Abstract:

Abstract This paper presents a method of search for the optimal antenna deployment for use in spatial localization systems based on the radio frequency identification technology (RFID). It involves minimizing the average error of a combinational localization method consisted of a trilateration algorithm, fingerprinting algorithm, and an intersectional algorithm. During the computational experiment we found the optimal solution among several antenna deployment patterns for a square localization field. The solution is a grid pattern with antenna interrogation zones oriented towards the field center. References Wang C. S.
