METHOD FOR INCREASING ENERGY EFFICIENCY IN PREDICTION-BASED TARGET TRACKING SENSOR NETWORK

摘要

PURPOSE: An energy efficiency increasing method efficiency in a target object tracking sensor network based a prediction is provided to supply in order to reduce an overhead generated due to a history exchange between a sink node and sensor nodes in a sensor network. CONSTITUTION: A transmission node decides the presence of transmission of a current data(S210). The transmission node predicts a current state of the target based on an old data with indicating an old state of a target(S220). The transmission node compares the predicted data and the current data(S230). The transmission node decides the state of the target whether it has within a predictable error range or not. The transmission node decides the presence of transmission of the current data(S212,S240).
