Apparatus for transmitting data packets between wireless sensor networks over internet, wireless sensor network domain name server, and data packet transmission method using the same
First Claim
1. An apparatus for transmitting data packets between wireless sensor networks over the Internet, comprising:
- a radio frequency (RF) interface;
an Ethernet interface; and
a network processor connected between the RF interface and the Ethernet interface for converting an input/output data packet between a wireless sensor network and the Internet and sending the converted data packet through a corresponding interface, wherein a desired data packet is sent over the Internet using an Internet communication tunnel.

Abstract
Provided are an apparatus for transmitting data packets between wireless sensor networks over the Internet, a wireless sensor network domain name server, and a data packet transmission method using the same. The data packet transmission apparatus includes: a radio frequency (RF) interface; an ethernet interface; and a network processor connected between the RF interface and the ethernet interface for converting a data packet input/output between a wireless sensor network and the Internet and sending the converted data packet through a corresponding interface. By sending a desired data packet using an Internet communication tunnel over the Internet, the data packet transmission apparatus, wireless sensor network domain name server, and data packet transmission method allow a user to access a wireless sensor network over the Internet anytime and anywhere, interwork directly with the Internet rather than through another server, and perform remote monitoring and control operations.

11. A wireless sensor network domain name server, comprising:
-
a first database for storing and managing region names of a plurality of wireless sensor networks; and
a second database for storing and managing an IP address of each data packet transmission apparatus connecting each of the wireless sensor networks to the Internet, wherein a region name of each of the wireless sensor networks is translated into an Internet protocol (IP) address of a connectable data packet transmission apparatus with reference to the first and the second databases.

12. A method for transmitting data packets between wireless sensor networks over the Internet, comprising:
-
(a) requesting, at a node X included in a source wireless sensor network, binding information of a destination transmission apparatus for connecting to a node Y included in a destination wireless sensor network, to a source transmission apparatus;
(b) sending, at the source transmission apparatus, a query message for obtaining the requested binding information to a wireless sensor network domain name server separately disposed on the Internet, and receiving information about the destination transmission apparatus;
(c) sending, at the source transmission apparatus, a binding request message for configuring an Internet communication tunnel to the destination transmission apparatus; and
(d) checking, at the destination transmission apparatus, a connection state of the node Y, receiving an active message when the node Y is in an active-state, sending a response message in response to the binding request message to the node X through the source transmission apparatus, and configuring the Internet communication tunnel. - View Dependent Claims (13, 14, 15, 16, 17, 18)
