Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of a configuration method for relay communication according to an embodiment of the present invention is shown, and specifically may include the following steps:

and step 101, connecting a primary router or a relay node through a station node of the Wi-Fi module.

In a specific implementation, the embodiments of the present invention may be applied to a mobile terminal, for example, a mobile phone, a tablet computer, a smart wearable device (such as a smart watch), and the like.

These mobile terminals may be installed with Windows phone, Android, IOS, Windows, and other operating systems, configured with a Wi-Fi (WIreless-Fidelity) module, and may be connected to a WIreless node as a relay node to forward a WIreless signal.

A Wi-Fi module is also called a serial port Wi-Fi module, belongs to an Internet of things Transmission layer, can convert a serial port or TTL (transistor-transistor logic level) signal into an embedded module which accords with a Wi-Fi wireless network communication standard, and is internally provided with a wireless network Protocol IEEE802.11b.g.n Protocol stack and a TCP/IP (Transmission Control Protocol/Internet Protocol) Protocol stack.

In a particular implementation, Wi-Fi modules typically have three functions: station, softAP, P2P.

Wherein station: which means devices connected to a wireless network, can communicate with other devices inside or outside the wireless network through an AP (wireless access point).

softAP: the function of using the application to realize the AP is shown, so that the mobile terminal can be used as a route to link other stations.

P2P (Peer-to-Peer): also known as Wi-Fi Direct, can support two Wi-Fi devices to connect directly and communicate without an AP.

In the embodiment of the present invention, the mobile terminal may be used as a relay node to connect to a higher-level device, which may be a router or a relay node, that is, the relay node may be hooked after the relay node to form a tree-like relay network.

If the mobile terminal is a relay node of the first level, the mobile terminal can be connected with a router of the first level through a station node of the Wi-Fi module.

If the mobile terminal is a second-level relay node or a relay node below the second level, the mobile terminal can be connected with a first-level relay node through a station node of the Wi-Fi module.

In one embodiment, a getWifiState () method in a WifiManager can be called to detect whether the mobile terminal turns on a station node of Wi-Fi.

When the state node is detected to be started, whether the state node is connected with the wireless node or not can be detected by calling an Application Programming Interface (API) Interface getNetworkInfo () provided by the connectivity manager, and using the connectivity manager.

If the returned NetworkInfo object is not null and isConnected () is true, the wireless node is confirmed to be connected.

When the situation node is detected not to be started or not to be connected with the wireless node, prompt information of the connected wireless node is generated, such as 'please turn on the Wi-Fi and connect a router or a relay'.

Step 102, detecting a relay level of the relay node.

In a specific implementation, after the mobile terminal accesses the network as a relay node, the relay level at which the mobile terminal is currently located may be identified.

The relay node of the first stage may be referred to as a root node, and two stages of relay nodes are connected with each other, where the relay node of the previous stage is a parent node of the relay node of the next stage, and relatively speaking, the relay node of the next stage is a child node of the relay node of the previous stage.

In one embodiment, each level of relay node may maintain one relay configuration information, in which information such as routing path, relay level, login information (such as service set identification SSID and password) and the like may be recorded.

In this embodiment, the relay level at which the relay node is located may be set as the first level.

And according to a preset specification, requesting relay configuration information to a router or a relay node at the upper stage.

If the device at the upper level is a router, and the router does not set the specification, the request of the mobile terminal is ignored.

And if the equipment at the upper level is the relay node which has set the standard, responding to the request of the mobile terminal and returning the relay configuration information.

And when the request is successful, extracting the relay level of the relay node at the upper stage from the relay configuration information.

And on the basis of the relay level of the relay node at the upper stage, calculating the relay level where the relay node is located to replace the first stage.

Further, the mobile terminal may add one to the relay level of the relay node at the previous stage, so as to obtain the relay level at which the mobile terminal is currently used as the relay node.

For example, if the relay level of the relay node at the previous stage is the second stage, the relay level of the mobile terminal as the relay node is the third stage, and the default first stage is modified to the third stage.

When the request fails, the relay level as the relay node is determined to be the first level. Of course, the above-mentioned detection method of the relay level is only an example, and when implementing the embodiment of the present invention, other detection methods of the relay level may be set according to actual situations, for example, requesting the relay level to the router or the relay node at the previous stage, if the request fails, setting the relay level as the first stage, if the request succeeds, calculating the current relay level on the basis of the relay level of the relay node at the previous stage, and the like, which is not limited in this embodiment of the present invention. In addition, besides the above relay level detection method, a person skilled in the art may also adopt other relay level detection methods according to actual needs, and the embodiment of the present invention is not limited to this.

