways work under high load for a long time. Some other gateways are in an idle state, causing the node devices under the high-load gateway to be in a high-latency state for a long time. If a new node device is connected to the high-load gateway, the communication network will be further deteriorated. environment. Moreover, the gateway is in a high-load working state, and the aging of the gateway is aggravated due to the need to continuously receive and reply to node devices. Contents of the invention [0003] In order to solve the above problems, the presen...
