Abstract: | Recent advances in microelectronics and integrated circuits, system-on-chip design, wireless communication and intelligent
low-power sensors have allowed the realization of a Wireless Body Area Network (WBAN). A WBAN is a collection of low-power,
miniaturized, invasive/non-invasive lightweight wireless sensor nodes that monitor the human body functions and the surrounding
environment. In addition, it supports a number of innovative and interesting applications such as ubiquitous healthcare, entertainment,
interactive gaming, and military applications. In this paper, the fundamental mechanisms of WBAN including architecture and
topology, wireless implant communication, low-power Medium Access Control (MAC) and routing protocols are reviewed. A comprehensive
study of the proposed technologies for WBAN at Physical (PHY), MAC, and Network layers is presented and many useful solutions
are discussed for each layer. Finally, numerous WBAN applications are highlighted. |