And 103, selecting a target channel according to the relay level.

According to the electromagnetic interference theory, electromagnetic waves of non-self equipment are interference sources, the interference sources emit electromagnetic energy, the electromagnetic energy is transmitted to sensitive equipment through a certain propagation path, and the sensitive equipment responds to interference in a certain form and generates an interference effect.

In the embodiment of the invention, Wi-Fi antennas in the mobile terminal are closely spaced, the mobile terminal is also closely spaced with the mobile terminal, the maximum interference is from radiation electromagnetic coupling of the antenna of the mobile terminal or the surrounding antennas, and the problems of low data forwarding capacity and poor relay performance can be caused.

When the signal source is closer to the interference frequency, the coupling value is larger, and the interference is larger, so that in order to reduce electromagnetic interference, a target channel can be selected at a relay level to select a frequency range without mutual interference, and the problems of lower data forwarding capacity and poorer relay performance caused by channel interference caused by channel setting of a relay function are solved.

In one embodiment of the present invention, step 103 may comprise the following sub-steps:

and a substep S11, querying a channel where the router or the relay node at the previous stage is located as an uplink channel.

In the Android system, WiFi service is a core service responsible for WiFi function, and the WiFi statemachine subsystem is responsible for maintaining various types of status information of WiFi.

The state information includes channel information of the router or the relay node at the previous stage, and thus, the first channel of the router or the relay node at the previous stage can be acquired by calling the mwifitatemachine.

And a substep S12 of determining a band type of the uplink channel.

In practical application, the working frequency bands of the first channel of the router or the relay node are different, and mainly comprise a 2.4G frequency band (2.412GHz-2.484GHz) and a 5G frequency band (5.735GHz-5.835GHz)

Of these, most routers or relay nodes commonly use wireless technology operating at 2.4Ghz, using the (fourth generation) 802.11n standard, and the fifth generation Wi-Fi technology operating at a 5Ghz high band, using the 802.11ac protocol standard.

And a substep S13, when the relay level is the first level, calculating a target channel which does not interfere with the uplink channel according to the frequency band type.

If the relay level of the mobile terminal as the relay node is the first level, the mobile terminal is connected with the router, and the target channel can be directly set according to the frequency band type of the uplink channel of the router.

And when the channel type is a 2.4G frequency band, shifting the uplink channel by N channels as a target channel, wherein N is a positive integer and is more than or equal to 5.

As shown in fig. 2, the map of the 1-14 channels in the 2.4G frequency band is a gradient matrix, 3 independent frequency bands are divided from the angle of the frequency band, the range of each independent frequency band is approximately 22MHz, because adjacent frequency bands have frequency values equal to each other in a crossing manner, the channels in each independent frequency band have interference, and the specific frequency bands are as follows:

a first area: 1-5 channels

And a second zone: 6-10 channels

And (3) three zones: 11-14 channels

For example, the frequency shared by channel 1 and channel 2 is 2406-2423, at this time, if the channel of the uplink channel of the router or relay node at the previous stage is set to 1 and the target channel of the relay node is set to 2, there is a frequency identical interval and interference.

From the angle of frequency band isolation, divide into 5 isolation intervals altogether, the channel in the isolation interval does not have the interference, and specific interval is as follows:

one type is as follows: 1. 6, 11

The second type is as follows: 2. 7, 12

Three types are as follows: 3. 8, 13

Four types: 4. 9. The following is a description of the preferred embodiment

And five types are as follows: 5. 10. the method of the present invention

Therefore, when the channel type is the 2.4G band, the uplink channel may be shifted by at least 5 channels as the target channel.

Assuming that X is an uplink channel of a router or a relay node at the previous stage, and Y is a target channel of the relay node (i.e., a mobile terminal), the two satisfy the following relation:

y is more than or equal to X +5, or, Y is less than or equal to X-5

Wherein X, Y is a positive integer, and when Y <1 or Y >13, Y is invalid and needs to be discarded.

When the channel type is 5G frequency band, the uplink channel is shifted by M channels as a target channel, where M is a positive integer, such as 1, 2.

As shown in fig. 3, since there is no crossover in the 5G frequency band, the uplink channel of the router or the relay node at the previous stage and the target channel of the current relay node are not the same channel, i.e. interference can be substantially avoided.

And a substep S14, when the relay level is at or below the second level, detecting a channel in which an adjacent relay node is located as an adjacent channel.

