Query: Pervasive Healthcare-A Comprehensive Survey of Tools and Techniques   Pervasive healthcare is an emerging technology that aims to provide
round-the-clock monitoring of several vital signs of patients using various
health sensors, specialized communication protocols, and intelligent
context-aware applications. Pervasive healthcare applications proactively
contact the caregiver provided any abnormality arises in the health condition
of a monitored patient. It has been a boon to the patients suffering from
different diseases and requiring continuous monitoring and care, such as,
disabled individuals, elderly and weak persons living alone, children of
different ages, and adults who are susceptible to near-fatal falls or sudden
increases in blood pressure, heart rates, stress level, etc. Existing surveys
on pervasive healthcare cover generic techniques or a particular application,
like fall detection. In this paper, we carry out a comprehensive coverage of
several common disorders addressed by pervasive healthcare in recent years. We
roughly classify different diseases by age groups of patients and then discuss
various hardware and software tools and techniques to detect or treat them. We
have also included detailed tabular classification of a large selection of
significant research articles in pervasive healthcare.
