Item A comparative analysis of BLE and 6LoWPAN for U-HealthCare applications(Institute of Electrical and Electronics Engineers Inc., 2013) Tabish, Rohan; Mnaouer, Adel Ben; Touati, Farid; Ghaleb, Abdulaziz M.For decades, there exist a variety of low-power wireless technologies deployed for healthcare applications such as Zigbee/IEEE802.15.4, Bluetooth, ANT, NFC, IrDA. However, the recently announced Bluetooth Low Energy (BLE) technology claims to offer many new compelling features and is expected to get wide adoption by many mobile manufacturers around the world and hence be included in daily life mobile devices. Therefore, it is important to provide future adopters with a thorough yet insightful evaluation of this technology as contrasted to competing ones in the market today. In this paper, we present such evaluation from an experimental point of view as well as referring to technical specifications from manufacturers. The discussion is geared toward assessing the extent to which theses technologies can meet the stringent requirements for u-healthcare applicability. BLE and 6LoWPAN showed greater potentials for such applicability in terms of power demand, bit rate and latency. Nevertheless, BLE was found to be most robust to obstacles and was operable using single coin cell. © 2013 IEEE.Item Embedded gateway services for Internet of Things applications in ubiquitous healthcare(Institute of Electrical and Electronics Engineers Inc., 2014) Rasid, Mohd Fakhrin Ab; Musa, Wan Mardiana Wan; Kadir, Nurul Ashikin Abdul; Noor, A. S. M.; Touati, Faisal; Mehmood, Waiser; Khriji, Lazhar; Al-Busaidi, Asma; Mnaouer, Adel BenThe continuous advancement in computer and communication technologies has made personalized healthcare monitoring a rapidly growing area of interest. New features and services are envisaged, raising users' expectations in healthcare services. The emergence of Internet of Things brings people closer to connect the physical world to the Internet. In this paper, we present embedded services that are part of a ubiquitous healthcare system that allows automated and intelligent monitoring. The system uses IP connectivity and the Internet for end-to-end communication, from each 6LoWPAN sensor nodes to the web user interface on the Internet. The proposed algorithm in the Gateway performs multithreaded processing on the gathered medical signals for conversion to real data, feature extraction and wireless display. The user interface at the server allows users to access and view the medical data from mobile and portable devices. The ubiquitous system is exploring possibilities in connecting Internet with things and people for health services. © 2014 IEEE.Item Towards u-health : an indoor 6LoWPAN based platform for real-time healthcare monitoring(Institute of Electrical and Electronics Engineers Inc., 2013) Touati, Farid; Tabish, Rohan; Mnaouer, Adel BenUbiquitous healthcare is the key to handle the challenges of the growing population around the world. A variety of u-healthcare systems have been developed using various short-range technologies and proprietary protocols which include Zigbee and bluetooth. With all these protocols, interoperability of smart devices remains a challenge. 6LoWPAN as an open standard has recently evolved to provide one common platform on the top of IEEE802.15.4 for low power devices and to mitigate this interoperability problem. In this paper, we present a novel 6LoWPAN based communication platform for next-generation u-healthcare system. The system integrates three nodes forwarding data to an edge router in order to provide real-time monitoring of the patient's ECG, temperature, and acceleration. A PC connected to the edge router acts as a two-directional Gateway between 6LoWPAN and internet. A new gateway application, listening to UDP packets from the 6LoWPAN nodes via the edge router along with any TCP client request from the internet, is developed. Thereby, any remote PC can connect to the gateway using TCP/IP by just connecting to the IP address and dedicated port of the gateway, fostering then ubiquity as well as Internet of Things. Nevertheless, the user can send instructions to any node where the application running on the gateway translates the command to a particular node. In our case, we used a Labview program to provide this connectivity. The whole system was tested successfully for different ECG rates using an ECG simulator. The received waveforms were found identical to those shown by a high-resolution scope wired to the ECG signals. © 2013 IEEE.
