Abstract

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

Abstract

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.
