All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In embodiments of the present invention, the term "module" generally refers to: hardware, a combination of hardware and software, and so forth. For example, a module may be a process running on a processor, an object, an executable, a thread of execution, a program, and so on. Both an application running on a processor and the processor can be a module. One or more modules may be located in one computer and/or distributed between two or more computers.
In the embodiment of the present invention, "first", "second", and the like are only used for distinguishing different objects, and should not constitute any limitation to the embodiment of the present invention.
The embodiment of the invention provides a wireless mesh network access method and device, computing equipment and a computer readable storage medium. Specifically, the wireless mesh network access method and apparatus provided in the embodiments of the present invention are suitable for (integrated in) a computing device, and the computing device may be a Personal computer, a server, a mobile device (for example, a mobile phone, a Personal Digital Assistant (PDA), a tablet computer), a router, a base station, and the like.
In the method and apparatus for accessing a wireless Mesh network according to the embodiments of the present invention, both a device (i.e., an Isolate AP) and a Mesh AP (Access Point)) to be accessed to the wireless Mesh network are routers.
As shown in fig. 1 and fig. 2, the technical solution of the embodiment of the present invention is as follows:
a wireless Mesh network access point (Mesh AP)101, i.e., a wireless Mesh network networking device that has accessed a wireless Mesh network, sets information of the wireless Mesh network in its ProbeResponse wireless message.
A device (i.e., a wireless Mesh network networking device that is not accessing a wireless Mesh network) 102 to be accessed to the wireless Mesh network performs wireless scanning (sends a broadcast ProbeRequest frame), and analyzes Mesh information in a ProbeResponse frame received by the device (i.e., the standalone AP)102, thereby implementing discovery of a neighbor node (Mesh AP)101 of the wireless Mesh network.
A device (i.e., the peer node (Mesh AP)102 to be accessed to the wireless Mesh network evaluates the neighbor node (Mesh AP)101 and selects an optimal neighbor node (Mesh AP) 101.
The device (Isolate AP)102 to be accessed to the wireless mesh network requests association to the wireless mesh network and associates to the optimal neighbor node after receiving the response of the optimal neighbor node, thereby implementing access to the wireless mesh network.
The wireless mesh network access method and the wireless mesh network access device provided by the embodiment of the invention realize the rapid networking of the wireless mesh network by utilizing the existing wifi hardware platform on the basis of protocols such as 802.11a/b/g/n/ac/ax and the like.
The technical scheme provided by the embodiment of the invention can be compatible with most of the existing wifi hardware platforms, and has the advantages of higher networking speed and stronger self-repairing capability.
As shown in fig. 3 to fig. 7, a wireless mesh network access method provided by an embodiment of the present invention includes the following steps:
a device (Isolate AP)102 to be accessed to a wireless mesh network adds an Isolate ie field in the vendorIE area of its 802.11 protocol probe request frame, where the Isolate ie field is a data structure that serves as an identifier to identify the particular Isolate AP 102.
In step 301, a device (i.e., the standalone AP)102 to be accessed to the wireless mesh network sends wireless mesh network access point probe information. The wireless Mesh network Access Point detection information is a wireless scanning (detection) signal, and is used for detecting a wireless Mesh network Access Point (Mesh AP) 101. Specifically, a device (i.e., the standalone AP)102 to be accessed to the wireless mesh network periodically transmits a broadcast probe request frame (wireless mesh network access point probe information) to all wireless channels supported by it. After receiving the ProbeRequest frame, the Mesh AP101 of the wireless Mesh network access point searches whether the ProbeRequest frame includes an isolateIE field, and if so, responds to a unicast ProbeResponse frame, wherein the isolateIE field is data of a predetermined position in the ProbeRequest frame.
Step 302, the device (i.e., the standalone AP)102 to be accessed to the wireless mesh network receives the first feedback information corresponding to the wireless mesh network access point detection information. The first feedback information is feedback information sent by the wireless Mesh network access point (Mesh AP)101 in response to the wireless Mesh network access point probe information. The first feedback information includes wireless mesh network information.
