A header compression and packet delivery method in a sensor network and a device therefor are provided to enable a node which transmits data to transmit the data in a type suitable for a sensor node which receives the data, thereby efficiently delivering a packet. An inquiry message transmitter(210) transmits an inquiry message which inquires about whether a sensor node within a sensor network supports an adaptation layer function, to the sensor node. A reply message receiver(220) receives a reply message for the inquiry message. A decider(230) analyzes the reply message to decide whether the sensor node supports the adaptation layer function. If so, a header compressor(240) compresses an IP(Internet Protocol) header within a packet, and makes the IP header intact if the adaptation layer function is not supported. A packet transmitter(250) transmits the packet to the sensor node. |
