CHANNEL INTERFERENCE AVOIDANCE METHOD AND SYSTEM THEREOF IN A SINGLE CHANNEL SENSOR NETWORK IN ORDER TO PREVENT AN UNNECESSARY CHANNEL SCAN THROUGH INTERFERENCE PREDICTION

摘要

PURPOSE: A channel interference avoidance method and system thereof in a single channel sensor network are provided to predict interference through the collection of interference information of neighbor nodes.;CONSTITUTION: If an ED(Energy Detection) scan is operated, a specific node calculates WMA(Weighted Moving Average)(403,405). The specific node exchanges the WMA for WMA of a neighbor node(407). A coordinate node recognizes the range of interference through an energy level of the WMA(409). The coordinator node scans the other channel(411).;COPYRIGHT KIPO 2011
