Abstract

Body Area Networks (BANs) is of importance for telemedicine and telehealth services, so cause attractiveness for engineers. Since the wireless sensor nodes adhere to the human body surface, the human body unavoidably absorbs the electromagnetic wave which may be harmful, so investigating the specific absorption rate becomes significant in exploration of BANs. Additionally, the BAN channel is different with the common wireless channel because the communication distance is very short and the electromagnetic wave propagates along the body surface. In this paper, we focus on calculating Specific absorption rate (SAR) values and exploring wireless channel in different frequencies. Firstly, we design a model approximate to human tissues including skin, fat, muscle and internal organs, then compute SAR values b placing antennas in 900MHz, 2.4GHz and 5GHz. Then we provide theoretical analysis for the BAN channel. A model is constructed to calculate the path loss values in different distance and a power delay profile is proposed to generate frequency response of human body communication in UWB frequency.
