Abstract

A method of transmitting and receiving data for a wireless sensor network system is disclosed. Transmission and reception intervals for a small amount of data and for a large amount of data are set. A sensor node checks data requested to be transmitted. If the data is a small amount of data, the sensor node transmits the data to a higher or lower communication node during the transmission interval for a small amount of data. If the data is a large amount of data, the sensor node divides the large amount of data and then transmitting resulting data to the higher or lower communication node during the transmission interval for a large amount of data. The sensor node receives the small amount of data during the reception interval for a small amount of data and the large amount of data during the reception interval for a large amount of data.

Claims

1. A method of transmitting and receiving data for a wireless sensor network system, the method comprising:

setting transmission and reception intervals for a small amount of data and transmission and reception intervals for a large amount of data so that the intervals correspond to a hierarchical structure for a plurality of sensor nodes which constitutes the wireless sensor network system;

each of the sensor nodes checking whether data requested to be transmitted is a small amount of data or a large amount of data;

if the data requested to be transmitted is a small amount of data, the sensor node transmitting the small amount of data to a higher or lower communication node during the transmission interval for a small amount of data;

if the data requested to be transmitted is a large amount of data, the sensor node dividing the large amount of data and then transmitting resulting data to the higher or lower communication node during the transmission interval for a large amount of data; and

the sensor node receiving the small amount of data during the reception interval for a small amount of data and the large amount of data during the reception interval for a large amount of data.

2. The method according to claim 1, wherein, if an amount of the data requested to be transmitted is larger than a capacity of a transmission buffer of a communication module, the sensor node determines that the data is the large amount of data.

3. The method according to claim 1, wherein the sensor node has the transmission and reception intervals for a large amount of data which is set such that they are included within a sleeping interval.

5. The sensor node according to claim 3, wherein, if an amount of the data requested to be transmitted is larger than a capacity of a transmission buffer of the communication module, the control unit determines that the data is the large amount of data.

6. The sensor node according to claim 3, wherein the transmission and reception intervals for a large amount of data are set such that they are included within a sleeping interval.

4. A sensor node for a wireless sensor network system, comprising:

a communication module for taking charge of communication with a higher or lower communication node; and

a control unit for;

receiving set information corresponding to a hierarchical structure of a plurality of sensor nodes which constitutes the wireless sensor network system, and setting transmission and reception intervals for a small amount of data and transmission and reception intervals for a large amount of data,

checking whether data requested to be transmitted is a small amount of data or a large amount of data,

if the data requested to be transmitted is a small amount of data, transmitting the small amount of data to the higher or lower communication node during the transmission interval for a small amount of data,

if the data requested to be transmitted is a large amount of data, dividing the large amount of data and then sequentially transmitting resulting data to the higher or lower communication node during the transmission interval for a large amount of data, and

receiving the small amount of data during the reception interval for a small amount of data and the large amount of data during the reception interval for a large amount of data from the higher or lower communication node.
