Internet of Things (IoT) is a word used to designate an atmosphere where billions of objects are connected to the internet and are interacting independently. IoT is an innovative prototype providing novel set of services for the future technological inventions. Applications of IoT are unlimited with continuous addition of the cyber-world with the physical world. Smart healthcare system advancement and dissemination has become possible by the convergence of various IoT architectures. In specific, the IoT has been extensively useful to interconnect medical resources and deliver reliable, effective and smart healthcare services to the elderly and patients with a chronic illness. IoT changes the manner in which the facilities are conveyed to the healthcare industry. This paper presents major technologies in IoT-based smart healthcare services. It starts with introduction, definition of IoT, IoT enabling technologies in smart healthcare and IoT challenges in smart healthcare.
