Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings.
Due to the complex wireless medium environment, different functional frame structures are designed in the 802.11 wireless standard protocol to cooperate to adapt to the complex wireless network environment. The frames in the 802.11 protocol are divided into three types, namely management frames, control frames and data frames. Probe frames and beacon frames that are closely related to discovery and connection of the radio belong to the management frame. Fixed bits with determined functions and known word length are arranged in the management frame; and the system also comprises information elements with indefinite word length and expandability. The protocol frame may be divided into three parts, a mac header part, a frame body, and an FCS part. The mac header information mainly includes the type of the frame, the source address, the destination address, the BSSID, and the like. The FCS part performs error detection on the entire frame. The core part is a Frame Body (Frame Body). The data of the frame body is called fixed bits if fixed-length bits are used, and information elements (information elements) if the length is not fixed. While the new version of the 802.11 specification allows the definition of new information elements, the structure of which is as follows: consists of one byte of ID, one byte of length, and indefinite length information element data. As known from the standard, the invention designs a wireless router group management system capable of partner identification by defining an unused information element ID, sets the first byte of the data field of the information element as an operation byte, and then sets the variable-length byte as an information-carrying data byte.
Since partner identification (Companion Recognition) is a wireless router group system that never occurs, the core of the present invention is to design a frame structure and determine the flow of different operations. The definition of the frame operation flow needs to consider the actual application scenario. The scenes mainly needing to be processed comprise partner adding, partner existence confirming and eliminating, terminal entering into a service area, terminal connection service area WIFI, load balancing between partners and router network breaking.
The invention relates to a wireless router group management method, which sets the following information element data fields in a wireless protocol management frame: the first byte is set as an operation field, wherein the first bits (e.g. bit0-bit5) are partner identification operation bits for defining the operation content corresponding to the frame, and the operation content may include but is not limited to: searching for a partner operation, requesting to become a partner operation, requesting an identity authentication operation, a partner confirmation success/failure operation, whether a partner has an operation, confirming the existence operation, a replacement base station request operation, a replacement base station confirmation operation, a replacement base station feedback operation, a network connectionless operation; bit6 is an acknowledgment bit and bit7 is a retransmission bit. When bit7 is 1, it indicates that if the frame does not receive the acknowledgement information (bit6 is 1), retransmission is required, and the router sending the frame needs to maintain a retransmission timer, record the retransmission times, and accumulate the retransmission times in sequence from 0, but the retransmission times thresholds of different frames are different; when bit7 is 0, then this timer is not maintained.
In the invention, each router has a partner table and a terminal selection table, the partner table is used for storing information of all other partner routers in the wireless router group, including device MAC, survival confirmation field, load number and the like of the partner routers, and the terminal selection table is used for storing information of all terminals connected with the router, including device MAC and the like of the terminals.
The following specifically introduces business processes of partner adding, partner existence confirmation and elimination, terminal entering service area, terminal connection service area WIFI, load balancing among partners, router network disconnection and the like in the wireless router group respectively:
1. the partner joins, that is, when a router enters a service area formed by a wireless router group, as shown in fig. 1, the present invention includes:
step A1, the router entering the service area (called as the base station router for short) sends the seek partner frame to the periphery;
the partner identification operation bit of the partner frame is a partner searching operation, does not carry any field afterwards, has the length of 0, and is used for informing other routers with the partner identification function that a new router searches for a partner and enabling the partner router which has become the partner to update the corresponding confirmed survival field in the partner table;
step A2, other routers scan out a temporary MAC list composed of device MACs of all routers nearby sending and searching for a partner frame, then compare the temporary MAC list with each device MAC in the own partner table, if the device MAC in the temporary MAC list does not exist in the partner table and does not receive a request sent from the device MAC to become a partner frame, then send a request containing own device MAC information to the device to become a partner frame; if the device MAC in the temporary MAC list also exists in the buddy list, resetting the confirmed alive field corresponding to the device MAC in the buddy list, for example, setting the initial value of the confirmed alive field to 6, and after resetting, setting the confirmed alive field to 6; if the device MAC in the buddy list does not exist in the temporary MAC list, subtracting 1 from the confirmed survival field corresponding to the device MAC in the buddy list;
the temporary MAC list of each router is used for storing the equipment MAC of the router, which is received by the router and is used for searching for the partner frame;
step a3, the base station router receives the request from other router as a buddy frame, and determines whether other router exists in its buddy list? If not, sending an identity authentication request frame to other routers, carrying out identity authentication on the base station router by the other routers, returning the identity authentication frame to the base station router after the identity authentication is successful, and continuing the next step; if yes, the process is ended;
in step a3, the request for the buddy frame needs to be retransmitted to ensure the reliability as much as possible, so its bit7 is set to 1, the retransmission timer starts counting from zero, and every retransmission time interval is set with 100 Beacon interval intervals as the basic unit. If the router sending the request to become the partner frame does not receive the request identity authentication frame within the set threshold, the router is considered to be unable to add the partner. The request identity authentication frame also needs to start a retransmission mechanism, the information data element field of the request identity authentication frame is filled with the first 8 bits after the MAC address MD5 of the router for verification by the other party, bit6 is set to 1, which indicates that the request of the router of the other party is received and becomes a partner frame, and if the identity authentication frame is not received before the retransmission duration exceeds the threshold value, the partner join request operation is considered to be failed. The identity authentication frame is the response of the partner router to the request identity authentication frame, the partner router waits for receiving the request identity authentication frame returned by the target router after sending the request to the target router to become the partner frame, if the request identity authentication frame is received and verified successfully, the identity authentication frame is sent, the information element data segment of the identity authentication frame is similar to the request identity authentication frame, and the filled information element data segment is the first 8 bits behind the MAC address MD5 of the router;
step A4, the base station router adds other routers sending the identity authentication frame into the own buddy list, and returns the buddy confirming success/failure frame to other routers, when other routers receive the buddy confirming success frame, the base station router is also added into the own buddy list.
