A wireless network device and a communication method using the wireless network device are provided to simplify an association process of the device moving over different wireless networks and to enhance mobility of the device. The wireless network device includes an allocater allocating a device identifier (ID) to a predetermined device, an information generator generating information on the allocated device ID, and a first controller generating a packet containing the generated device ID and transmitting the generated packet to another wireless network.

What is claimed is: 1. A wireless network device of a first wireless network, the wireless network device comprising: an allocater which allocates a device identifier (ID) to a predetermined device; an information generator which generates information on the device ID; and a controller which generates a packet containing the information on the device ID and transmits the packet to a second wireless network, wherein the first and second wireless networks are independent coordinator-based networks, and wherein, in the second wireless network, the device ID is allocated to the predetermined device. 2. The wireless network device of claim 1, wherein the information on the device ID comprises at least one of an allocated device ID, a Medium Access Control (MAC) address, and a sequence number. 3. The wireless network device of claim 2, wherein the allocater allocates the device ID if the predetermined device has associated with or dissociated from the wireless network device. 4. The wireless network device of claim 1, wherein the first wireless network and the second wireless network are both ad-hoc networks. 5. A wireless network device of a first wireless network, the wireless network device comprising: a packet receiver which receives a packet from a second wireless network containing device identifier (ID) information of a predetermined device; an information extractor which extracts the device ID information from the packet; and a controller which determines a device ID to be allocated to the predetermined device of the first wireless network according to the device ID information, wherein the first and second wireless networks are independent coordinator-based networks, and wherein, in the first wireless network, the device ID is allocated to the predetermined device. 6. The wireless network device of claim 5, wherein the device ID information comprises at least one of an allocated device ID, a Medium Access Control (MAC) address, and a sequence number. 7. The wireless network device of claim 6, wherein the device ID information comprises a device ID previously allocated to the predetermined device in the second wireless network. 8. The wireless network device of claim 7, wherein the controller determines the device ID previously allocated in the second wireless network based on the extracted device ID information, selects a device ID that is not duplicated with the determined device ID among allocatable device IDs, and allocates the selected device ID to a newly associated device. 9. A communication method using a wireless network system, the communication method comprising: a first wireless network allocating a device identifier (ID) to a predetermined device; the first wireless network generating information on the device ID; and the first wireless network generating a packet containing the information on the device ID and transmitting the packet to a second wireless network, wherein the first and second wireless networks are independent coordinator-based networks, and wherein, in the second wireless network, the device ID is allocated to the predetermined device. 10. The communication method claim 9, wherein the information on the device ID comprises at least one of an allocated device ID, a Medium Access Control (MAC) address, and a sequence number. 11. The communication method of claim 10, wherein the device ID is allocated if the predetermined device has associated with or dissociated from the wireless network device. 12. The communication method of claim 9, wherein the first wireless network and the second wireless network are both ad-hoc networks. 13. A communication method using a wireless network system, the communication method comprising: a first wireless network receiving a packet from a second wireless network containing a device identifier (ID); the first wireless network extracting device ID information from the packet; and the first wireless network determining a device ID to be allocated to a device of the first wireless network according to the device ID information, wherein the first and second wireless networks are independent coordinator-based networks. 14. The communication method of claim 13, wherein the extracted device ID comprises at least one of an allocated device ID, a Medium Access Control (MAC) address, and a sequence number. 15. The communication method of claim 14, wherein the device ID information comprises a device ID previously allocated to the device in the second wireless network. 16. The communication method of claim 15, wherein the allocating of the device ID comprises: determining the device ID previously allocated in the second wireless network based on the extracted device ID information to select a device ID that is not duplicated with the determined device ID among allocatable device IDs; and allocating the selected device ID to a newly associated device.
