ProtocoType: when netrelaydenode broadcasts, it can represent that the frame data is broadcast data by fixing a certain value (for example: 0);
MAC: physical address of netrelaydenode node;
checking: the sum is accumulated from all fields Version to ArecayN.
In the exemplary embodiment of the present invention, the EndNode monitors broadcast data of the netrelayde node, and if broadcast information (or broadcast data) of multiple netrelayde nodes is monitored at the same time, the optimal netrelayde node may be selected to establish a connection after comprehensive judgment by DelayX, creeyn, and ArelayN.

In an exemplary embodiment of the present invention, the division of the delay levels (network delay levels) may be as shown in table 1 below:
TABLE 1
| Network delay level | Time delay range | Description of the classes |
| 1 | 1～30ms | Very fast with almost no perceived delay |
| 2 | 31～50ms | Good without obvious delay condition |
| 3 | 51～100ms | Normal, with slight pause |
| 4 | ＞100ms | Poor and obvious jamming, and the phenomena of packet loss and disconnection |
In an exemplary embodiment of the present invention, the selection logic of the relay node (i.e. the first home device in the second type of node device) may also be as shown in fig. 3, and specifically may sequentially include the following selection logics:
1. firstly, selecting the NetRelayNode with the minimum DelayX according to the filtering of delay levels (such as 4 levels);
2. selecting the NetRelayNode with the minimum ArelayN again;
3. then selecting the NetRelayNode with the maximum CrelayN;
4. if a plurality of NetRelayNodes still exist, the NetRelayNode with the strongest signal strength (closest distance) is preferentially selected.
In an exemplary embodiment of the present invention, the establishing a communication connection with the first home device according to the private mesh protocol may include: the communication connection is established based on the proprietary mesh protocol customized by the link layer of the 802.11 protocol.
In the exemplary embodiment of the present invention, the connection communication between the EndNode and the NetRelayNode may be a link layer customized private mesh protocol based on an 802.11 protocol, and the private mesh protocol consumes less resources, so that the load of the module can be reduced, and the requirement on the module hardware can be reduced. Meanwhile, the private mesh communication can stagger the communication frequency band of the current router, and communication is performed through other channels, so that relay communication can be ensured, and interference on the original wifi signal can be avoided.

In an exemplary embodiment of the present invention, the method may further include: in the process of communication according to the private mesh protocol, a question-answer mode is adopted between the current household appliance and the first household appliance to keep the communication state.
In an exemplary embodiment of the present invention, as shown in fig. 4, the communication flow according to the private mesh protocol may include:
1. after monitoring the broadcast data of the NetRelayNode, the EndNode selects the optimal NetRelayNode to initiate connection, and the connection is initiated by the EndNode;
2. and the NetRelayNode saves EndNode related information after receiving the EndNode connection request. Meanwhile, the NetRelayNode replies ack to EndNode;
3. the EndNode enters a monitoring mode after receiving the ack of the NetRelayNode, the NetRelayNode judges whether to continue broadcasting according to the resources, and if the resources are sufficient, the broadcast content data is updated and the broadcasting continues;
4. the private mesh communication process adopts a question/answer mode, firstly, the NetRelayNode always detects the communication state with the router, the NetRelayNode periodically initiates a question in an idle state, and then EndNode responds. As the number of netrelaydenodes relaying endnodes increases, the "question/answer" period per EndNode increases. The broadcast and the question of the NetRelayNode need to be periodically switched according to the actual situation;
5. if the connection is initiated, the NetRelayNode does not receive the connection request of EndNode, and the NetRelayNode does not reply ack; meanwhile, the EndNode can start overtime waiting after initiating a connection request, and if the ack of the corresponding NetRelayNode is not received in 10S, the EndNode monitors the broadcast of other NetRelayNodes again;
6. if the NetRelayNode receives the EndNode connection request, the related information of the EndNode is stored, and the ack is replied at the same time. But EndNode does not receive the message within the timeout period of 10S, then EndNode listens to other NetRelayNode broadcast again. When NetRelayNode periodically asks questions, if EndNode does not answer for more than 3 times, deleting the information corresponding to EndNode, and then updating the broadcast content;
7. starting from the EndNode originating connection (that is to say with the exception that the broadcast follows the "broadcast content format"), all the same-letter interactions follow the above "post-connection communication frame format".
In an exemplary embodiment of the present invention, if the current home device is a first node device, the method may further include: and after a connection request to the first household appliance is initiated, monitoring the broadcast information of a second type of node equipment except the first household appliance again when the reply of the first household appliance is not received within a preset time length.
In an exemplary embodiment of the present invention, netrelaydenode may maintain a periodic "question/answer" connection with EndNode, and if EndNode has not received a "question" of netrelaydenode within 30s (this time, the length is greater than the maximum "question/answer" period), endNode may clear previous information about netrelaydenode and re-listen and select a suitable netrelaydenode to relay to the internet.
In an exemplary embodiment of the present invention, if the current household device is a second node device, the method may further include: after receiving the connection request and before establishing connection with the first type node equipment, storing relevant information of the first type node equipment, and periodically asking questions of the first type node equipment;
and when the response of the first type node equipment to the question is not received for n times continuously, deleting the relevant information of the first type node equipment, updating the content of the broadcast information, and then broadcasting the broadcast information outwards periodically.
In the exemplary embodiment of the present invention, the netrelaydenode may periodically obtain updates itself and the server network delay DelayX. Meanwhile, the NetRelayNode and the EndNode keep periodic 'questioning', if the 'questioning' (the power failure of the equipment is possible) is not responded for 3 times continuously, or the EndNode requires active disconnection, corresponding EndNode information is deleted, and CrelayN and ArelayN in the NetRelayNode broadcast content are updated at the same time, wherein the CrelayN is added with 1, and the ArelayN is subtracted with 1.

after determining that the current household appliance belongs to the first type of node equipment, periodically acquiring network connection information with a server, and if the current household appliance can normally perform network connection with the server and the network delay DelayX with the server is within a preset normal range, replacing the role of the current household appliance with the second type of node equipment;

In an exemplary embodiment of the present invention, if the netrelaydenodeon suddenly loses network connection, delayX > 100ms, creatayn =0, arelayn =0, and after broadcasting is performed 3 times again, the broadcast is turned off, and meanwhile, the connected endnodeon is notified to disconnect to listen and select other suitable netrelaydenodeons to relay the internet, and then the role of the connected endnodeon is changed to endnodeon.
In the exemplary embodiment of the present invention, the EndNode itself may also periodically acquire network connection information with the server, and if it is able to connect normally and the Delayx is normal, inform NetRelayNode and disconnect the connection with it, and then perform internet communication through a direct route, and if CRelayN >0, it may be used as the NetRelayNode to broadcast information to the outside at the same time.
