Due to development in advanced sensor technology, communication protocols,
and IT infrastructure, it is easy for health care service providers to deploy an
efficient and reliable wireless sensor network for providing quality services to their
consumers like patients, doctors, or medical consultants. This paper describes various
techniques of monitoring vital body parameters of a patient for diagnosing the
root cause using WSN. The authors have further described various challenges along with some suggestions
that can be used while implementing the WSN based patient monitoring system.
