An Experimental-Based Analysis of Inter-BAN Co-Channel Interference Using the kappa-mu Fading Model

Abstract

In this communication, we empirically study and model the impact of co-channel interference and background noise (BN) on a body area network (BAN) operating at 2.48 GHz using the extremely generalized kappa-mu fading model. The BAN measurements considered three nodes with the signal-of-interest (SoI) forming the link between two wearable devices located on the front-central-chest and front-central-waist of an adult male, while an interfering signal emanated from a third wearable device that was located on the front-central-waist of an adult female. Three environments were considered which are indicative of different environmental multipath conditions likely to be encountered by everyday BAN users, namely, an anechoic chamber, a reverberation chamber and an indoor laboratory. As well as this, the influence of different human mobility scenarios was studied. Utilizing the kappa and mu parameter estimates, we then provide some useful insights into the outage performance of BAN systems in the presence of BN when both the SoI and the interferer undergo kappa-mu fading.
