TL;DR: It is shown that, despite the importance of context-awareness in WBAN applications, there are limited solutions available, particularly at the MAC layer, and a discussion on open research challenges for future context-aware WBANs is held.
Abstract: Wireless Body Area Network (WBAN) applications help reduce medical costs and improve people's quality of life by monitoring a user's biological signals via wearable and implantable wireless sensors. In order to satisfy burgeoning requirements, context-aware solutions are needed, thus allowing the system to adapt to changes in the user's mood, mental states, biological signals, and the environment. Thus, contextual information must be measured alongside biological signals in order to characterize and understand the current situation to adapt the system. With these issues in mind, this survey presents an overview of context-aware solutions at the Medium Access Control (MAC) and application layers. A clear distinction between medical and non-medical applications is made and some promising latest commercial WBAN products are highlighted. We show that, despite the importance of context-awareness in WBAN applications, there are limited solutions available, particularly at the MAC layer. The survey concludes with a discussion on open research challenges for future context-aware WBANs.

TL;DR: WatchMe as discussed by the authors is a personal communicator with context awareness in a wristwatch form; it is meant to keep intimate friends and family always connected via awareness cues and text, voice instant message, or synchronous voice connectivity.
Abstract: WatchMe is a personal communicator with context awareness in a wristwatch form; it is meant to keep intimate friends and family always connected via awareness cues and text, voice instant message, or synchronous voice connectivity. Sensors worn with the watch track location (via GPS), acceleration, and speech activity; this is classified and conveyed to the other party, where it appears in iconic form on the watch face. When a remote person with whom this information is shared examines it, their face appears on the watch of the person being checked on. The working prototype was used as the focus of interviews to gauge the desirability of such a device.

TL;DR: The iHospital system is built to support the often intense coordination of operations in a large hospital, and to this end it incorporates location tracking, a context-awareness system, large interactive displays, and mobile phones.
Abstract: This article reports our experiences with deploying the iHospital system, a hospital scheduling and awareness system. We built the system to support the often intense coordination of operations in a large hospital, and to this end, it incorporates location tracking, a context-awareness system, large interactive displays, and mobile phones

TL;DR: This paper developed a prototype system and experiment to show the possibility of the mechanism proposed in this paper, and found that the mechanism with multi-agents yields more pay-off, total sales, and wins than the system without those features.
Abstract: Comparative shopping is a promising web service in the field of mobile commerce. This paper aims to propose a context-aware comparative shopping. Multi-agent intelligent architecture is adopted to implement the autonomous negotiation mechanism between buyers and sellers. To automatically estimate user preferences to determine the best purchase, case-based reasoning and negotiation mechanism are utilized. We developed a prototype system and experiment to show the possibility of the mechanism proposed in this paper. We found that our mechanism with multi-agents yields more pay-off, total sales, and wins than the system without those features.
