  Recent advancement in the wireless sensor networks has provided a platform to
numerous applications in healthcare sector. It has become an active research
area due to its large scale potential. This research focuses on the application
areas of wireless sensor networks specifically in the healthcare sector. In
this work, we have tried to explain the different challenges faced by the WSNs
in order to implement them. The different pros and cons of the WSNs in
healthcare sector are also discussed. Some important parameters which can be
used to evaluate the performance of the wireless sensor networks are also
presented in this work. Wireless sensor networks have a tremendous future and
it should be taken at its earliest because of the significant importance of the
healthcare issues.
