Patent ID: 8086433

Claim:
A simulation apparatus for a sensor network comprising: a space database storing space information; a database storing standard specifications of sensors or sensor nodes; and a modeling unit extracting, from the space database, information on a 3-dimensional (3D) virtual space in which a sensor or a sensor node is positioned, obtaining characteristics of the sensor, including a sensing coverage, and characteristics of the sensor node, including a quantity of energy consumption and a radio wave traveling distance, based on the standard specifications, and virtually operating the sensor or the sensor node according to a preset schedule that includes a data acquisition cycle and a report cycle to obtain a current state of the sensor or the sensor node including remaining battery power, wherein the radio wave traveling distance is one of the characteristics of the sensor node determined with respect to surrounding topography and facilities information, and a quantity of battery consumption of the sensor node is determined according to the radio wave traveling distance of the sensor node.