The partner confirms that the success/failure frame is the response of the partner router to the identity authentication frame, and the partner router waits for receiving the identity authentication frame returned by the target router after sending the request identity authentication frame to the target router. And after receiving the identity authentication frame of the opposite party, carrying out identity authentication on the opposite party, if the authentication fails, not adding the partner table, and sending a partner confirmation failure frame, wherein bit6 is set to be 0, if the authentication succeeds, the target router is added into the partner table, and the partner confirmation success frame is sent, wherein bit6 is set to be 1. And the partner confirms that the MAC address of the service area terminal which starts to carry daily operation and the current RSSI value in the successful frame do not need to retransmit information, so bit7 is 0.
2. The invention also includes the following steps that the partner confirms and eliminates, namely when the router monitors that the confirmed survival field of one equipment MAC in the self partner table is 0:
the router sends whether a partner exists a frame to a partner router with a confirmed survival field of 0, judges whether the confirmed existence frame returned by the partner router is received, if not, eliminates the partner router from a partner table of the router, and reports the state information of the partner router to an upper layer.
Whether a partner exists a frame is a request sent to confirm whether a partner still exists when the partner router considers that a partner is lost; the partner router feeds back a confirmation presence frame if the confirmation still exists.
Recognizing whether a partner exists or not, that is, recognizing that a partner does not receive a confirmation message in one interaction cycle, the partner is considered to be absent, and since the wireless environment is more complicated than that of a wired network, the number of times that a router transmits a partner-existence frame or not after receiving a response of the partner router to finding the partner frame last time can be recorded by a confirmation survival field of the partner router in a partner table.
3. The terminal enters the service area, that is, when a terminal enters the service area and is not connected with a router, each router in the service area maintains a state table to be connected respectively, and the state table is used for storing all terminals and the optimal connectable routers in the service area. Thus, when a terminal enters the service area and is not connected with the router, the method further comprises the following steps:
a terminal entering a service area sends out a PROBE frame to the periphery, a router receiving the PROBE frame acquires the current distance value between the terminal and the router, then informs all partner routers in a partner table of the router, records the distance value between the terminal and the partner router sent by the partner router, selects a minimum distance value from the distance values, and adds the router corresponding to the minimum distance value into a self state table to be connected as the optimal connectable router of the terminal.
4. The terminal connects to the service area WIFI, that is, when the terminal selects one router in the service area for connection, as shown in fig. 2, the present invention further includes:
step B1, after the router selected by the terminal completes the connection process with the terminal, it reads its own to-be-connected state table and determines whether the optimal connectable router of the terminal in the to-be-connected state table is itself? If not, sending a request frame of the replacement base station to the optimal connectable router corresponding to the terminal, and continuing the next step; if yes, the process is ended;
considering the situations of load balance among partners and terminal roaming among the partners, when a certain router is overloaded or the signal strength of a certain terminal is weak, sending a request frame of a replacement base station to the partner router, and writing the information of 1 or more terminals into an information element data segment;
step B2, the optimal connectable router corresponding to the terminal checks whether the load of the terminal reaches the load threshold? If yes, the process is ended; if not, returning a replacement base station confirmation frame to the selected router, and continuing the next step;
the replacement base station confirmation frame is a response of the partner router to the replacement base station request frame, and the information element data segment of the replacement base station confirmation frame comprises a terminal which can be served by the partner router and the self load condition;
step B3, the selected router determines whether receiving the alternative base station acknowledgement frame returned by the best connectable router? If so, returning a replacement base station feedback frame to the optimal connectable router, and kicking out the terminal, so that the terminal is roamed to the optimal connectable router; if not, the connection between the terminal and the terminal is maintained, and the process of replacing the base station is stopped.
The replacement base station feedback frame is a feedback message after the router sending the replacement base station request frame receives the replacement base station confirmation frame, and the information element data field of the replacement base station feedback frame comprises the MAC of each optimal partner router corresponding to the terminal kicked out by the router.
5. Load balancing, that is, when the router monitors that its own load reaches the load threshold, as shown in fig. 3, the load balancing further includes:
step C1, the router sends the request frame of the alternative base station to the partner router in the partner table, and then closes the PROBE frame, thereby preventing the terminal from joining;
step C2, the partner router capable of receiving the terminal returns the replacement base station confirmation frame to the router;
step C3, after receiving the base station confirmation frame returned by the partner router, the router screens the terminal which can be rejected from the terminal selection table of the router, then returns a replacement base station feedback frame to the partner router, simultaneously rejects the terminal which can be rejected from the terminal selection table of the router, and interrupts the connection of the rejected terminal at the wireless side;
and step C4, the router opens the Probe frame again to allow the terminal to access when the self load drops to another threshold.
6. The router network disconnection, when the router monitors that it is disconnected, as shown in fig. 4, further includes:
d1, the router sends the frame that the network can not be connected to other partner routers through the driving layer, and relays to the nearest partner router through the relay mode to maintain the user connection;
