Editing Wireless sensor network (section)

===Health care monitoring===
There are several types of sensor networks for medical applications: implanted, wearable, and environment-embedded. Implantable medical devices are those that are inserted inside the human body. [[Wearable technology|Wearable]] devices are used on the body surface of a human or just at close proximity of the user. Environment-embedded systems employ sensors contained in the environment. Possible applications include body position measurement, location of persons, overall monitoring of ill patients in hospitals and at home. Devices embedded in the environment track the physical state of a person for continuous health diagnosis, using as input the data from a network of [[depth camera]]s, a [[sensing floor]], or other similar devices. Body-area networks can collect information about an individual's health, fitness, and energy expenditure.<ref>{{Cite journal | last1 = Peiris | first1 = V. | doi = 10.1117/2.1201312.005120 | title = Highly integrated wireless sensing for body area network applications | journal = SPIE Newsroom | year = 2013 }}</ref><ref>{{cite conference | url=https://www.ucc.ie/en/media/research/misl/2009publications/pervasive09.pdf | title=A Context Aware Wireless Body Area Network (BAN) | author=Tony O'Donovan | author2=John O'Donoghue | author3=Cormac Sreenan | author4=David Sammon | author5=Philip O'Reilly | author6=Kieran A.

Especially due to the integration of sensor networks, with IoT, the user authentication becomes more challenging; however, a solution is presented in recent work.<ref>{{cite journal|author=Bilal, Muhammad|display-authors=etal|title=An Authentication Protocol for Future Sensor Networks|journal=Sensors|volume=17|issue=5|page=979|doi=10.3390/s17050979|pmid=28452937|pmc=5464775|year=2017|bibcode=2017Senso..17..979B|arxiv=1705.00764|doi-access=free}}</ref>
