DATA BROADCASTING AND FEEDBACK METHOD IN SENSOR NODE

摘要

PURPOSE: Data broadcasting performed in a sensor node and a feedback method thereof are provided to prevent power consumption or collision of feedback data, and to extend a lifespan of network by effectively reducing the number of unnecessary feedback. CONSTITUTION: An error is made in receiving of data broadcasted to neighboring nodes of a receiving node. An acknowledgement response frame is transmitted to transmitting nodes within a constant time. The broadcasted data is normally received. After the predetermined time, an affirmation receiving response frame is transmitted to the transmitting node.
