1 to 5, a network system according to an embodiment of the present invention includes a plurality of second devices 200.

Each of the second devices 200 may be connected to the first device 100 through a network.

The first device 100, which is a sender, may simultaneously transmit a discovery message for searching to each second device 200 as a receiver.

The network may be a mobile Internet such as wireless Internet such as WiFi (Wireless Fidelity), Wireless Broadband Internet (WiBro) or World Interoperability for Microwave Access (WiMax), Global System for Mobile communication (GSM) 3G mobile communication network such as WCDMA or CDMA2000, 3.5G mobile communication network such as High Speed Downlink Packet Access (HSDPA) or HSUPA (High Speed Uplink Packet Access), LTE (Long Term 4G mobile communication network such as Evolution network or LTE-Advanced network, and 5G mobile communication network, but the present invention is not limited thereto.

The first device 100 may include a first receiving unit 110 and a first transmitting unit 120.

The first transmitting unit 120 may be connected to each of the second devices 200 and may transmit data to each of the second devices 200. The first receiving unit 110 may transmit data to the second devices 200 To receive data from each of the second devices 200

The first device 100 may be connected to the first receiving unit 110 and the first transmitting unit 120 to control the first receiving unit 110 and the first transmitting unit 120 And may further include a first control unit 130. In one example, the first device 100 may include a mobile device. The mobile device may include a smart phone capable of storing and executing an application.

The plurality of second devices 200 may include a first device A, a second device B, a third device C, and a fourth device C, for example. The first to fourth devices may include an electrical product.

For example, the first device (Device A) may be a robot cleaner, the second device (Device B) may be a television, the third device (Device C) C) may be an air conditioner. Of course, the type of such electrical appliance is only one example, and not limited thereto. As another example, the electric appliance may include a refrigerator, a cooking appliance, a water purifier, a drier or a dishwasher.

Each of the second devices 200 may include a second receiving unit 211 or 221, a second controlling unit 212 or 222 or a second transmitting unit 213 or 223

The second receiving units 211 and 221 may receive data from the first device 100. [

In more detail, the second receiving units 211 and 221 may receive a discovery message from the first transmitting unit 120. [

That is, the first device receiving unit 211, which is the second receiving unit 211 or 221 of the first device (Device A), and the second receiving unit 211 or 221 of the second device (Device B) 2 device receiving unit 221 can receive a discovery message from the first transmitting unit 120, respectively.

The discovery message received by the second receiving unit 211 or 221 from the first transmitting unit 120 may be a packet 10 including priority information.

Here, the priority information means information related to the data transmission order of each second device 200 when each of the second devices 200 transmits data to the first device 100.

The priority information may be included in the header 10a of the packet 10.

By arranging the priority information in the header 10a of the packet 10, each of the second devices 200 can quickly extract the priority information from the packet 10. [

The second control unit 212 or 222 may include a first device control unit 212 included in the first device A and a second device control unit 222 included in the second device B .

The second transfer units 213 and 223 are connected to the first device transfer unit 213 included in the first device A and the second device transfer unit 223 included in the second device B, . ≪ / RTI >

Each of the second devices 200 may be provided with a unique identifier. The unique identifier may be stored in the device storage units 214 and 224 of each second device 200.

For example, a first identifier may be assigned to the first device storage unit 214, and a second identifier may be assigned to the second device storage unit 224.

The second controllers 212 and 222 may extract the priority information included in the packet 10 and calculate a delay time based on the priority information.

Here, the delay time refers to a time until a second time point at which the second transmission unit 213 or 223 transmits a response message to the first reception unit 110 based on the set first time point.

That is, the second controllers 212 and 222 can calculate different delay times according to the priorities included in the priority information.

Also, the second controllers 212 and 222 can calculate a shorter delay time as the priority is higher.

For example, the first device control unit 212 calculates a first delay time T1, and the second device control unit 222 calculates a second delay time T2 different from the first delay time T1 can do.

Here, the first delay time T1 and the second delay time T2 are different from each other.

If the priority (Priority 1) of the first device (Device A) is earlier than the priority (Priority 1) of the second device (Device B), the first delay time Is shorter than the delay time T2.

The second transmission units 213 and 223 may transmit the response message to the first device 100 based on the delay time.

That is, the second transmitting unit 213 or 223 may transmit the response message including the unique identifier to the first receiving unit 110 immediately after the delay time passes.

More specifically, the first device transmission unit 213 may transmit the response message to the first receiving unit 110 after the first delay time T1, and the second device transmitting unit 223 may transmit the response message to the first receiving unit 110 And may transmit the response message to the first receiver 110 after the second delay time T2.

Accordingly, the second transmitting units 213 and 223 of each second device 200 can sequentially transmit the response message to the receiving unit of the first device 100, respectively.

That is, a response message can be transmitted to the first receiving unit 110 at a different time point of each of the second transmitting units 213 and 223, thereby preventing the concentration of traffic in the first device 100 do.

Hereinafter, a network method according to another embodiment of the present invention will be described with reference to the drawings.

6 is a flowchart of a network method according to another embodiment of the present invention.

Referring to FIG. 6, a network method according to an exemplary embodiment of the present invention includes receiving a packet (S10), extracting priority information (S20), calculating a delay time (S30) To the first device (S40).

In step S10 of receiving the packet, each of the second devices 200 receives a packet 10 including priority information from the first device 100 via a network.

The second receiving units 211 and 221 provided in each of the second devices 200 may receive the packets 10 from the first transmitting unit 120 included in the first device 100. [

Next, in the step S20 of extracting the priority information, the second control units 212 and 222 provided in each second device 200 extract the priority information included in the packet 10 do,

If the second control unit 212 or 222 can not extract the priority information, the network method ends.

Next, the delay time is calculated (S30), and the second control unit (212, 222) can calculate the delay time based on the priority information.

As described above, the second controllers 212 and 222 can calculate the delay time shorter as the priority is higher.

In step S40 of transmitting the response message to the first device, each of the second devices 200 transmits a response message to the first device 100 based on the delay time.
