Conclusions an indoor environment, a user’s location is situated applying mobile commuGenerally, in6. Conclusionsnication technologies for instance Wi-Fi, Bluetooth, and UWB. Nonetheless, ais located using mobil Normally, in an indoor environment, a user’s location positioning error occurs in an indoor atmosphere due toWi-Fi, Bluetooth, and UWB. However, a position munication technologies like a propagation loss problem as a result of numerous walls and obstacles. Within this paper, we proposed a positioning system based around the modified PSO rorimprove the an indoor error. The proposed scheme innovatively establishes the initial to occurs in positioning atmosphere due to a propagation loss dilemma because o walls and obstacles. In this paper, we proposed asearch region in the PSObased on the search area from the classic PSO. Limiting the initial positioning strategy assists the PSO to enhance the positioning error.

In the future, we plan to study the positioning trouble.
