Özet:

 The most important problem of IoT networks, which have the potential to drive 6G technology, is the battery life of devices. Frequently changing or charging the batteries of billions of IoT devices that can be used in next-generation communication systems is both costly and inconvenient, making it impractical. Moreover, this is far from the goal of establishing a low energy and low latency communication protocol with high bit rate. In this paper, a full-duplex symbiotic network with two devices based on the technique of harvesting energy from electromagnetic waves is proposed to overcome the existing problem and increase the bit rate. Two different scenarios are considered in this work where resource allocation is determined in terms of time and power. In the non-cooperative scenario, the wireless devices try to reach their own communication destination, while in the cooperative scenario, the devices transfer information in a symbiotic relationship. In the proposed system, the full-duplex power station FDPS has two antennas and acts as both a transmitter and a receiver. Wireless devices are not only capable of transmitting a typical signal, but also capable of backscatter communication, which is a method of mapping the bit sequence to radio frequency waveforms, which are a type of electromagnetic wave by changing the antenna load impedance and adjusting the antenna reflection coefficient. In this model, where the operating states of wireless devices are determined according to the amount of energy they harvest, mathematical analysis is performed and the objective function of the system is obtained for both models. Then, the bit rate is maximized by allocating resources over power and time parameters. In the simulation results, the system performance is tested over different parameters. According to the findings, the low signal power of the FDPS seriously affects the communication of the remote device. In addition, using the system at very high frequencies caused some degradation in performance. Finally, the graphical results show that the cooperative scenario is less affected by the system parameters than the non-cooperative scenario and is superior in terms of performance.

 Altıncı nesil 6G teknolojisine yön verme potansiyeline sahip nesnelerin interneti IoT ağlarının en önemli sorunu cihazların pil ömrüdür. Gelecek nesil haberleşme sistemlerinde kullanılabilecek milyarlarca IoT cihazının pillerini sık sık değiştirmek veya şarj etmek, hem maliyetli hem de zahmetli olduğundan uygulama açısından pratik değildir. Ayrıca bu durum, yüksek bit hızında düşük enerji ve düşük gecikme süresine sahip haberleşme protokolü kurma hedefinden de çok uzaktır. Bu makalede, mevcut sorunun üstesinden gelmek ve bit hızını artırmak için elektromanyetik dalgalardan enerji hasat etme tekniğine dayalı iki kablosuz cihaza sahip çift yönlü simbiyotik bir ağ önerilmiştir. Zaman ve güç açısından cihazlara kaynak tahsisinin yapıldığı bu çalışmada iki farklı senaryo düşünülmüştür. İşbirliksiz senaryoda kablosuz cihazlar kendi haberleşme hedefine ulaşmaya çalışırken, işbirlikli senaryoda ise cihazlar simbiyotik bir ilişki içinde bilgi aktarımını gerçekleştirmektedirler. Önerilen sistemde çift yönlü güç istasyonu FDPS, iki antene sahip olup hem verici hem alıcı görevi görmektedir. Kablosuz cihazlar tipik sinyal iletimi yapma yeteneğine sahip olmanın yanında, anten yük empedansının değiştirilip anten yansıma katsayısının ayarlanarak bit dizisini elektromanyetik dalga türü olan radyo frekans dalga formlarına eşleme yöntemiyle geri saçılım haberleşme de yapabilmektedir. Kablosuz cihazların hasat ettiği enerjinin miktarına göre çalışma durumlarının belirlendiği bu modelde, matematiksel analizler yapılmış ve her iki model için sistemin objektif fonksiyonu elde edilmiştir. Daha sonra güç ve zaman parametreleri üzerinden kaynak tahsisi yapılarak bit hızı maksimize edilmiştir. Simülasyon sonuçlarında, farklı parametreler üzerinden sistem performansı test edilmiştir. Elde edilen bulgulara göre, FDPSnin sinyal gücünün düşük olması, uzak cihazın iletişimini ciddi manada etkilemektedir. Ayrıca sistemi çok yüksek frekanslarda kullanmak performansta bir miktar düşüşe sebep olmuştur. Son olarak, işbirlikli senaryonun işbirliksiz senaryoya göre sistem parametrelerinden daha az etkilendiği ve performans açısından daha üstün olduğu grafiksel sonuçlarda gösterilmiştir.
