Abstract—Today Wireless Sensor Networks
technology has become very popular and showing its remarkable advantages in
medical area. In medical healthcare, WSN are considered as a key research area.
Here we have categorized the
sensor networks for healthcare system which are: Collection of long-term
databases of clinical data, Monitoring of patients in clinical settings, Home
& elderly care center monitoring for chronic and elderly patients. Through
which we can easily observe the patient condition either the patient is present
in clinic or at home. In critical situation we can also take care of patient as
well as easily find out the doctors any kind of medical help by using
telemonitoring and tracking application of WSN.
In this paper, we have
discussed about some WSN technologies which are using nowadays and proving that
how much their existence is helpfull for living a long life. i.e.AICOs,
HipGuard, ultra badge system, iPackage and CodeBlue etc. These are some those
technologies which are playing a very important role in our daily life and
making our life easier and better inspite of in the presence of many dangerous diseases.
In the near future, we will
see the vast implementation and discoveries of WSN in medical healthcare area.

An Emerging technology of wireless sensor
networks consists of small, low- cost and low- power devices. In WSN, generally
integrate limited computation, radio communication and sensing capabilities which
we can easily use in medical healthcare. WSN devices can be used to capture
continuous, real-time vital signs from a large number of patients, radiate the
data to handheld computers carried by nurses, physicians and emergency medical
WSN technology would enable medics to more effectively
care for large numbers of casualties in an disaster or emergency scenario.
Wearable sensor nodes can collect patient data such as
treatments, identification, and history, supplementing the use of paper charts
and back-end storage systems. First responders could receive instant
notifications on any changes in patient situation, such as cardiac arrest or
respiratory failure. Wearable systems for continuous health monitoring are a
key technology in helping the transition to more affordable and proactive
healthcare. Wearable health monitoring systems allow a personal to
considerately monitor changes in patient vital signs and provide feedback to
help maintain an optimal health status.
WSN approach has clear benefits for patient care but
raises challenges in terms of complexity and reliability in presence of mass
casualty event (MCE), For MCE, These networks can greatly reform the ability of
first responders to triage and treat multiple patients equipped with wearable
WSN are also referred as wireless medical sensor
networks (WMSNs), when they are designed for medical applications or used in
