A Preliminary Two Dimensional Model for Intra-body Communication of Body Sensor Networks

Intra-body Communication (IBC) is an emerging and interesting communication technique for Body Sensor Networks (BSN). It employs the human body as communication channel for transmitting signals in order to reduce electromagnetic interference and abundant cables often appeared in home health care devices. Currently researches, aim at developing the application of IBC in BSN, have been conducted by other researchers to demonstrate the feasibility and capabilities of IBC. In this paper, a preliminary two dimensional model for IBC is developed. This model attempts to provide insight of transmitting electrical signal through human body and forms a simple basis for developing IBC applications. Simulation results reveal the potential distribute in different type of biology tissues with different conductivities at low frequency and finally, experimental measurements validate the correctness of the model.
