IoT-enabled healthcare network with SDN

The exponential rate at which the devices are connected to the internet leads to the development of newly emerged technology called IoT. This advance that has come up with IoT needs a new network infrastructure. There are various applications of IoT one such application is healthcare. Making use of IoT in healthcare benefits not only patients but the administration staff and hospitals as well. Traditional network infrastructure lacks in implementing the high-level network policies and manual command-line interfaces and thus becoming a hurdle in IoT enabled healthcare networks, at this point SDN has come into action. With the help of SDN not only the manageability of the whole network has become easy but it also eliminates the manual command-line interface as well. By just a few clicks, you are able to manage the traffic flow from defined source to destination. This paper aims to provide the need for SDN in IoT healthcare applications. Various benefits, challenges, current ongoing research directions, along with the detailed architecture of both the technology are illustrated.
