Performance of Electromagnetic Nanonetwork under relaying for plant monitoring

Abstract

Recently, Nanonetworks has been envisioned as a predominant technology. Applications of whose ranges from environment to agriculture and biomedical to military, almost in every field of human life. It plays a vital role in crop monitoring for high-resolution agriculture and in detection of emitted volatile organic compounds. However, sensing range of an individual nanosensor is limited. Multi-hop, relay system can be used to enhance the transmission range of nanosensor based Nanonetworks. This manuscript presents various performance measure of an Electromagnetic Nanonetworks under Amplify-and-Forward (AF) relaying for plant monitoring. Specifically, proposes closed form expressions for Average Error Rate and Spectral Efficiency (SE) of Differential Binary Phase Shift Keying (DBPSK) and Differential Quadrature Phase Shift Keying (DQPSK) modulation schemes of Nanonetworks under dual AF relaying. It is worthful to mention that plant scenarios and hence fading model for different types of plant is different. Therefore, in analysis fading channel from source to relay (S-R) is taken as Fox’s H (FH) function which realizes different fading models, such as EGK, Fisher-Snedecor (FS) distribution and Alpha-Mu fading models, as its special cases to represent different plant scenarios. Whereas, fading model from relay to destination (R-D) is taken as Generalized-Gamma (GG). It is observed that an increase in the value of severity and/or shaping parameters decreases the average error rate. On the other hand, converse is true for the spectral efficiency. Analytical results show perfect agreement with simulation.
