TLDR
It is found that components diffracting around the body are well modeled using correlated log normal variables, and a Nakagami-m distribution can be used to incorporate the influence of arm motions.Abstract:
Body worn wireless sensors for monitoring health information is a promising new application. In developing these sensors, a communication channel model is essential. However, there are currently few measurements or models describing propagation around the body. To address this problem, we have measured electromagnetic waves near the torso and derived relevant statistics. We find that components diffracting around the body are well modeled using correlated log normal variables, and a Nakagami-m distribution can be used to incorporate the influence of arm motions. We have implement this model and evaluated it in terms of important communication metrics. This paper describes body area propagation statistics and proposes a suitable computer model implementation.read more

Propagation Models for Body-Area Networks: A Survey and New Outlook
TL;DR: A goodness-of-fit criterion that directly trades off model error and complexity is presented, which gives a new outlook for channel modeling and demonstrates that through significant simplification of individual link propagation models for body-area networks, it is possible to combine link models with only a few parameters.
