Indoor location-based services have become increasingly vital in various sectors, including industries, healthcare, airports, and crowded infrastructures, facilitating asset tracking and user navigation. This project addresses the critical challenge of optimising beacon placement for indoor location, employing Bluetooth technology as the communication protocol. The significance of this research lies in the effi ciency and accuracy that an optimised beacon layout can provide, enhancing the effectiveness of indoor positioning systems. The algorithm developed takes into con sideration materials attenuation, coverage and Line of Sight (LOS) conditions to optimise its layouts. Experimental validation of the algorithm’s performance was conducted by comparing two beacon layouts: one optimised by the algorithm and the other manually arranged by individuals with empirical knowledge in the field. The experiment considered three distinct positions within the schematic, allowing for a comprehensive assessment of the optimised layout’s superior performance. The results of this research offer insights into the potential of the algorithm to revolu tionise indoor location services, providing a more reliable and cost-effective solution for a multitude of applications.
