Abstract

Wireless communication technologies are developing directly proportional to the need and demand for these technologies. Therefore, studies in this direction are gaining importance day by day. The increase in applications with heavy data traffic, such as social networks, file sharing, and multimedia communication, increases the need for spectrum, which is essential in daily wireless communication. Current wireless communication devices work with a fixed spectrum assignment technique and generally use certain parts of the spectrum. Cognitive Radio Networks (CRNs) dynamically access the unused and idle parts of the spectrum, allowing the selection of the most appropriate communication channel. It is crucial to determine the packet size used in communication between users in order to reduce the energy consumption resulting from frequency changes among CR users. Because CR users dynamically change their frequencies, reducing the time remaining in the time slots allocated to them for data communication. In this decreasing time, it is also crucial to determine the most suitable package size. In this study, the effects of packet length values on energy efficiency in CRNs were investigated through numerical analyzes for different variable parameters in a Python simulation environment. Investigations made with these parameters can be summarized as follows: The impact of unit channel change power and duration on the total energy according to the packet size, the impact of different time zones on the total energy according to the packet size, the impact of the unsuccessful transmission rate on the total energy according to the packet size, and the variation in the packet sending/receiving efficiency according to the change in the whole cognitive time.

Özet

Kablosuz iletişim teknolojileri, bu teknolojilere olan ihtiyaç ve taleple doğru orantılı olarak gelişmektedir. Dolayısıyla, bu doğrultuda yapılan çalışmalar günden güne önem kazanmaktadır. Sosyal ağlar, dosya paylaşımı ve çoklu ortam iletişimi gibi yoğun veri trafiği olan uygulamaların artışı, kablosuz iletişimde önemli bir yeri olan spektruma olan ihtiyacı günden güne artırmaktadır. Güncel kablosuz iletişim cihazları, sabit bir spektrum atama tekniği ile çalışmakta ve genellikle spektrumun belirli bölümlerini kullanmaktadır. Bilişsel Radyo Ağları (Cognitive Radio Networks, CRN'ler), spektrumun kullanılmayan ve boşta olan bölümlerine dinamik olarak erişerek en uygun durumdaki iletişim kanalının seçilmesini sağlamaktadır. CR kullanıcıları arasında frekans değişimi sonucu ortaya çıkan enerji tüketiminin azaltılabilmesi amacıyla, kullanıcılar arasındaki iletişimde kullanılan paket boyutunun belirlenmesi önem taşımaktadır. Çünkü, CR kullanıcılarının frekanslarını dinamik olarak değiştirmeleri, kendilerine veri iletişimi için ayrılan zaman dilimlerinde kalan süreyi azaltmaktadır. Azalan bu süre içerisinde en uygun paket boyutunun belirlenmesi önem arz etmektedir. Bu çalışmada, paket uzunluk değerlerinin CRN'lerdeki enerji verimliliğine etkileri, Pyhon benzetim ortamında farklı değişken parametreleri için nümerik analizler yoluyla incelenmiştir. Bu parametrelerle yapılan incelemeler; birim kanal değişim gücünün ve süresinin paket boyutlarına göre toplam enerjiye etkisi, farklı zaman dilimlerinin paket boyutlarına göre toplam enerjiye etkisi, başarısız gönderim oranın paket boyutlarına göre toplam enerjiye etkisi ve toplam bilişsel sürenin değişimine göre paket gönderim/alım veriminin değişimi şeklinde özetlenebilir.
