It can get very complicated! As @Walter Roberson pointed out, the mode of signal propagation (through body or on skin) is an important consideraiton. If you assume "thorugh" the body, then Euclidean distance between nodes will be a good first approximation for distance. A next level of complicaiotn will be how much of that Euclidean distance is body tissue and how much is air. I recommend that you ignore the body versus air distinction initially, to keep things less complicated. Figure 10 of this article is informative. Model the body as a set of segments with joints where the segments touch. Each segment may be a cylinder or ellipsoid, and standard dimensions or subject-specific dimensions. For example, see chapter 4 and appendix A of Winter, Biomechanics and Motor Control of Human Movement, 4th ed., 2009. NASA and the US Air Force have a long history of modeling the body in various postures and have collected much data (originally all white males, but more diverse now). See here for example.