In an embodiment of the present invention, if the relay node sets the same service set identifier and password to facilitate roaming, the relay node that is the same as the service set identifier of the mobile terminal may be searched, and a channel where the relay node is located may be detected as an adjacent channel.

And a substep S15 of calculating a target channel which does not interfere with the uplink channel and the adjacent channel according to the frequency band type.

If the relay level of the mobile terminal serving as the relay node is the second level or below, the mobile terminal is connected with the relay node, and a target channel can be set according to the frequency band type of the uplink channel of the nearby relay node.

And when the channel type is a 2.4G frequency band, shifting the uplink channel by N channels as candidate channels, wherein N is a positive integer and is more than or equal to 5.

When the channel type is 5G frequency band, the uplink channel is shifted by M channels as candidate channels, where M is a positive integer, such as 1, 2.

When the candidate channel is the same as the adjacent channel, it may indicate that the relay node to which the current adjacent channel belongs and the current relay node belong to the same relay network, and there may be interference, and therefore, the interference coefficient may be calculated by using the signal information of the relay node to which the adjacent channel belongs.

For the case where the candidate channel is different from the adjacent channel, the adjacent channel may be ignored.

In one example, the number and/or signal strength of relay nodes to which adjacent channels belong may be detected, and the interference coefficient may be calculated by configuring a weighted sum or the like.

The number and/or the signal strength are/is positively correlated with the interference coefficient, that is, the interference coefficient is larger when the number is larger and the signal strength is stronger, and conversely, the interference coefficient is smaller when the number is smaller and the signal strength is lower.

Then, a target channel is selected from the candidate channels according to the interference coefficient, and in general, the target channel is selected from the candidate channels with the smallest interference coefficient.

It should be noted that, when the number of candidate channels is one, the channel with the smallest number or the channel with the largest number, which is farthest from the candidate channel, is set as the candidate channel.

Therefore, from the angle of frequency band isolation, 5 isolation intervals are divided, and channels in the isolation intervals do not have interference, and the specific intervals are as follows:

one type is as follows: 1. 6, 11

The second type is as follows: 2. 7, 12

Three types are as follows: 3. 8, 13

Four types: 4. 9, 13

And five types are as follows: 1. 5, 10

For the fourth and fifth classes, assuming that the uplink channels are 9, 5, and the uplink channels are shifted by 5 channels, resulting in 4, 14 (drop), 0 (drop), and 10 channels, respectively, 13, 1 channels may be added as candidate channels.

Assuming that Y is an uplink channel of a router or a relay node at the previous stage, and Z is a target channel of the relay node (i.e. a mobile terminal), the two satisfy the following relation:

z is more than or equal to Y +5, or Z is less than or equal to Y-5

Wherein Y, Z is a positive integer, and when Z <1 or Z >13, Z is invalid and needs to be discarded.

And 104, starting the softAP node of the Wi-Fi module according to the relay level so as to connect the application terminal and/or the relay node at the next level on the target channel.

If the station node of the Wi-Fi module of the mobile terminal is connected to the router or the relay node of the previous stage, a relay instruction can be sent to the Wi-Fi module according to the relay level, the softAP node is started, and the application terminal and/or the relay node of the next stage are/is connected through the softAP node.

Wherein, the application terminal may refer to a terminal that realizes its own function, for example, an intelligent electric rice cooker, an intelligent air conditioner, an intelligent water heater, and the like.

It should be noted that the mobile terminal may be used as a relay node, and may also be used as an application terminal to implement functions such as browsing a web page, playing a game, and playing a network video.

In one embodiment of the invention, a channel of the softAP node can be determined, which generally has no interference with the router and other relay nodes, and therefore, the relay instruction can be issued on the channel.

In a specific implementation, the frequencies corresponding to different channels are:

and when the relay level is the first level, receiving login information input by a user, wherein the login information comprises a service set identifier and a password.

In this case, the User may be prompted at a UI (User Interface) to enter the SSID and password of the relay (i.e., mobile terminal).

And if the user inputs the SSID and the password in the UI, using the SSID and the password, and otherwise, using a default SSID and a default password.

When the relay level is the second level or more, the login information is extracted from the relay configuration information of the relay node at the upper level, the login information between the father node and the son node is kept the same, and under the condition that the invalid network signal is poor (such as less than-90 DB), roaming can be started, and other adjacent relay nodes are automatically connected by adopting the same login information.

