BibTeX does not have the right entry for preprints. This is a hack for producing the correct reference:
@booklet{EasyChair:9558,
author = {Ghassan Samara and Hussam Abu Munshar and Ruzayn Quaddoura},
title = {Using Security Centre in Indoor Internet of Things},
howpublished = {EasyChair Preprint 9558},
year = {EasyChair, 2023}}
