Within the broad theme of wireless healthcare systems, this paper focuses on emergency interventions. Specifically, we address one of the aspects of this problem, namely sensing and transmitting to a health center data regarding an emergency status. No dedicated infrastructure is assumed—rather, the premise is that existing wireless networks be utilized. Our goal is to enable quick and reliable access whenever an emergency arises. For system design, we describe an integrated solution based on the use of wireless/mobile technologies and of smartphones integrated by ad hoc sensors. We examine the possible use of licensed or unlicensed spectrum through two separate techniques: Interweaved Cognitive Radio and a novel version of Interference Alignment, that we call Interference Priority and is tailored to the specific problem of this paper. Validation based on the behavioral aspects of the system is also discussed.