If the login information is obtained, the softAP node of the Wi-Fi module can be started according to the target channel, the service set identification and the password so as to broadcast the service set identification in the target channel.

In a specific implementation, freq (channel), SSID, and password are written into a hostapd.

hostapd-d hostapd.conf

The freq, SSID and password can be validated.

After the relay instruction is sent, the broadcast frame sent by the relay node (i.e. the mobile terminal) carries the SSID, and after the SSID is scanned, other terminals can use the SSID and the password for connection.

In a specific implementation, the relay node (i.e., the mobile terminal) may be regarded as an AP, which periodically broadcasts a Beacon frame, and the SSID of the relay node (i.e., the mobile terminal) can be obtained by scanning the Beacon frame by other station devices.

When an application request sent by one or more electronic devices (application terminals and/or relay nodes at the next stage) for the SSID is received, a response message challenge text is returned to the one or more electronic devices.

When a connection request sent by one or more electronic devices is received, whether the password in the connection request is the same as a preset password or not is verified, and if yes, the one or more electronic devices are accessed.

And 105, configuring relay communication parameters according to the relay level so as to support communication between the station node and the softAP node.

In the embodiment of the invention, the relay nodes of different relay levels have different relay communication parameters, so that the station node and the softAP node can communicate with each other, and the softAP node is connected with the next-level application terminal and/or relay node due to the fact that the station node is connected with the first-level wireless node, so that the previous-level router or relay node can communicate with the next-level application terminal and/or relay node, and the relay function is realized.

In one embodiment of the present invention, step 105 may comprise the sub-steps of:

and a sub-step S21 of turning on the packet forwarding function.

In a specific implementation, a packet forwarding function may be started through an echo attribute value to support forwarding of a data packet between a station node and a softAP node:

echo 1>/proc/sys/net/ipv4/ip_forward

packet forwarding is the process of allowing packets to be forwarded from one terminal to another.

In the embodiment of the invention, a packet forwarding function is opened, and the data packet is supported to be mutually forwarded between the station node and the softAP node.

And a substep S22, when the relay level is the first level, setting the configuration information of the address translation function NAT.

In practical application, the configuration information of an Address translation function NAT (network Address translation) can be called to the Wi-Fi module through the system Address table service iptables, and the NAT can automatically modify the source IP Address and the destination IP Address of the IP packet to disguise the IP Address of the application terminal.

Of course, prior routing tables may also be purged before sending the routing tables and NAT.

The configuration information of the Iptables and NAT configuration is as follows:

# remove old rules (clear previous routing tables)

iptables-F

iptables-t filter-F

iptables-t nat-F

#Bring up NAT rules

iptables-t nat-A POSTROUTING-s 192.168.49.0/24-d 0.0.0.0/0-jMASQUERADE

Wherein, assuming that the IP segment of the relay (i.e. the mobile terminal) is 192.168.49.0, the sending Bring up NAT rules can repackage and unpack the data packet with 192.168.49.0/24 network segment as the source address, and disguise as the source address of 0.0.0.0/0.

And a substep S23, when the relay level is the second level or below, allocating an IP address from the relay node of the previous level, and establishing a routing path between the relay nodes of each level.

In a specific implementation, an IP address may be dynamically assigned to a relay node at or below the second level.

In one embodiment, the total address space may be divided into multiple segments or multiple sub-domains, each relay node may continue to allocate its assigned address to a sub-node from which the application terminal does not have a sub-node, so no address needs to be allocated.

The mobile terminal as a relay node has an address pool, i.e. a set of addresses, the address pool capacity of a relay node at or below the second level is determined from its parent node, which calculates the address pool capacity by the following formula:

C_skip(d)＝1+C_m×(L_m-d-1) R_m＝1

C_skip(d)＝(1+C_m-R_m-C_m×R_m ^Lm-d-1)/(1-R_m) R_m≠1

wherein, C_skip(d) An offset value indicating that a parent node having a relay level d determines when assigning an address, an address pool capacity of a corresponding child node, C_mIndicating the maximum number of subnodes, L, that the relay node can receive_mRepresenting the maximum depth of the network (relay level),R_mrepresents the maximum number of subnodes that the relay node can receive, and d represents the node depth (relay level).

The depth d of a father node is increased by 1 when the network is accessed, the depth of a coordinator is defined as 0, C_m、L_m、R_mThese three parameters may be provided by the user describing the size and general form of the network.

Calculating the offset C_skip(d) And then, the father node determines the network address according to the type of the network-accessing child node.

