Item Sensor Placement to Improve the Positioning Performance Based on Angle of Arrival (AOA)(Scientific Research Publishing, 2010-07) Omidali, Behzad; Shirazi, S. S.In this paper, a method for sensor placement to improve the placement quality based on angle of arrival of signal in a specific area is proposed. The installation place of sensors may be constrained with specified boundaries. In this me-thod, the criterion of maximum quality of placement is the Cramer-Rao bound. The generalized pattern search as an effective method is used to maximize error bound of the placement problem by angle of arrival. Better results are ob-tained in comparison with results of genetic algorithm. The derived results are compared from two aspects of run time and result quality.