Step 303, selecting the wireless mesh network access point 101 meeting the predetermined condition according to the first feedback information. Specifically, after receiving the ProbeResponse frame sent by the Mesh AP101, the Isolate AP102 parses the bssid, mac, ip, radio, cost, hops, clusterID, channel, RCPI, and other information in the ProbeResponse frame, and initializes a neighbor node (wireless Mesh network access point) 101 with the information, and inserts the information into a neighbor node list (a data set including at least one wireless Mesh network access point information). The Isolate AP102 selects the best (meeting the predetermined condition) neighbor node from the neighbor node list.
The step 303 includes:
step 3031, analyzing the first feedback information to obtain at least one wireless mesh network access point information, where the first feedback information is a data packet having a predetermined data structure, and if the wireless device that sends the first feedback information is a wireless access point (the wireless mesh network access point) 101 in the wireless mesh network, the predetermined location of the first feedback information includes the wireless mesh network access point information.
Step 3032, selecting the wireless mesh network access point 101 meeting the predetermined condition according to at least one piece of wireless mesh network access point information.
The step 3031 comprises the following steps:
step 30311, determining whether the first feedback information includes wireless mesh network information, and generating a determination result;
step 30312, obtaining the wireless mesh network access point information when the judgment result is that the first feedback information includes the wireless mesh network information. That is, in a case where the data of the predetermined position of the first feedback information includes wireless mesh network access point information, the wireless mesh network access point information is acquired.
The step 3032 comprises the following steps:
step 30321, a quality assessment value for establishing a wireless mesh network connection with said wireless mesh network access point 101 is calculated.
Specifically, the cost of each neighbor node in the neighbor list of the Isolate AP102 (a quality assessment value of the wireless mesh network connection established between the Isolate AP102 and each neighbor node in the neighbor list) is calculated.
The calculation formula of the quality evaluation value cost is as follows: the cost is rssi _ cost + radio _ cost + backhaul _ cost;
here, rssi _ cost is f1(RCPI), radio _ cost is f2(radio), and backshaul _ cost is f3(cost _ xxx).
Specifically, for the quality evaluation value cost _ n of the nth-level neighbor node in the wireless mesh network, cost _ n is f1(RCP _ n _ n-1) + f2(Radio _ n-1) + f3(cost _ n-1), where n is the number of node levels corresponding to the neighbor node in the wireless mesh network, and when the neighbor node accesses the internet by means of wired connection, n is 1, and then cost1 is 0, as shown in fig. 8.
The quality assessment value cost of the Mesh AP101 accessing the network through the network line is 0.
For f1(RCPI), RCPI is the receive channel power parameter.
If RCPI <15, f1(RCPI) is 80;
if the RCPI is 15-25, f1(RCPI) is 40;
if the RCPI is 25-33, f1(RCPI) is 20;
if RCPI >33, f1(RCPI) is 0.
For f2(radio), radio represents the radio band supported by the neighbor Mesh AP 101.
If the current neighbor only supports the 2.4G band, f2(radio) is 40;
if the current neighbor only supports the 5G frequency band, f2(radio) is 20;
if the current neighbor and the 2.4G and 5G supported bands are supported, f2(radio) is 15.
For f3(cost _ xxx), cost _ xxx is the link quality assessment value between the current neighbor Mesh AP101 and its superordinate node.
If cost _ xxx <20, f3(cost _ xxx) ═ cost _ xxx;
if the cost _ xxx is 20-100, f3(cost _ xxx) is 20;
if the cost _ xxx is 100-200, f3(cost _ xxx) is 40;
if cost _ xxx >200, then f3(cost _ xxx) 65535.
Specifically, for the quality evaluation value cost _ n of the nth-level neighbor node in the wireless mesh network, cost _ n is f1(RCP _ n _ n-1) + f2(Radio _ n-1) + f3(cost _ n-1), where n is the number of node levels corresponding to the neighbor node in the wireless mesh network, when the neighbor node accesses the internet through wired connection, n is 1, when cost1 is 0, when n is 2, cost2 is f1(RCP _2_1) + f2(Radio1) + f3(cost1), when n is 3, cost3 is f1(RCP _3_2) + f2(Radio2 f3(cost2), and so on, as shown in fig. 8.
