Link Energy Minimization in Magnetic Induction based Non-Conventional WSNs

In non-conventional media (underground and underwater environment), wireless signal propagation is not advantageous by means of electromagnetic (EM) waves due to problems like high path loss, size of antenna and dynamic channel conditions. Hence, an alternative communication technique of magnetic induction (MI) based communication is developed which is highly suitable for efficient communication in this media because of its promising features. In any wireless sensor network (WSN), energy is a limited reserve. The total energy consumption of the network can be significantly minimized by clustering technique. Moreover, link energy minimization plays an important role in terms of energy-efficiency of WSN. Hence in this paper, unconstrained energy consumption model of different modulation techniques is applied in MI based non-conventional WSN. The performance of this proposed model is observed for three different media (dry soil (DS), sedimentary rock (SR) and sea water (SW)).
