COMPARATIVE ANALYSIS OF THREE INDOOR MODELS IN TERMS OF ENERGY LOSS & BER USING DIFFERENT CONSTRAINTS

Abstract

In indoor mobile networks the investments are highly based on spectrum availability and its associated
authorization options. Some physical properties of the network like spectrum type, propagation type are set up when the
network environment is defined which control the network communication. There are number of constraints which affect
the communication over network and all the constraints depend upon network type, its topology and type of
communication. It is required to define the network under defined constraints to obtain the optimum output from the
network. The application of constraint satisfaction programming is used in the indoor environment to predict the signal
processing. In this paper communication analysis on indoor mobile network is focused which considered small area like
a room or the building. A comparative analysis has been done in the presented work in terms of BER and energy loss for
three indoor propagation models named Rayleigh propagation model, Friis propagation model and Log-distance
shadowing propagation model using distance, density and energy parameters which define the constraints and reduction
or BER in indoor mobile network . Most of the radio simulators predict only the mean power but fading also affects the
system performance so noisy channel also considered in this work so that optimum output is obtained in indoor
environment.
