Abstract

A proxying process method for traffic of a wireless node and a system using the method are provided. The proxying process method includes: maintaining a virtual node which stores a communication packet from a server, destined for a first node; and transmitting the stored communication packet from the virtual node to a second node when a transmission request for the communication packet is transmitted to the first node by the second node.

Claims

1. A proxying process method for traffic of a wireless node, the method comprising:

maintaining a virtual node which stores a communication packet from a server, destined for a first node; and

transmitting the stored communication packet from the virtual node to a second node when a transmission request for the stored communication packet is transmitted to the first node by the second node.

2. The proxying process method of claim 1, wherein the transmitting of the stored communication packet from the virtual node to the second node comprises:

suspending the transmitting of the communication packet to the second node, the communication packet being stored in the first node; and

transmitting the communication packet to the second node when the transmitting of the communication packet is suspended on the first node.

3. The proxying process method of claim 2, wherein the suspending of the transmitting of the communication packet to the second node prevents retransmission of the communication packet by the first node.

4. The proxying process method of claim 1, further comprising:

receiving a query associated with a proxying process from the first node; and

determining whether a service with respect to the proxying process is possible in response to the received query.

5. The proxying process method of claim 4, wherein the determination of whether the service with respect to the proxying process is possible comprises:

registering a parameter associated with the first node when the proxying process is possible as a result of the determination, thereby generating the virtual node corresponding to the first node.

6. The proxying process method of claim 1, further comprising:

converting the transmitted communication packet according to a wireless protocol to transmit the converted communication packet to the first node when the server communicates with the virtual node via a wire.

7. The proxying process method of claim 1, further comprising:

the communication packet bypassing the virtual node so that the bypassed communication packet is transmitted directly to the first node when the server wirelessly communicates with the virtual node.

8. The proxying process method of claim 1, wherein the virtual node is an access point (AP) or a base station (BS).

9. A computer-readable storage medium storing a program for implementing a proxying process method, the method comprising:

maintaining a virtual node which stores a communication packet from a server, destined for a first node; and

transmitting the stored communication packet from the virtual node to a second node when a transmission request for the communication packet is transmitted to the first node by the second node.

10. A proxying process system for traffic of a wireless node, the system comprising:

a virtual node generation unit generating a virtual node which stores a communication packet from a server, destined for a first node; and

a packet transmission unit transmitting the stored communication packet from the virtual node to a second node when a transmission request for the communication packet is transmitted to the first node by the second node.

11. The proxying process system of claim 10, wherein the packet transmission unit

suspends the transmitting of the communication packet to the second node, the communication packet being stored in the first node;

and

transmits the communication packet to the second node when the transmitting of the communication packet is suspended on the first node.

12. The proxying process system of claim 10, wherein the packet transmission unit prevents retransmission of the communication packet by the first node to suspend the transmitting of the communication packet to the second node.

13. The proxying process system of claim 10, further comprising:

a query receiving unit receiving a query associated with a proxying process from the first node; and

a determination unit determining whether a service with respect to the proxying process is possible in response to the received query.

14. The proxying process system of claim 10, further comprising:

a parameter registration unit registering a parameter associated with the first node when the proxying process is possible as a result of the determination,

wherein the virtual node generation unit generates the virtual node corresponding to the first node.

15. The proxying process system of claim 10, wherein the packet transmission process unit, when the server communicates with the virtual node via a wire, converts the transmitted communication packet according to a wireless protocol to transmit the converted communication packet to the first node.

16. The proxying process system of claim 10, wherein, in the packet transmission unit, when the server wirelessly communicates with the virtual node, the communication packet bypasses the virtual node so that the bypassed communication packet is transmitted directly to the first node when the server wirelessly communicates with the virtual node.

17. The proxying process system of claim 10, wherein the virtual node is an access point (AP) or a base station (BS).