After establishing a link with the optimal neighbor node, the Isolate AP102 becomes the Mesh AP101, and after becoming the Mesh AP101, sets the cost (the link evaluation value with the uplink node) thereof into the cost field of the vendorIE area of the ProbeRequest frame thereof, namely, ProbeResponse- > VendorIE- > cost.
Step 30322, selecting said wireless mesh network access point 101 based on said quality assessment value. Specifically, the neighbor node with the minimum quality evaluation value is selected as the optimal neighbor node.
The compliance of the wireless mesh network access point 101 with the predetermined condition corresponds to the quality assessment value of the wireless mesh network access point 101 being the smallest one.
Step 304, accessing to the wireless mesh network through the wireless mesh network access point 101. Specifically, the Isolate AP102 requests to associate with an optimal neighbor node (optimal Mesh AP), the optimal Mesh AP accepts the association of the Isolate AP102, and the Isolate AP102 successfully associates and accesses the wireless Mesh network.
After the above steps are performed, the Isolate AP102 becomes the Mesh AP101, and when the Mesh AP101 is disconnected from the wireless Mesh network, the Mesh AP101 becomes the Isolate AP 102.
After the above steps are performed, the Mesh AP101 periodically detects whether it is connected to a network (including wired access and wireless access), and if not, it becomes the Isolate AP102, and the above steps are repeatedly performed. That is, if a Mesh AP101 is disconnected from the wireless Mesh network, it automatically transitions to the Isolate AP 102.
After the Mesh AP101 is changed, the Mesh AP101 adds a Mesh ie (a data structure including key information such as bssid, mac, ip, radio (radio band), cost (link quality evaluation value), hops (Mesh network hop count), clusterID (network group identifier) and the like) in the vendorIE area of the 802.11 protocol ProbeResponse frame of the Mesh AP 101.
After becoming Isolate AP102, Isolate AP102 adds an Isolate IE (a data structure used as an identification of a particular IsoateAP) in the vendorIE area of its 802.11 protocol ProbeRequest frame.
The step 304 includes:
step 3041, sending a wireless mesh network access request to said wireless mesh network access point 101;
step 3042, receiving second feedback information corresponding to the wireless mesh network access request;
step 3043, establishing a communication connection with the wireless mesh network access point 101 according to the second feedback information, so as to access the wireless mesh network.
The method further comprises the steps of:
recording the accessed wireless mesh network information for adding to feedback information corresponding to the received other wireless mesh network access point detection information.
In the technical solution provided in the embodiment of the present invention, since the Isolate AP102 collects information of the neighbor Mesh APs 101, then selects an optimal Mesh AP101 from the neighbor Mesh APs 101, and associates the Mesh AP101 with the optimal Mesh AP101, the Isolate AP102 is converted into the Mesh AP101 after successfully accessing the wireless Mesh network. Based on this, the Isolate AP102 selects the wireless mesh network access point 101 that is optimal with the wireless mesh network to construct the wireless mesh network, and thus it is possible to make the time taken to construct the wireless mesh network less, i.e., to enable fast networking, and the constructed wireless mesh network is more stable.
In order to better implement the above method, correspondingly, the embodiment of the present invention further provides a wireless mesh network access apparatus, which may be integrated (adapted) in a computing device.
As shown in fig. 9, a wireless mesh network access apparatus (device (Isolate AP) to be accessed to a wireless mesh network) 102 provided by an embodiment of the present invention includes a sending module 901, a receiving module 902, a selecting module 903, and a connecting module 904.
A device (Isolate AP)102 to be accessed to a wireless mesh network adds an Isolate ie field in the vendorIE area of its 802.11 protocol probe request frame, where the Isolate ie field is a data structure that serves as an identifier to identify the particular Isolate AP 102.
