COMMUNICATION METHOD OF COMMUNICATION APPARATUS

摘要

PURPOSE: A communication method of a communication device is provided to efficiently transmit data by using a limited wireless sensor network resource. CONSTITUTION: First variations of data values in a first transmission section are measured according to unit time (S102). An average of the first variations is calculated (S104). A filter value is calculated based on the average value (S110). Each data is filtered in a second transmission section by using the filter value to be transmitted (S200). If the average value is bigger than a first reference value, a dynamic mode is executed in the second transmission section. If the average value is smaller than or same as the first reference value, a static mode is executed in the second transmission section.
