Exploiting smart e-Health gateways at the edge of healthcare Internet-of-Things
Amir M. Rahmani,Tuan Nguyen Gia,Behailu Negash,Arman Anzanpour,Iman Azimi,Mingzhe Jiang,Pasi Liljeberg +6 more
TL;DR: This paper proposes to exploit the concept of Fog Computing in Healthcare IoT systems by forming a Geo-distributed intermediary layer of intelligence between sensor nodes and Cloud and presents a prototype of a Smart e-Health Gateway called UT-GATE.
Proceedings ArticleDOI
Fog Computing in Healthcare Internet of Things: A Case Study on ECG Feature Extraction
Tuan Nguyen Gia,Mingzhe Jiang,Amir-Mohammad Rahmani,Tomi Westerlund,Pasi Liljeberg,Hannu Tenhunen +5 more
TL;DR: Electrocardiogram feature extraction is chosen as the case study as it plays an important role in diagnosis of many cardiac diseases and fog computing helps achieving more than 90% bandwidth efficiency and offering low-latency real time response at the edge of the network.
Proceedings ArticleDOI
Smart e-Health Gateway: Bringing intelligence to Internet-of-Things based ubiquitous healthcare systems
Amir-Mohammad Rahmani,Nanda Kumar Thanigaivelan,Tuan Nguyen Gia,Jose Granados,Behailu Negash,Pasi Liljeberg,Hannu Tenhunen +6 more
TL;DR: This paper exploits the strategic position of such gateways to offer several higher-level services such as local storage, real-time local data processing, embedded data mining, etc., proposing thus a Smart e-Health Gateway.
Journal ArticleDOI
Using Ant Colony System to Consolidate VMs for Green Cloud Computing
Fahimeh Farahnakian,Adnan Ashraf,Tapio Pahikkala,Pasi Liljeberg,Juha Plosila,Ivan Porres,Hannu Tenhunen +6 more
TL;DR: The proposed ACS-based VM Consolidation (ACS-VMC) approach finds a near-optimal solution based on a specified objective function and outperforms existing VM consolidation approaches in terms of energy consumption, number of VM migrations, and QoS requirements concerning performance.
Journal ArticleDOI
Internet of things for remote elderly monitoring: a study from user-centered perspective
TL;DR: This paper studies the IoT-enabled systems tackling elderly monitoring to categorize the existing approaches from a new perspective and to introduce a hierarchical model for elderly-centered monitoring.
