چکیده مقاله :
شبکه 4G فعلی برای سلولهای کوچک بی قاعده طراحی نشده بودند. بر اساس سیر تکاملی بلند مدت که وقفه زمان مخابره یک میلی ثانیه و پیشوند تناوبی حدود ۵ میلی ثانیه است این امر باعث شده است. به علاوه رابط درون سلول به مقدار زیادی توسط آرایش طرح‌ریزی شده کنترل شده است.با توسعه سریع فناوریهای بیسیم، مفهوم نسل پنجم سیستمهای ارتباطی مطرح شد؛ که با این پیشرفت هر یک از مشترکان مخابراتی میتوانند با سرعت 1۱هزار گیگابیت در ثانیه به اینترنت متصل شوند. در این بستر، سیستمی که برای پیاده سازی آن مورد استفاده قرار گرفته است، گره هایی که بسته های اطلاعاتی را جا به جا می کنند کاملاً هوشمند هستند و الگوریتم هوشمندسازی گره ها براساس مسیر و مقصد می باشد. این سیستم باعث می شود تا داده ها بسیار هوشمندانه مسیریابی شده و با سرعت و امنیت بالا منتقل شوند در این مقاله سعی شده است تا با اندازه گیری پارامترهای QoS در شبکه های Wimax و 5G به مقایسه آن دو پرداخته و کارایی شبکه های 5G در انتقال داده را مورد بررسی قرار دهیم.
Current 4G networks were not designed for small cells promiscuous. Based on long-term evolution of the transmission time interval of about 5 milliseconds is a cyclic prefix milliseconds and this has caused. Also, a small cell base station (LTE) eNB is highly similar to a large cell eNB mature in functional areas, with the ability to move less. In addition, the interface cell is controlled to a large amount planned by arrangement With the rapid development of wireless technologies, the concept was introduced the fifth-generation communication systems; that with the progress of each telecom subscribers can connect to the Internet at a speed of 11 thousand Gbps. This makes the system very intelligent routing and data transfer with high speed and security. It is the process of separating hardware from software and the networking functions than a second. Software Defined Networking Foundation Network SDN by the standard theory of separation of control and data becomes smoother. As a result, thanks to the focus and planning, maintenance is largely automated. In this context, a system that is used to implement it, the nodes that are pasted packets are quite smart and intelligent algorithm based on the route and the destination node. This makes the system very intelligent routing and data transfer with high speed and security. In this article, we have tried to measure the QoS parameters in WiMAX networks and network performance 5G to compare them and examine the data transfer.