If the child node is a relay node, the address can be calculated by adopting the following formula:

A_n＝A_p+C_skip(d)×(n-1)+1 1≤n≤R_m

wherein A is_pIs the network address of a father node, n is the node applying for network access and is the second child relay node, A_nAnd obtaining the network address for the nth network access sub-relay node.

In the embodiment of the present invention, a relay routing table may be maintained in each relay node, and in the relay routing table, when each relay node enters the network, its assigned address and a parent-child relationship between the relay node and other relay nodes may be recorded, and when each relay node exits the network, its assigned address is deleted, so that the parent-child relationship and addresses between relays at each level may constitute a routing path of relays at each level.

And a substep S24 of inquiring the IP address of the router or the relay node of the previous stage.

Substep S25, setting the IP address of the router or the relay node at the upper stage as the gateway address of the domain name system DNS

In the embodiment of the invention, on one hand, an address table service iptable in the system can be called to send a gateway address of a DNS (Transmission Control Protocol) based on a TCP (Transmission Control Protocol) to a Wi-Fi module;

the command format is:

iptables-tnat-I PREROUTING-I (Relay device name) -p tcp-dport 53-j DNAT-to-destination (gateway)

On the other hand, the address table service iptable in the system can be called, and a gateway address of the DNS based on UDP (Open system interconnection) is sent to the Wi-Fi module.

The command format is:

iptables-tnat-I PREROUTING-I (Relay device name) -p udp-dport 53-j DNAT-to-destination (gateway)

When the relay node of which the relay level is the first level, the gateway address of the domain name system DNS is set as the gateway address of the router.

When the relay level is the second level or a relay node below the second level, the gateway address of the domain name system DNS is set as the IP address of the relay node at the upper level.

As described above, the DNS gateway addresses of TCP and UDP are added to the relay device (i.e., the mobile terminal), and after the DNS is configured, the input uniform resource locator URL is transferred step by step and is finally resolved by the DNS server, thereby implementing network communication.

The embodiment of the invention is characterized in that a mobile terminal is provided with a Wi-Fi module, a softAP node of the Wi-Fi module is started through a router or a relay node at the upper stage of a station node of the Wi-Fi module to connect an application terminal and/or a relay node at the lower stage, relay communication parameters are configured according to the current relay level to support communication between the station node and the softAP node, the mobile terminal is realized as the relay node, the relay node is hung behind the relay node to form a multi-stage relay network, the structure level of the network is expanded, the number of the relay nodes is increased, the number of the connected nodes is increased, and under the condition that intelligent household appliances, handheld terminals and other devices are increased, the newly-added devices can be connected with a relay and normally use wireless signals.

As shown in fig. 4, it is assumed that there are a living room, a kitchen, two bedrooms (including a main bed and a secondary bed) and a study room in a house, wherein the main bed is close to the study room, and the secondary bed is close to the kitchen.

In this example, the router 42 is placed in the living room, the router 42 accesses the base station 41, and as a wireless node, broadcasts a Wi-Fi signal.

Due to the large living room area and the wall blockage, Wi-Fi signals in the main bed, the secondary bed, the study and the kitchen are weak, so that the mobile terminal 432 can be placed in the living room, the mobile terminal 431 can be placed near the main bed, the mobile terminal 4313 can be placed near the study, the mobile terminal 4321 can be placed near the secondary bed and the kitchen, the mobile terminal 43213 can be placed near the kitchen, and the mobile terminal 43211 can be placed near the secondary bed.

In the living room:

The mobile terminal 432 accesses the route 42 through the station node and starts the softAP node as a relay node of the first level to relay the Wi-Fi signal to other parts of the living room (e.g., the balcony), respectively.

The portable computer 433 is used as an application terminal to access the route 42 for the user to perform work, entertainment and other processes in the living room.

The mobile terminal 4321 accesses the mobile terminal 432 through the station node and starts the softAP node as a relay node of the second level to relay the Wi-Fi signal to the sub-horizontal, kitchen.

Referring to fig. 5, a flowchart illustrating steps of another embodiment of a method for configuring relay communication according to an embodiment of the present invention is shown, and the method is applied to a mobile terminal, where the mobile terminal is configured with a Wi-Fi module, and the method specifically includes the following steps:

and step 501, receiving a data packet sent by the application terminal and/or the relay node of the next level through the softAP node.

When the application terminal communicates with a target device (such as a web server) of an external network, the data packet generated by the application terminal is transmitted step by step through the relay node until the data packet is sent to the target device.

Step 502, forwarding the data packet from the softAP node to the station node.

