Abstract

In this paper, two kinds of interrogator selection schemes named as random interrogator selection and hybrid interrogator selection methods are considered to enhance the positioning accuracy under indoor wireless LAN environments and the performances are compared with those of the conventional methods called as normal and reference interrogator selection schemes. These interrogator selection schemes are based on received signal strength(RSS) levels and trilateration method. A testbed was set up to measure and compare the positioning estimation error of the considered methods and previous conventional ones. The experiments results showed that the accuracy of location estimation was enormously improved with the hybrid method as much as 3m especially in a hostile environment with some obstacles. Meanwhile, the differences of estimation errors are not so much (< 0.2m) without obstacle conditions among the four kinds of interrogator selection methods.
