FLOODING METHOD FOR REAL-TIME DATA TRANSMISSION IN SENSOR NETWORK

摘要

PURPOSE: A flooding method for a real time data transmission in a sensor network is provided to supply a transmission rate of the real time data to enhance within the time limit. CONSTITUTION: A current node transmits a data into a main receiving node(S130). The current node transmits a copy of the data into a sub-receiving node. The main receiving node decides a channel available whether or not through a carrier sensing(S140). The main receiving is broadcasting an interruption message with informing a transmission interruption of the data in order to throw away the copy of the data owned by the sub-receiving node when the channel use possible(S150). The current node transmits the data through the main receiving node(S160).