In specific implementation, as the packet forwarding function is started, the data packet can be forwarded from the softAP node to the station node, so that forwarding of the data packet inside the relay node is realized.

Step 503, sending the data packet to the router or the relay node at the upper stage through the station node according to the communication configuration parameter.

In practical application, the data packet may be processed according to communication configuration parameters of different relay levels, so as to implement relay communication.

In one embodiment of the present invention, step 503 may include the following sub-steps:

and a substep S31, when the data packet has the uniform resource locator URL, inquiring the gateway address of the domain name system DNS.

And a substep S32, sending the data packet to the upper level router or the relay node through the station node according to the gateway address.

In the embodiment of the invention, the URL is analyzed when the application terminal accesses the webpage and the like.

If the gateway address of the DNS of the mobile terminal is the IP address of the relay node at the upper stage, the packet for resolving the URL can be forwarded to the relay node at the upper stage.

And the gateway address of the DNS of the relay node of the current level is the IP address of the relay node of the previous level, the packet for resolving the URL may be forwarded to the relay node of the previous level.

And until the D NS reaches the first-stage relay node, the gateway address of the D NS is the IP address of the router, the data packet for resolving the URL can be forwarded to the router, and the router sends the data packet to a server for providing domain name resolution for the external network and maps the URL to the IP address.

In another embodiment of the present invention, step 503 may include the following sub-steps:

and a substep S33, converting the source address in the data packet from the IP address of the application terminal to the IP address of the mobile terminal when the relay level is the first level.

And a substep S34 of transmitting the packet disguised from the IP address of the mobile terminal to the router at the upper stage through the station node.

For the relay node in the first level, the source address (i.e. the IP address of the mobile terminal) in the packet, such as 192.168.49.0, may be disguised as the IP address of the mobile terminal itself, such as 0.0.0.0, based on the NAT configuration information, and forwarded to the router.

and a substep S35, when the relay level is at or below the second level,

In the embodiment of the present invention, for the relay node at the second level or below the second level, the data packet may be directly forwarded to the relay node at the upper level.

And step 504, receiving the data packet sent by the router or the relay node at the upper stage through the station node.

When the target device of the external network communicates with the application terminal, the data packet generated by the target device is transmitted to the relay node (i.e. the mobile terminal) hop by hop until the data packet is sent to the application terminal.

Step 505, forwarding the data packet from the station node to the softAP node.

In specific implementation, as the packet forwarding function is started, the data packet can be forwarded to the softAP node from the node station, so as to implement forwarding of the data packet inside the relay node.

Step 506, the data packet is sent to the next-level application terminal or the relay node through the softAP node according to the communication configuration parameters.

In one embodiment of the present invention, step 506 may include the following sub-steps:

and a substep S41, converting the destination address in the data packet from the IP address of the mobile terminal to the IP address of the application terminal when the relay level is the first level.

And a substep S42, when the relay level is the second level or below, inquiring a source address in the data packet to obtain the IP address of the application terminal.

And a substep S43 of querying a target path from the IP address of the mobile terminal to the IP address of the application terminal through the relay routing tables between the relay nodes at each stage.

And a substep S44, inquiring the IP address of the application terminal or the relay node of the next stage in the target path.

And a substep S45, sending the data to the next-stage application terminal or relay node by the softAP node according to the IP address of the next-stage application terminal or relay node.

For the relay node of the first stage, the second IP address of the station node from which the packet originates may be determined, and the first IP address corresponding to the second IP address is looked up in the routing table, so that the packet may be forwarded to the softAP node to which the first IP address belongs.

For the relay node in the first level, the destination address in the packet (i.e. the IP address of the mobile terminal itself), for example, 0.0.0.0, may be translated into the IP address of the application terminal, for example, 192.168.49.0, based on the configuration information of the NAT. For each stage of relay node, since a plurality of relay nodes can be connected, that is, there are a plurality of routes to the application terminal, when a data packet is sent down, the destination address in the data packet can be queried to determine the application terminal to which the data packet is sent.

And inquiring a relay routing table to obtain a target path which can be routed to the application terminal, inquiring the IP address of the next-stage mobile terminal or the relay node from the path, and forwarding the data packet to the IP address.

If the next level is the application terminal, the data packet is sent to the application terminal through the softAP node, and the application terminal performs corresponding processing, such as loading a webpage, playing a video and the like.

If the next stage is a relay node, the softAP node transmits the packet to the relay node, and the relay node can continue to perform downward relay communication.
