Throughout the world there is in huge developing crises with respect to healthcare workforce shortages, as well as a growing burden of chronic diseases. As a result, e-health has become one of the fastest-growing service areas in the medical sector. E-health supports and ensures the availability of proper healthcare services, public health, and health education services at a distance and for remote places. In order for the sector to grow and meet the need, e-health applications has become one of the fastest growing area of research, but to grow at a larger scale it requires the following:

1) The availability of use cases for exact identification of problems that need to be visualized.

2) A well-supported market that can promote and adopt the e-health care concept.

3) Development of cost-effectiveness applications and technologies for successful implementation of e-health at a larger scale.
