Abstract: 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).

Abstract: Disclosed herein is a method of establishing the routing path of a sensor network and a sensor node for implementing the method. Each of a plurality of sensors belonging to a sensor network is assigned a key index and a key corresponding to the key index. The sensor node acquires information about key indices possessed by sensor nodes existing on a candidate routing path. The sensor node selects a final routing path from among a plurality of candidate routing paths using the information about the key indices. Accordingly, the present invention can implement a sensor network having improved security.

Abstract: PURPOSE: A routing path selection method for improving the detection power of statistical filtering and a sensor node for implementing the same are provided to select a transferring route having strong security intensity by evaluating the transferring route based on the key information held by the sensor node. CONSTITUTION: A security intensity function operator(120) calculates the security intensity function value by using the key index information which is not held by a sensor node. According to each sensor node which transfers manipulative messages, a manipulative message processor(130) generates routing candidate path tables including the security intensity function value information. Among the plural rouging candidate routes included in the routing candidate route tables, a routing path selector(150) selects as the final routing route the route having the minimum security function value.

Abstract: PURPOSE: A path renewal method in a filtering based wireless sensor network is provided to reduce power consumption of a sensor node by maintaining protection ability against a false report and transferring data through a well-balanced route. CONSTITUTION: A route of a node is established through a PSM(Path Setting Method) in a wireless sensor network(S1). A reference node is searched along the established route(S2). The residual energy of the reference node is smaller than the reference threshold value. The route of a target node is reestablished among the lower nodes of the reference nodes(S3). The data transfer quantity of the target node is higher than other lower nodes of the reference nodes.
