In this work, finite-difference time-domain was used for the investigation of dynamic wireless body area network
channel characteristics during walking, thus accounting for dynamic aspects and body postures. This involves the
study of on-body, off-body, and body-to-body communication in an empty environment, at the center frequency of
2.45 GHz. The channels were investigated in terms of fade variation and their corresponding amplitude distributions.
For on-body channels, the fade variation was found to be periodic, with larger fade variations for the channels
involving the nodes at the hand and thigh. For off-body and body-to-body channels, channels with the absence of
line of sight experienced constructive and destructive interference as the distance between the end nodes changes,
resulting in larger fade variations. For the amplitude distribution of the channels, a multivariate normal distribution
was considered. The distribution has the capability of modeling channels jointly which makes it easier for network
analysis and was considered because of the significant correlation between the channels. The resulting estimated
multivariate distributions fit well with the simulated data, for on-body, off-body, and body-to-body channels |
