AB - The emerging Wireless Body Area Network (WBAN) has a great potential to strengthen health care sector, as it paves ways for the development of new services and applications. In making WBAN technically feasible, high Signal to Noise ratio (SNR) and low outage probability plays a vital role. In vivo communication is one where communication between living beings can be carried out wirelessly. It utilizes data gathered in real time for quick and accurate responses in emergency situations. To fully benefit from and further explore the potentiality of WBANs for realistic applications, it is critical to analyze the performance of in vivo WBAN communication over different frequency bands. Over the past many years, Medical Implant Communication System (MICS) band has extensively been used for implant medical applications and Terahertz (THz) band shows promising link capability to support increased data rates. In the proposed work, performance of an in vivo WBAN system, at MICS and Terahertz frequencies based upon IEEE 802.15.6 channel models (CM), CM1 and CM2 has been assessed. The effect of incorporating cooperative communication for in vivo WBAN is then presented to see how it enhances the network performance at both the bands. The impact on the system’s SNR and outage probability is investigated for number of relays. The outage behavior of amplify and forward cooperative communication with multiple relays is investigated over a Rayleigh fading channel. Results show considerable increase in the system SNR and decrease in outage probability with increase in number of relays, which strongly indicates the possibility of incorporating cooperative communication to elevate the performance of in vivo WBAN at both MICS and terahertz frequencies. Further, nature inspired optimization is done to reduce the outage probability. Results show that the projected technique surpasses the non-optimized technique and ensures favorable results. The results achieved at THz band have also been compared to that obtained at MICS band and it is demonstrated that better performance can be achieved at THz band by incorporating cooperative communication in the network.
