Performances Enhancement in Wireless Body Area Network (WBAN)

Wireless body area network (WBANs) is a recent and emerging technology for medical health monitoring wireless communication system. Its provides short range communication between the body surface and the wireless access point. Channel characteristics of WBAN is very peculiar one compare to others wireless channels, particularly when human body rotates and interferences of others human body shadowing and their own shadows. In this papers analysis the characteristics of recently proposed off-body WBAN channels can be achieved by modeling of channels and improved bit error performances when human body rotates as well as shadowing. In order to avoid the above demerits it is important to obtain the improved bit error performances, additionally another receive antenna is attached to the back side of human body. And also various diversity schemes where used to analyze the each performances of WBAN. Index Terms—wireless body areas networks (WBANs), off body channels, Rician K-factor, Diversity schemes.
