KABLOSUZ YERALTI ALGILAYICI AĞLAR İÇİN DÜĞÜM İLETİŞİMİNDE DERİNLİK FAKTÖRÜNÜN ANALİZİ

Kablosuz yeraltı algılayıcı ağlar, yeni bir araştırma alanı olarak karşımıza çıkmaktadır. Akıllı sulamadan, güvenlik ve yardım tabanlı yönlendirmeye kadar birçok mühendislik uygulamasında yaygın bir şekilde kullanılmaktadır. Kablosuz yeraltı algılayıcı ağların uygulama alanlarının bir kısmı tünel, mağara, vb. yeraltı boşluklu alanlardan oluşurken, bir kısmı da yeraltı boşluksuz katı ortamlardan oluşmaktadır. Bu bağlamda, kablosuz yeraltı algılayıcı ağlar tarımsal amaçlı olarak son zamanlarda büyük önem kazanmaya başlamıştır. Bu makale çalışmasında, toprağın yeraltı-yeraltı ve yeraltı-yerüstü kablosuz yeraltı algılayıcı düğüm iletişimine olan etkisi matematiksel olarak benzetim modeli ile incelenmiştir. Ağ yapısının başarımını değerlendirmek amacıyla, alınan sinyal gücü ve yol kaybı parametreleri ele alınmıştır. Derinlik mesafesi arttıkça, iletişimde yaşanan yol kayıplarının da arttığı gözler önüne serilmiştir. Elde edilen başarım değerlendirmesi sonuçları, kablosuz yeraltı algılayıcı ağlarda derinlik tabanlı iletişim için farklı gönderici gücü ile sinyal iletimi gerekliliğini ortaya çıkarmaktadır.

ANALYSIS OF DEPTH FACTOR IN NODE COMMUNICATION FOR WIRELESS UNDERGROUND SENSOR NETWORKS

Wireless underground sensor networks are a new area of research. It is widely used in many engineering applications, from smart irrigation to security and help based routing. Some of the application areas of wireless underground sensor networks are underground with space such as tunnel, cave, etc. while some consists of no spaced underground solid areas as well. In this context, the wireless underground sensor networks have recently become very important for agricultural purposes. In this paper, the effect of soil on underground-underground and underground-surface wireless underground sensor node communication has been investigated with a mathematical simulation model. In order to evaluate the performance of the network structure, the received signal strength and path loss parameters are discussed. As the depth distance increases, the increase in path loss of communication has been revealed. The acquired performance evaluation result reveals the need for signal transmission with different transmitter power for depth-based communication in wireless underground sensor networks.
