A novel energy-driven computing paradigm for e-health scenarios

Abstract

A first-rate e-Health system saves lives, provides better patient care, allows complex but useful epidemiologic analysis and saves money. However, there may also be concerns about the costs and complexities associated with e-health implementation, and the need to solve issues about the energy footprint of the high-demanding computing facilities. This paper proposes a novel and evolved computing paradigm that: i) provides the required computing and sensing resources; ii) allows the population-wide diffusion; iii) exploits the storage, communication and computing services provided by the Cloud; iv) tackles the energy-optimization issue as a first-class requirement, taking it into account during the whole development cycle. The novel computing concept, and the multilayer top-down energy-optimization methodology, obtain promising results in a realistic scenario for cardiovascular tracking and analysis, making the Home Assisted Living a reality.

Power-awareness and smart-resource management in embedded computing systems

“…The policies applied yield to savings of 23.4% in the overall application. All possible combinations and further energy-aware policies, including SLURM allocation optimization, and improved VM consolidation will be applied in future work, following the methodology in [27].…”

Simplified server model to simulate data center cooling energy consumption

“…The CPU dynamic power P dynamic can be expressed in terms of the CPU utilization u CPU -that is, in proportion to the CPU clock frequency f -if the CPU supply voltage E dd and effective switching capacitance C e are constant [30,35], as shown in Eq. (2):…”

“…Recent high-density servers have applied variable airflow control (which maintains a minimum server airflow to conserve server cooling fan energy [27]) and a CPU die temperature between 75 and 90 • C (wherein CPU reliability is guaranteed [35]) [32,36,37].…”

WSN Based Wheeze Detection Systems for Diagnosing Disease like Asthma: A Survey

“…"A new system of distributed computing tools" known as biomedical engineers envision have been developed that collectslegal medical data about patientsand stores itona secured network which gives a quick delivery and efficient care to patients. In order to obtain such benefits, the target population has to be monitored 24 hours a day, and a Wireless Body Sensor Network (WBSN) is deployed [5].…”
