Push-Based Critical Data Forwarding Mechanism for IoT in Healthcare Using Named Node Networking

摘要

Recently Internet of Things (IoT)-based healthcare systems have facilitated remote healthcare monitoring services which offer enormous benefits over the customary healthcare monitoring systems. Healthcare IoT can provide access to services anytime and everywhere. This is particularly beneficial for those who suffer from chronic diseases and thus require regular monitoring. However, forwarding critical information regarding a patient’s body, such as blood pressure, heart rate, body temperature etc., in a prompt manner to the healthcare server and caregiver units without waiting for someone to fetch the data is still the main problem. Along with this, exchange of IoT data over host-centric networks, which are different in many aspects compared to IoT networks, has many drawbacks and vulnerabilities which represent yet more problems. To solve these problems, this paper proposes an efficient push-based critical data forwarding approach for IoT in healthcare, considering a content-centric communication infrastructure. We use named node networking, which is an Information Centric Network (ICN)-based architecture, with two new completely independent namespaces for proof of our concept. We compare our proposal with Name Data Networking (NDN). The simulation results and performance evaluation showed the feasibility and efficiency of our proposed architecture.
