Magnetic Induction-Based Wireless Underground Waveguide Modelling and Its Parameters
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2014, Vol 4, Issue 3
Abstract
Wireless Underground Communication Networks (WUCN’s) consist of wireless devices that operate below the ground surface Wireless underground and terrestrial communication is mainly differentiated by signal propagation medium. Wireless communication is very challenging in case of underground environment as propagation medium is no longer air but includes soil, rock and water. There are some obstacles which unable well established wireless communication techniques work well using electromagnetic (EM) waves in this environment. This obstacles include High path loss, Dynamic channel condition and Large antenna size. With the help of Magnetic Induction (MI), new techniques create a constant channel conditions and provides communication even with small size coil. Realizing this concept of Magnetic Induction, it emerged that it can solve two of the three obstacles which are dynamic channel condition and large antenna size however may still cause even higher path loss. A complete characterization of the underground MI communication channel is provided in these references. The MI waveguide technique for communication is developed in order to reduce the MI path loss based on Channel Modelling. Quantitative comparison is being done between the performance of the traditional EM wave systems, the current MI systems and improved MI waveguide system. The conclusions reveal that improved MI waveguide system has much lower path loss than the other two cases for any channel conditions.
