Body Area Networks: A Data Sharing and Use Model Based on the Blackboard Architecture and Boundary Node Discovery

Abstract

Body area networks are growing in use and complexity, with many individuals carrying around several devices that have interconnection capabilities. Devices may offer internet connectivity, storage, media recording and playback, image or audio capture, and numerous other capabilities. Some may house recently captured data; others may house users’ older data or have direct or indirect access to data from subscription providers. Users may enter into range of other providers who may provide a myriad of services ranging from information to environmental interaction. While limited interoperability standards (such as Bluetooth) exist, these are not full stack connection solutions. In many cases, users are left unable to access (or unsure as to how they access) services available from their devices or infrastructure providers. This paper presents a paradigm for data sharing and use as part of a Blackboard Architecture boundary node discovery (BABND) protocol for defining available data and other services. The basics of the BABND protocol are described and its use for data sharing is detailed. The efficacy of this protocol is evaluated through the consideration of case studies that are presented.
