The invention is used in the letter routing application scene, solves the problem that the network-gramming device can not be accurately judged in the prior art, and the like, and further describes the technical scheme of the invention by combining the following preferred embodiments of the invention with the accompanying drawings, but the invention is not limited to the embodiments.
Example one
Most of the existing wireless network applications only have one router, and when the terminal equipment is accessed into the router, the router can only judge whether the equipment is a network-rubbing mode through the signal intensity use range of the access equipment.
However, in the application of the primary and secondary routers, a method for judging the network-rubbing equipment by using the primary and secondary routers at the same time does not exist, the secondary router in the primary and secondary router is only used for expanding the network coverage node at present, so that the wireless coverage is wider, and actually, the position and the distance of the network-rubbing equipment are easier to judge due to a plurality of routing nodes in the application of the primary and secondary router, so that the network-rubbing equipment can be effectively prevented by using each routing node.
The embodiment discloses a method for preventing a master-slave route from being stolen from a network aiming at a scene of the master-slave route, as shown in fig. 2, the method comprises the following steps:
s1, receiving signal information between terminal equipment 4 and each routing node 3 respectively;
and S2, judging whether the terminal equipment 4 is a network rubbing equipment or not according to the signal information.
The routing node 3 here includes a parent route 1 and each child route 2 in the network, the number of the child routes 2 may be one, or two or more, and here, whether the terminal device 4 is a network-attach device is determined according to the signal strength of the parent route 1 and each child route 2 to the terminal device 4.
The signal information here includes the MAC address of each routing node 3 and the beacon signal strength of each routing node 3, and the MAC address of each routing node 3 corresponds to the beacon signal strength one to one.
Further, as shown in fig. 3, before step S1, the method further includes:
s0. inquire the terminal equipment 4 about the signal information between the terminal equipment 4 and each routing node 3 according to a set frequency.
When a terminal device 4 is connected to any one of the routing nodes 3, it indicates that it is connected to the network constructed by the child-parent route, and it will receive the beacon signal of the any routing node 3, and may also receive beacon signals sent by other routing nodes 3, and step S0 is used to request to query the signal strength and MAC address of each routing node 3beacon signal received by the terminal device 4 connected to the network.
And, in step S0, the terminal device 4, after receiving the query command, transmits the received signal information to the parent route 1 and/or the child route 2 via the wireless network.
Further, in step S1, the signal information between the terminal device 4 and the routing node 3 is received by the parent route 1 and/or the child route 2.
In this embodiment, the terminal device 4 sends the signal information to the female router 1, the female router 1 receives the signal information returned by the terminal device 4, and the female router 1 determines whether the terminal device 4 is a network gramming device according to the signal information. The terminal device 4 accessing the local network may or may not receive the signal of the parent route 1, but the terminal device 4 is connected to the wireless network through the local network at this time, so that the signal information can be transmitted to the parent route 1 by the wireless network.
It should be noted that: although SSIDs (wireless network names) of the routing nodes 3 of the wireless network built by the child-parent routing are the same, since hardware devices of the routing nodes 3 are different, MAC addresses included in beacon frames sent by the routing nodes 3 are different. Although the terminal device 4 receives the beacon signal of the same SSID, it can recognize which routing node 3 sent the beacon signal, and thus it can be used to count which routing node 3 received the beacon signal by the terminal device 4 and the signal strength of the beacon signal.
Therefore, when returning the received signal strength and the MAC address thereof to the parent router 1, the terminal device 4 can send two pieces of information, namely the MAC address of the received beacon frame and the beacon signal strength, so that the parent router 1 can perform statistics according to the MAC address and the signal strength after receiving the MAC address and the signal strength.
Because the strength of the beacon signal received by the terminal device 4 from each routing node 3 is inversely proportional to the distance between the terminal device 4 and the routing node 3, when the received signal is weaker, the terminal device 4 is farther from the routing node 3 which transmits the beacon signal, and meanwhile, the terminal device 4 receives fewer beacon signals of the routing nodes 3, the terminal device 4 is located at the periphery of the child-mother router 1 network, and the position of the terminal device 4 is also described from another angle.
The parent route 1 may select a period of time to count the signal strength of beacon signals received by the terminal device 4. For example, the parent route 1 continuously counts the situations of beacon signals received by each terminal device 4 within 24 hours, and records the situations in a mode of average signal strength, taking two child routes 2 as an example, the recording results are shown in the following table:
| terminal device | Mother route node | Sub-routing node 1 | Sub-routing node 2 |
| Device 1 | Is not received | -65dbm | Is not received |
| Device 2 | -55dbm | -50dbm | -76dbm |
| … | … | … | … |
| Device n | Is not received | Is not received | -60dbm |
Specifically, as shown in fig. 4, in step S2, it is determined whether the terminal device 4 is a network skimming device by the following method:
s21, judging whether the number of routing nodes 3 capable of receiving beacon signals by the terminal equipment 4 reaches a preset number, if so, executing a step S22, and if not, executing a step S23;
s22, judging whether the signal intensity of at least one routing node is greater than a first preset intensity or not, and if not, judging that the routing node is a network-stealing device;
and S23, judging whether the signal intensity of at least one routing node 3 is greater than a second preset intensity, and if not, judging that the network is a network-rubbing device.
The following is a detailed description of the first preset intensity being-100 db, the preset number being 2, and the second preset intensity being-60 db:
when one terminal device 4 can receive only the beacon signal of one routing node 3 and the signal strength of the beacon signal is-70 db, then step S23 is executed because the number of routing nodes is less than the preset number;
and because the signal intensity of the signal is less than-60 db, the requirement that the signal intensity of at least one routing node 3 is greater than the second preset intensity is not met, so that the terminal device 4 is judged as a network-surfing device, and the data of the terminal device is not processed and forwarded.
When one terminal device 4 can receive beacon signals of two routing nodes 3, and beacon signal strengths of the two beacon signals are-110 db and-120 db, respectively, since the number of routing nodes reaches the preset number, step S22 is executed;
since both signal strengths are less than-100 db, the requirement that the signal strength of at least one routing node 3 is greater than the first preset strength is not satisfied, so that the terminal device 4 is determined as a network-stealing device and still does not process and forward its data. This situation can effectively prevent the network-gramming device that can receive two routing nodes 3 simultaneously from rubbing the network.
When one terminal device 4 can receive beacon signals of two routing nodes 3, and beacon signal strengths of the two beacon signals are-70 db and-110 db, respectively, since the number of routing nodes reaches the preset number, step S22 is executed;
since one of the two signals has a signal strength greater than-100 db, the requirement that the signal strength of at least one routing node 3 is greater than the first preset strength is met, and therefore the terminal device 4 is determined to be a non-network-gramming device.
In addition, the preset number may not be limited to 2, but may be other than 2, preferably a number greater than 1, and when the preset number is 1, the first preset value may be set to a larger number.
Typically, the second predetermined intensity is greater than the first predetermined intensity. The first preset intensity, the second preset intensity and the preset number can be set by a user according to needs or set by a manufacturer when the manufacturer leaves a factory.
In addition, whether the terminal device 4 is a network-surfing device can be judged by the following method:
s211, judging whether the signal intensity in the received signal information is greater than a third preset intensity, if so, judging that the received signal information is a non-network-rubbing device, otherwise, executing a step S22;
and S22, judging whether the number of the routing nodes 3 receiving the signals reaches a routing preset value, if so, judging that the routing nodes are non-network-rubbing equipment, and otherwise, judging that the routing nodes are network-rubbing equipment.
