Coverage Probability using EM waves for UWSN in Shadowing Environment

Abstract

A channel model is introduced which considers shadowing fading on coverage probability for underwater sensor networks using electromagnetic signals. A model for finding the probability of detection and coverage using log normal shadowing fading has been derived. A comparative study between the sensing channel model and existing model for terrestrial sensor networks is also presented. It is observed the introduced sensing channel model uses far less number of sensors for coverage of underwater networks in comparison to terrestrial networks. General TermsSensor Networks

Review on research challenges and strategies in underwater sensor networks

“…The authors have given a derivation of coverage probability in the presence of shadowing environment based on the received signal strength using a stated mathematical model. It is cleared that more be the coverage, the data reception by all the sensors that fall in its communication range also be much better [9]. In order to minimize coverage overlaps, nodes have to be located far enough from each other.…”
