WBAN for Health Monitoring
A WBAN for health monitoring consists of many sensor nodes that can measure and report the user’s health state continuously. These sensor nodes are employed on the human body. The exact connected and location of the sensor nodes on the human body depend on the sensor type, size, and weight. Sensors can be worn as stand-alone devices or can be assembled into costume jewelry, applied as tiny patches on the skin, hidden in the user’s clothes, shoes or glasses, or even implanted in the patient’s body [23]. The exact number and type of the sensors used in a WBAN for health monitoring depend on the end user application and may include a subset of the following sensors:

• An ECG sensor for checking heart movement
• An

World Wide Web). The nodes can be static or dynamic [24]. Wireless Sensor Networks (WSN) will continue to play a very important role in our day to day lives. A WSN contains of sensor nodes that are powered by little unique batteries. These sensor nodes are densely arranged in the area to be monitored to sense and transmit information towards the base station. WSN can simplify structure design and operation, as the environment being monitored does not need the communication or energy infrastructure connected with wired networks [25].
A sensor network consists of a large number of sensor nodes, which are arranged either inside the phenomenon to be monitored or very close to it. Sensor networks denote an important improvement over traditional sensor networks, which are deployed in two means as shown below [26]:

a. Sensors can be placed far from the actual phenomenon to be monitored. With this approach, huge sensors that use some complex systems to differentiate the targets from environmental noise are required.

b. Several sensors that perform only sensing can be deployed. Careful thoughts are put into the design of the positions of the sensors and communications network topology. They diffuse time series of information about the phenomenon to central nodes where computations are performed and records are fused.
There are limitations on a wireless sensor network, such as power consumption, lifetime,