Said sending module 901 of the device (Isolate AP)102 to be accessed to the wireless mesh network is used to send wireless mesh network access point probe information. The wireless Mesh network access point detection information is a wireless scanning (detection) signal, and is used for detecting a wireless Mesh network access point (Mesh AP) 101. Specifically, the sending module 901 of the device (i.e., the independent AP)102 to be accessed to the wireless mesh network is configured to periodically send a broadcast probe request frame (wireless mesh network access point probe information) to all wireless channels supported by the device. After receiving the ProbeRequest frame, the Mesh AP101 of the wireless Mesh network access point searches whether the ProbeRequest frame includes an isolateIE field, and if so, responds to a unicast ProbeResponse frame, wherein the isolateIE field is data of a predetermined position in the ProbeRequest frame.
The receiving module 902 of the device to be accessed to the wireless mesh network (i.e., the standalone AP)102 is configured to receive the first feedback information corresponding to the wireless mesh network access point detection information. The first feedback information is feedback information sent by the wireless Mesh network access point (Mesh AP)101 in response to the wireless Mesh network access point probe information. The first feedback information includes wireless mesh network information.
The selecting module 903 is configured to select the wireless mesh network access point 101 meeting the predetermined condition according to the first feedback information. Specifically, after the Isolate AP102 receives the ProbeResponse frame sent by the Mesh AP101, the selecting module 903 is configured to parse the bssid, mac, ip, radio, cost, hops, clusterID, channel, RCPI, and other information in the ProbeResponse frame, initialize a neighbor node (wireless Mesh network access point) 101 with the information, and insert the information into a neighbor node list (a data set including at least one wireless Mesh network access point information). The selection module 903 of the Isolate AP102 is configured to select an optimal (meeting the predetermined condition) neighbor node from the neighbor node list.
The selecting module 903 is configured to analyze the first feedback information to obtain at least one piece of wireless mesh network access point information, where the first feedback information is a data packet with a predetermined data structure, and if a wireless device that sends the first feedback information is a wireless access point in the wireless mesh network (the wireless mesh network access point 101), a predetermined location of the first feedback information includes the wireless mesh network access point information.
Specifically, the selecting module 903 is configured to determine whether the first feedback information includes wireless mesh network information, generate a determination result, and acquire the wireless mesh network access point information when the determination result indicates that the first feedback information includes the wireless mesh network information. That is, in a case where the data of the predetermined position of the first feedback information includes wireless mesh network access point information, the wireless mesh network access point information is acquired.
The selecting module 903 is further configured to select the wireless mesh network access point 101 meeting the predetermined condition according to at least one piece of wireless mesh network access point information.
In particular, the selection module 903 is further configured to calculate a quality assessment value for establishing a wireless mesh network connection with the wireless mesh network access point 101.
Specifically, the selection module 903 is configured to calculate a cost of each neighbor node in the neighbor list of the peer AP102 (a quality evaluation value of the wireless mesh network connection established between the peer AP102 and each neighbor node in the neighbor list).
The calculation formula of the quality evaluation value cost is as follows: the cost is rssi _ cost + radio _ cost + backhaul _ cost;
here, rssi _ cost is f1(RCPI), radio _ cost is f2(radio), and backshaul _ cost is f3(cost _ xxx).
Specifically, for the quality evaluation value cost _ n of the nth-level neighbor node in the wireless mesh network, cost _ n is f1(RCP _ n _ n-1) + f2(Radio _ n-1) + f3(cost _ n-1), where n is the number of node levels corresponding to the neighbor node in the wireless mesh network, when the neighbor node accesses the internet through wired connection, n is 1, when cost1 is 0, when n is 2, cost2 is f1(RCP _2_1) + f2(Radio1) + f3(cost1), when n is 3, cost3 is f1(RCP _3_2) + f2(Radio2 f3(cost2), and so on, as shown in fig. 8.
The quality assessment value cost of the Mesh AP101 accessing the network through the network line is 0.
For f1(RCPI), RCPI is the receive channel power parameter.
If RCPI <15, f1(RCPI) is 80;
if the RCPI is 15-25, f1(RCPI) is 40;
if the RCPI is 25-33, f1(RCPI) is 20;
if RCPI >33, f1(RCPI) is 0.
For f2(radio), radio represents the radio band supported by the neighbor Mesh AP 101.
