Recently, a concept of linear wireless sensor networks (LWSNs) has attracted much attention. For such networks, one of the key challenges in sensor node design is to couple transceiver modules with bidirectional antennas placed back-to-back for opposite radiation. As is known, simply, this can be achieved by using well-known coupling options like radio frequency (RF) switch or splitter. However, it is important to decide between two seemingly equally good options according to the system requirements such as RF performance, power consumption, and cost. Therefore, this study aims to comparatively assess these options from the system level point of view to find out what advantages or disadvantages either provides as per the other from widespread use of them in a LWSN-based cathodic protection monitoring of oil and natural gas pipelines in extreme environments. Preliminary field tests are also conducted to validate the efficiency of coupling options for LWSN links. Results show that RF splitter offers low power consumption and cost whereas RF switch has advantages of low loss. Thus, it is believed that this study may provide useful insights to design bidirectional sensor links for LWSNs.
Kablosuz Ağlarda Arka Arkaya Olan Antenlerin Bağlantı Seçeneklerinin Karşılaştırılması

Bu tez çalışması, çift yönlü sensör düğümlerinin birbirleriyle bağlantısını sağlamayı amaçlamaktadır. Bir alıcı-verici yonga setine sahip olan arka arkaya yönsel antenlerin kablosuz sensör linki oluşturmak için antenler arasındaki bağlantı, RF Anahtarı ve RF Ayırıcı/Birleştirici tasarımları kullanarak sağlanmıştır. Bu iki tasarımın, performans değerlendirmeleri amaç olarak belirlenmiştir. Görüş mesafesinde ve görüş hattı dışındaki ortamlarda ölçümler alınmıştır. Ölçüm sonucunda elde edilen veriler toplam maliyet, enerji tüketimi ve erişebilecek maksimum mesafe bakımından değerlendirilmiştir.
