SENSOR NETWORK USING ADAPTIVE THRESHOLD AND A CONTROL METHOD USING THEREOF, CAPABLE OF ADAPTIVELY APPLYING THE SENSOR NETWORK ACCORDING TO THE SITUATION OF THE SENSOR NETWORK

摘要

PURPOSE: A sensor network using adaptive threshold and a control method using thereof are provided to reduce the energy consumption for the verification of the event report and transmission by creating the event report according to the security boundary value.;CONSTITUTION: A base station broadcasts the division information message to a sensor network(S501). The division information message comprises the security boundary value information. Each sensor node checks the hop count between itself and the base station(S502). Each sensor node compares the hop count within the hop count and division information message(S503). Each sensor node confirms the security boundary value from the division information message(S504). The security boundary value comes under the domain where itself belongs. The fixed initial security boundary value is updated to the security boundary value(S505).;COPYRIGHT KIPO 2010