If the current neighbor only supports the 2.4G band, f2(radio) is 40;
if the current neighbor only supports the 5G frequency band, f2(radio) is 20;
if the current neighbor and the 2.4G and 5G supported bands are supported, f2(radio) is 15.
For f3(cost _ xxx), cost _ xxx is the link quality assessment value between the current neighbor Mesh AP101 and its superordinate node.
If cost _ xxx <20, f3(cost _ xxx) ═ cost _ xxx;
if the cost _ xxx is 20-100, f3(cost _ xxx) is 20;
if the cost _ xxx is 100-200, f3(cost _ xxx) is 40;
if cost _ xxx >200, then f3(cost _ xxx) 65535.
Specifically, for the quality evaluation value cost _ n of the nth-level neighbor node in the wireless mesh network, cost _ n is f1(RCP _ n _ n-1) + f2(Radio _ n-1) + f3(cost _ n-1), where n is the number of node levels corresponding to the neighbor node in the wireless mesh network, and when the neighbor node accesses the internet by means of wired connection, n is 1, and then cost1 is 0, as shown in fig. 8.
After establishing a link with the optimal neighbor node, the Isolate AP102 becomes the Mesh AP101, and after becoming the Mesh AP101, sets the cost (the link evaluation value with the uplink node) thereof into the cost field of the vendorIE area of the ProbeRequest frame thereof, namely, ProbeResponse- > VendorIE- > cost.
The selection module 903 is further configured to select the wireless mesh network access point 101 according to the quality evaluation value. Specifically, the selecting module 903 is configured to select the neighbor node with the smallest quality evaluation value as the optimal neighbor node.
The compliance of the wireless mesh network access point 101 with the predetermined condition corresponds to the quality assessment value of the wireless mesh network access point 101 being the smallest one.
The connection module 904 is configured to access a wireless mesh network through the wireless mesh network access point 101. Specifically, the connection module 904 of the Isolate AP102 is configured to request to associate with an optimal neighbor node (optimal Mesh AP101), where the optimal Mesh AP101 accepts the association of the Isolate AP102, and the Isolate AP102 successfully associates and accesses the wireless Mesh network.
After the above steps are performed, the Isolate AP102 becomes the Mesh AP101, and when the Mesh AP101 is disconnected from the wireless Mesh network, the Mesh AP101 becomes the Isolate AP 102.
After the above steps are performed, the Mesh AP101 periodically detects whether it is connected to a network (including wired access and wireless access), and if not, it becomes the Isolate AP102, and the above steps are repeatedly performed. That is, if a Mesh AP101 is disconnected from the wireless Mesh network, it automatically transitions to the Isolate AP 102.
After the Mesh AP101 is changed, the Mesh AP101 adds a Mesh ie (a data structure including key information such as bssid, mac, ip, radio (radio band), cost (link quality evaluation value), hops (Mesh network hop count), clusterID (network group identifier) and the like) in the vendorIE area of the 802.11 protocol ProbeResponse frame of the Mesh AP 101.
After becoming Isolate AP102, Isolate AP102 adds an Isolate IE (a data structure used as an identification of a particular IsoateAP) in the vendorIE area of its 802.11 protocol ProbeRequest frame.
The connection module 904 is configured to send a wireless mesh network access request to the wireless mesh network access point 101, receive second feedback information corresponding to the wireless mesh network access request, and establish a communication connection with the wireless mesh network access point 101 according to the second feedback information, so as to access the wireless mesh network.
The device further comprises a recording module for recording the accessed wireless mesh network information for adding to the feedback information corresponding to the received other wireless mesh network access point detection information.
In the technical solution provided in the embodiment of the present invention, since the Isolate AP102 collects information of the neighbor Mesh APs 101, then selects an optimal Mesh AP101 from the neighbor Mesh APs 101, and associates the optimal Mesh AP101, the Isolate AP102 is converted into the Mesh AP101 after successfully accessing the wireless Mesh network. Based on this, the Isolate AP102 selects the wireless mesh network access point 101 that is optimal with the wireless mesh network to construct the wireless mesh network, and thus it is possible to make the time taken to construct the wireless mesh network less, i.e., to enable fast networking, and the constructed wireless mesh network is more stable.
