Internet of Things for Health Care

The Internet of things makes smart objects the ultimate buildings blocks in the development of cyber-physical smart pervasive frameworks. The IoT revolution is redesigning modern health care with promising technological, economic and social prospects. This paper surveys advances in IoT based health care solutions.In addition,this paper analyses distinct IoT security and privacy features, including security requirements, threat models and attack taxonomies from the health care perspective. Further this paper proposes an intelligent collaborative security model to minimize security risk. The proposed hierarchical approach clusters the documents based on the minimum relevance threshold. The results show that with a sharp increase of documents in the data set. The search time of the proposed method increases exponentially. Furthermore, the proposed method has advantage over the traditional method in the rank privacy and relevance of retrieved documents.IEEE 802.11 standardization for wireless connectivity is gaining popularity day by day because of its low cost solutions and ease of deployment for providing ubiquitous end- user connectivity. In an IEEE 802.11‘Wireless Fidelity’ (Wi-Fi) network, mobile users can connect to the Internet through wireless access points (APs) that form a backbone network through the wired distribution system. IEEE 802.11 Wi-Fi technology is widely used to provide public wireless connectivity at airports, restaurants and other such public places, known as ‘Wi-Fi Hot Spots’. The modern era of ‘wireless divide’ is gradually witnessing deployments of more advanced wireless technologies, such as IEEE 802.16 or Worldwide Interoperability for Microwave Access (Wi-Max). Wi-Max provides longer coverage area compared to Wi-Fi Technology through advanced modulation and coding schemes for signal transmissions. WiFi-WiMax integration is research topic for next generation wireless Internet architecture and ‘Internet of Things’(IoT) designs that attract significant attentions among the researchers. The recent developments in WiFi-WiMAX integration The current mobile communication system, especially voice communication system is so very well acquainted with the GSM system that it would seem hard to introduce path breaking changes into the way the GSM networks are run. GSM networks use radio frequency (RF) based carriers for mobile communication. The heavy dependency on RF is not only causing severe bandwidth crisis but is also exerting a tremendous pressure on the existing energy generation units. With the number of mobile subscribers increasing exponentially and IoT (Internet of Things) connected devices storming into the market, there is a need for a huge bandwidth that will support all the systems. Visible light communication (VLC) has been proved to be an effective alternative that will prevent the impending crisis. In the past few years, many researchers have come up with VLC based solutions as alternatives to RF in mobile networks. But all of them deal with using VLC in an internet based networking scenario, especially indoor communication. This paper are expected to be useful for researchers,engineers,health professionals and policy makers working in the area of the IoT and health care technologies and also it provides detailed research activities concerning how the IoT can address pediatric and elderly care chronic disease ,private health and fitness management.
