determining, if the selected at least one unauthorized equipment can be allocated to the selected at least one sensor, the selected at least one sensor as a sensor to allocate the selected at least one unauthorized equipment.

4. The method of claim 3, further comprising selecting, if the selected at least one unauthorized equipment cannot be allocated to the selected at least one sensor, another of the at least one sensor in which a RSSI value from the at least one unauthorized equipment is next greatest;

and

repeating the method to determine whether the selected at least one unauthorized equipment can be allocated to the selected at least one sensor.

5. The method of claim 3, wherein determining whether the selected at least one unauthorized equipment can be allocated to the selected at least one sensor, comprises:

determining whether the at least one unauthorized equipment using a same channel as that of the selected at least one unauthorized equipment exists among at least one unauthorized equipment previously allocated to the selected at least one sensor;

comparing, if the at least one unauthorized equipment using the same channel as that of the selected at least one unauthorized equipment exists, a number of the at least one unauthorized equipment using the same channel among the previously allocated at least one unauthorized equipment and a number of preset maximum equipment;

determining, if the number of the at least one unauthorized equipment is less than the number of preset maximum equipment, that the selected at least one unauthorized equipment can be allocated to the selected at least one sensor; and

determining, if the number of the at least one unauthorized equipment is the same as the number of the preset maximum equipment, that the selected at least one unauthorized equipment cannot be allocated to the selected at least one sensor.

6. The method of claim 5, further comprising:

determining, if the at least one unauthorized equipment using the same channel as that of the selected at least one unauthorized equipment does not exist, the number of channels allocated to the selected at least one sensor using channel information of the previously allocated at least one unauthorized equipment;

comparing the number of channels allocated to the selected at least one sensor and a number of preset maximum channels;

determining, if the number of channels allocated to the selected at least one sensor is less than the number of preset maximum channels, that the selected at least one unauthorized equipment can be allocated to the selected at least one sensor; and

determining, if the number of channels allocated to the selected at least one sensor is the same as the number of preset maximum channels, that the selected at least one unauthorized equipment cannot be allocated to the selected sensor.

7. The method of claim 3, wherein determining whether the selected at least one unauthorized equipment can be allocated to the selected at least one sensor, comprises:

comparing the number of at least one unauthorized equipment previously allocated to the selected at least one sensor with a number of preset entire unauthorized equipment;

determining, if the number of at least one unauthorized equipment previously allocated to the selected at least one sensor is less than the number of preset entire unauthorized equipment, that the selected at least one unauthorized equipment can be allocated to the selected at least one sensor; and

determining, if the number of at least one unauthorized equipment previously allocated to the selected at least one sensor is the same as the number of preset entire unauthorized equipment, that the selected at least one unauthorized equipment cannot be allocated to the selected at least one sensor.

8. The method of claim 1, wherein receiving the report comprises:

receiving information of at least one detected equipment from the at least one sensor; and

determining whether the at least one detected equipment is an unauthorized equipment based on information of the at least one detected equipment.

9. A server, comprising:

an unauthorized equipment identity unit configured to determine at least one unauthorized equipment detected by at least one sensor; and

an unauthorized equipment allocation unit configured to determine the at least one sensor to allocate to each of the detected at least one unauthorized equipment based on at least one of a number of channels and a number of at least one unauthorized equipment allocated to each of the at least one sensors and that requests access blocking of the at least one unauthorized equipment allocated to a corresponding sensor to the determined at least one sensor.

10. The server of claim 9, wherein the unauthorized equipment allocation unit is further configured to determine a number of at least one sensor having detected each of the detected at least one unauthorized equipment, align the detected at least one unauthorized equipment in order in which the number of the detection at least one sensors is from least to greatest, select the at least one unauthorized equipment in aligned order, and determine the at least one sensor to allocate the selected at least one unauthorized equipment.

11. The server of claim 10, wherein the unauthorized equipment allocation unit is further configured to select a sensor in which a Received Signal Strength Indication (RSSI) value from the selected at least one unauthorized equipment is greatest among the at least one sensors having detected the selected at least one unauthorized equipment, determine whether the selected at least one unauthorized equipment can be allocated to the selected at least one sensor based on at least one of a number of channels and a number of at least one unauthorized equipment previously allocated to the selected at least one sensor, and determine, if the selected at least one unauthorized equipment can be allocated to the selected at least one sensor, the selected at least one sensor as the at least one sensor to allocate the selected at least one unauthorized equipment.

12. The server of claim 11, wherein the unauthorized equipment allocation unit is further configured to exclude the selected at least one sensor among the at least one sensor, having detected the selected at least one unauthorized equipment and select another at least one sensor in which the RSSI value from the at least one unauthorized equipment is greatest, if the selected at least one unauthorized equipment cannot be allocated to the selected at least one sensor, and determine whether the selected at least one unauthorized equipment can be allocated to the selected another at least one sensor.
