Abstract
A header compression and packet transmission method in a sensor network and an apparatus therefor, for selecting technologies related to Internet Protocol (IP) header compression according to characteristics of each node, and processing the technologies. The header compression and packet transmission method and apparatus therefor distinguishes a node supporting the adaptation layer function and a node that does not support the adaptation layer function, and determines whether to compress the packet, thereby enabling a node transmitting data to transmit the data having a proper form that is acceptable to a sensor node receiving the data. By doing so, an efficient packet transmission is possible.
Claims25
A header compression and packet transmission method in a sensor network, the method comprising:
- transmitting an inquiry message to a sensor node in the sensor network inquiring whether the sensor node supports an adaptation layer function;
- receiving a reply message transmitted from the sensor node using a function of a lower layer used by the sensor node;
- analyzing the reply message and determining whether the sensor node supports the adaptation layer function according to the analyzed reply message;
- compressing an Internet Protocol (IP) header and transmitting a packet with the compressed IP header to the sensor node when it is determined that the sensor node supports the adaptation layer function;
- and
- transmitting a packet to the sensor node without compressing the IP header when it is determined that the sensor node does not support the adaptation layer function.
A header compression and packet transmission apparatus in a sensor network, the apparatus comprising:
- an inquiry message transmission unit to transmit an inquiry message to a sensor node in the sensor network inquiring whether the sensor node supports an adaptation layer function;
- a reply message reception unit to receive a reply message corresponding to the inquiry message and which is transmitted from the sensor node by using a function of a lower layer used by the sensor node;
- a determination unit to analyze the received reply message and to determine whether the sensor node supports the adaptation layer function;
- a header compression unit to compress an Internet Protocol (IP) header in a packet when the determination unit determines that the sensor node supports the adaptation layer function, and does not compress an IP header in a packet when the determination unit determines that the sensor node does not support the adaptation layer function;
- and
- a packet transmission unit to transmit the packet to the sensor node.
A computer readable recording medium having recorded thereon a program to execute a header compression and packet transmission method in a sensor network, the header compression and packet transmission method comprising:
- transmitting an inquiry message to a sensor node in the sensor network inquiring whether the sensor node supports an adaptation layer function;
- receiving a reply message corresponding to the inquiry message transmitted from the sensor node using a function of a lower layer used by the sensor node;
- analyzing the reply message and determining whether the sensor node supports the adaptation layer function according to the analyzed reply message;
- compressing an IP (Internet Protocol) header and transmitting a packet with the compressed IP header to the sensor node when it is determined that the sensor node supports the adaptation layer function;
- and
- transmitting a packet to the sensor node without compressing the IP header when it is determined that the sensor node does not support the adaptation layer function.
A mobile device in a sensor network, including a header compression and packet transmission apparatus, the apparatus comprising:
- an inquiry message transmission unit to transmit an inquiry message to another sensor node in the network to determine whether the sensor node supports an adaptation layer function;
- a header compression unit to selectively compress at least a portion of a packet when the sensor node is determined to support the adaptation layer function;
- and
- a packet transmission unit to transmit the packet to the sensor node;
- wherein the packet includes the compressed portion if the sensor node supports the adaptation layer function, and includes an uncompressed portion if the sensor node does not support the adaptation layer function.
A method of compressing data and communicating with a sensor node in a sensor network, the method comprising:
- receiving a message inquiring whether the sensor node supports an adaptation layer function;
- transmitting a reply message indicating whether the sensor node supports an adaptation layer function;
- and
- receiving a data packet based on the content of the reply message, the data packet including at least one compressed portion if the sensor node supports an adaptation layer function.
A device in a sensor network, the device comprising:
- an inquiry message reception unit to receive an inquiry message inquiring whether the mobile device supports an adaptation layer function;
- a reply message transmission unit to transmit a reply message indicated whether the sensor node supports the adaptation layer function;
- and
- a packet reception unit to receive a packet based on the reply message, the data packet including at least one compressed portion if the mobile device supports the adaptation layer function.
