ANALYSIS OF VARIOUS PROTOCOLS IN WIRELESS BODY AREA NETWORKS (WBAN)

A Body Area Network is a system of computing devices located in close proximity to the human body which coordinates and cooperates for the benefit of the user. Body Area Networks have evolved out of sensor network technology and biomedical engineering. In this paper we discuss various aspects of Body Area Networks, introduction section deals with various concepts associated with computer networks and some supporting technologies of Wireless Body Area Networks (WBANs). Section 2 deals with the various definitions of Body Area Networks (BANs) followed by the types of BAN in section 3 and system architecture in section 4. Section 5 gives the draft guidelines by IEEE 802.15.6 for a communications standard for BAN, the next two sections list out the applications and current research trends of BAN followed by the conclusion.
