ENERGY-SAVING COMMUNICATION METHOD IN WIRELESS SENSOR NETWORKS

摘要

PURPOSE: An energy saving communication method in a wireless sensor network is provided to save energy by applying optimal transmission voltages to a node by deducting the optimal transmission voltages. CONSTITUTION: A node B transmits synchronization packets in a synchronization process by using maximum voltages. The node B confirms the RSSI(Received Signal Strength Indicator) of a reception unit and an LQI(Link Quality Indicator). The node B applies the power reduction recommendation value of a node A to transmission voltages. The node B establishes previous transmission voltages as optimal voltages.
