چکیده

امروزه با گسترش اینترنت یکی از چالش‌های بزرگ شبکه‌های ارتباطی سرعت دسترسی به آن است. در هنگامی که دستگاه‌های مختلفی به شبکه بی‌سیم متصل می‌شوند سرعت دسترسی به یک چالش تبدیل می‌شود. شبکه‌های وای‌فای با مشکلاتی روبه‌رو هستند از جمله اینکه استفاده از آن‌ها در برخی مکان‌ها دشوار و یا غیر ممکن بوده و سرعت آن برای پاسخگویی به نیازهای امروزی کند است. در این مقاله ضمن معرفی لای‌فای، ویژگی‌ها و محدودیت‌های این شبکه که داده‌ها در آن از طریق نور مرئی به‌صورت بی‌سیم تبادل می‌شوند، بررسی شده است. یکی از مواردی که برای این شبکه نوین اهمیت دارد، طرز کار آن و روابط علمی و مدل‌های ریاضی تعریف شده برای آن است که در این پژوهش به آن و همچنین معماری لای‌فای پرداخته شده است. کاربردها و ایده‌های نوینی برای لای‌فای وجود دارد که در این مقاله بررسی شده‌اند. در پایان عملکرد لای‌فای مورد ارزیابی قرار گرفته شده است. این ارزیابی شامل تحلیل امنیتی و بررسی مزایا و معایب فناوری ارتباطی لای‌فای نسبت به وای‌فای است.

چکیده [English]

Nowadays, with the widespread use of the Internet, one of the great challenges of communication networks is the access speed. The speed of access becomes a challenge when different devices connect to a wireless network. Wi-Fi networks are facing some problems, such as difficult or impossible connectivity in some places and a speed far below today's needs. In this research, while introducing Li-Fi technology, where the data is exchanged wirelessly through visible light, its features and limitations are studied. The architecture and scientific relations and mathematical models of this new technology are also presented. There are new ideas and applications for the Li-Fi that are explored in this paper and finally, Li-Fi technology is compared to Wi-Fi technology based on various parameters.
