Cloudlet Softwarization for Pervasive Healthcare

Patient monitoring is emerging as an important application of embedded sensors network. Many wireless sensors are implanted in/on the patient body. These tiny wireless sensors make Wireless Body Area Networks (WBANs). WBANs can observe physiological conditions of patient under supervision, and can provide us real-time feedback. Through WBAN a patient is constantly monitored, and in case of some critical situation an immediate action should be required. In today's world most of the healthcare organizations need to modernize their IT infrastructure so that they can be able to provide safer, faster and more efficient healthcare delivery. This paper presents a new architecture based on cloudlet and software defined networking to smooth out devices and access networks heterogeneities and enable fast access for data collection and analysis through the cloud environments.
