Channel Modeling in Wireless Body Area Networks

Abstract

[eng] In this thesis, Wireless Body Area Networks channel modeling is studied and analyzed. This thesis goes through the standards IEEE 802.15.6 and SmartBAN as introduction to the field. Next, we perform a thorough WBAN channel analysis and later comparison of the di↵erent techniques and implementations based on characteristics such as fading (i.e., small and large scale) and human body evaluations under di↵erent activities. Simulations are undertaken to show and validate di↵erent hypotheses at higher level. For instance, a path loss simulation is performed as well as shadowing e↵ects. Results show that path losses increase as a distance function as expected, (general loss increase due to shadowing where a di↵erentiation between line of sight and no line of sight is made). In conclusion, the analysis from channel modeling perspective is summarized and guidelines for future works are provided.
