SENSOR NODE DEPLOYMENT METHOD OF SENSOR NETWORK

Disclosed is a sensor node deployment method for a sensor network. According to embodiments of the present invention, the convenience of use and the utilization of a sensor network system are improved by determining the optimum position of a sensor node by automatically analyzing a system feature element, a human element, and an environmental element affecting a sensor node deployment. The present invention is applied in an unmanned monitoring boundary field about a main facility or a weak monitoring area, which is difficult for a human to approach, by improving the technical reliability of a wireless sensor network by arranging a sensor node in a position with the maximum coverage in a cell.
