“…This is in alignment with ADVENT platform envisioned as a system able to accommodate a wide range of data including health related, but also ambient or security related information [46]. Furthermore SPP offers a wider range of applicability and support since it offers compatibility with devices not supporting HDP (which in various references is depicted as not as widely adopted as anticipated [47,48]or not offering anticipated advantages over SPP [49]). Finally, we feel that SPP is a more adequate selection targeting future Bluetooth versions (i.e.…”
The ability to deploy efficient and versatile WSN networks in the home environment is and will remain in the years to come a cornerstone objective in wireless networking. Respective services are continuously expanding requiring novel design and implementation approaches able to cover all relative present and even more importantly future requirements. This paper aims to present and convey knowledge and experience gained from such an effort in the context of home monitoring. Respective discussion covers all relative aspects and analyzes all critical challenges addressed ranging from identification and specification of the main requirements, to possible implementation approaches considered and finally the actual development undertaken. The final outcome considering the WSN home monitoring infrastructure as well as extracted knowledge and practical conclusions can be proven useful for further extending such an endeavour or even pursuing a different approach.

“…5. Description of how the "read clock" command is processed by a Bluetooth module [22] a Health Device Profile (HDP), SPP has been chosen since for data streaming the two profiles are comparable in terms of packet loss [21].…”
Wireless Body Area Networks (WBANs) can take advantage of many wireless protocols. Among them, Bluetooth is a good candidate since its widespread adoption guarantees compatibility with a number of devices and significantly reduces development time. In most cases data collected from different sensors on different nodes need to be synchronized. We present a synchronization protocol that makes use of Bluetooth piconet internal clock to achieve near-millisecond accuracy with minimal radio communication overhead. Experimental results show that Bluetooth low power modes does not affect negatively accuracy, but improves it, obtaining less power consumption and higher synchronization accuracy.
“…Relaying on standardizations like Bluetooth HDP and IEEE 10073 enables modular data acquisition that is easy to extend. A comparison between Bluetooth HDP and the Serial Port Profile (SPP) [12] shows that the transmission energy of the two profiles is similar, however HDP has the advantage of plug-and-play interoperability.…”

The progress of telematics (=Telecommunication + Automation + Informatics) methods promisesin tele-medicine applications increasing quality of treatment at reduced costs. At the two example cases of COPD (Chronic Obstructive Pulmonary Disease) and of Dialysis a related sensor equipment to characterize the health status, as well as equipment for continuous and safe data transmission are presented. Data processing at a tele-service center has to filter information,such that only the critical cases are confronted to the doctors. Challenges, system architecture and first experiences of this tele-medicine approach for remote monitoring of patients are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
