The Qualitative Study on Input – Output Channel Configurations in Wireless Body Area Network

Abstract Increasing interest in wireless networks and the electrical devices with the help of semiconductor technology has empowered the active participation of people in the development of Wireless Body Area Networks. Sensor network’s environment for using free space is different from that of Wireless Body Area Network as it transmits signals through body parts. There are lots of areas which need to be taken care of during the transmission of signals. One of the predominant points is fading.This manuscript deals with simulating transmissions over fading channels and presents a comparative study of various input-output channel characteristics in Wireless Body Area Network. The power profile of Wireless Body Area Network with various input-output channel configurations is generated using Weibull characteristics according to NICTA’s (previously known as National ICT Australia Ltd) measurement in MATLAB software. It is known that as the distance increases fading occur in the signal as well as in the channel. This work basically deals with the various type of power profile which will be achieved by changing input and output channel configurations. Moreover, channel’s power profile has been plotted to get mean fading values using carrier frequency, relative body movement, and scattering density. Here few of the mitigation methods to remove the effect of fading are also discussed.
