It is a network of ubiquitous devices or things that are capable of computation and communication over the Internet. One of the major applications of IoT is in the field of health care and related services. In the modern health care environment, IoT is being used in various medical areas like real- time monitoring, patient information management, medical emergency management and blood information management. Over these years a number of advanced applications based on IoT have been proposed for convenience of patients, doctors and caregivers in the healthcare sector. The IoT revolution is redesigning modern health care with promising technological, economic, and social prospects. This paper surveys the latest IoT based health care technologies and applications, and reviews the working and underlying architectures. The paper also discusses the major issues and challenges faced by them, leading to new insights and research directions in IoT. The main objective of this article is to help researchers in developing much more advanced and efficient IoT based healthcare applications. Keywords- challenges; healthcare; Internet of Things, issues; real time monitoring; survey; I. INTRODUCTION Internet of Things (IoT) [1-5] is the internetwork of physical objects or "things" that are embedded with software and sensors to collect and send data between them and central severs with no or minimum human intervention. IoT helps in remotely controlling and accessing these things along an existing infrastructure. This creates opportunity for integration of the physical world and the computer-based systems, which results in improved efficiency, accuracy and economic benefit. "Things," could be anything which has a physical existence, ranging from a very small object like a nano chip to large sized building. These things are embedded with sensors, actuators and sophisticated software which enable them to send and receive data. IoT is an emerging technology which has a wide variety of applications. As per statistics it was found that number of connected devices is increasing exponentially in since past few decades. It is said that by 2020, number of connected devices will exceed the total world population. This increase in number of connected devices points at the importance of Internet of Things in our daily life. In the next five years IoT will be the field of technology where most investment will be done because of its revolutionary growth rate. Over these years a number of advanced healthcare applications [6-10] based on IoT have been proposed for convenience of patients, doctors and caregivers. IoT when implemented in healthcare applications help to improve features of the existing healthcare systems by providing real- time monitoring patient information management, medical emergency management, blood information management and other facilities, thus increasing the quality of healthcare applications. There are different mobile applications and wearable devices which let patients to capture their health data. Hospitals also use IoT to provide real time health care facilities and to keep track of their patients and personnel. Some of the IoT healthcare applications used to monitor different health aspects includes blood pressure monitoring, blood glucose monitoring, heart functioning, monitoring physical fitness etc. Figure 1. IoT Network Internet of Things has the potential to accurately track people, equipment, specimens, supplies, or even service animals and analyze the data captured. A number of applications combining with ad hoc networks [11-16] and sensor networks [17-18] have been developed with Internet of things to assist patients and doctors in many important services. With patients attached to sensors to measure vital signs and other biometric information, problems could be more rapidly diagnosed, a better quality of care given, and resources used more. There are exciting applications of the IoT for healthcare International Journal of Computer Science and Information Security (IJCSIS), Vol. 15, No. 1, January 2017 248 https://sites.google.com/site/ijcsis/ ISSN 1947-5500
