Abstract The Internet of Things (IoT) is rapidly changing the way in which we engage with technology on a daily basis. The IoT paradigm enables low-resource devices to intercommunicate in a fully flexible and pervasive manner, and the data from these devices is used for decision-making in critical applications such as; traffic infrastructure, health-care and home security, to name but a few. Due to the scarce resources available in these IoT devices, being able to quantify the reliability of them is a critical function. This report presents a detailed evolution of the area of reliability measurement, followed by an in-depth review of the state-of-the-art for quantification of reliability in the IoT, revealing the many challenges associated with this task. From this in-depth review, a set of key research directions for IoT reliability is determined. Despite the critical nature of the research area, at this current moment, this study is the first detailed review available in the area of assessing IoT reliability.

1 Introduction Computing has been the fastest growing field of the last century. Computing systems now pervade the fabric of our everyday lives. We cannot make a purchase from a store, withdraw money from our bank accounts or visit a hospital without interacting with a computing system. Computing systems are now relied upon for many mission-critical systems, such as aircraft control systems, military systems and nuclear power plants. With the criticality of our computing systems in mind, it is vital that there are methods in place to ascertain the reliability of such systems. One of the fastest-growing fields within computing is the Internet of Things (IoT). The IoT is expected to grow to an immense size over the next number of years. In 2011 Cisco predicted that there would be 50 billion devices connected to the IoT by 2020 (Evans 2011). These huge claims have also triggered predictions of monetary investments reaching into the trillions by 2020 (Rayes and Salam 2016).

numbers suggest a truly rapid growth in IoT, there are still many research challenges which must be solved for IoT to become fully integrated into our day-to-day lives. These barriers include trust, security, interoperability, reliability, scalability, performance, availability and mobility (Al-Fuqaha et al. 2015; Wang 2018; Ahmed et al. 2017; Saini 2016). These areas represent significant research challenges that must be addressed if we are to allow IoT to become the ubiquito
