A display substrate includes a plurality of pixel parts, each including a first and second gate lines, a source line, first, second, and third transistors, and a pumping capacitor. The method includes allocating cluster resources for recognizing a location of a mobile node, setting operation of each node by deciding a cluster operation state for the mobile node, measuring distances between the mobile node to each of anchor nodes, and recognizing a location of the mobile node. Instead, the Intrusion Management System tabulates information indirectly related to the attack and dynamically scales the confidence in the attack detection accordingly.
