Abstract
The Internet of Things (IoT) is a vital component of many future industries. By intelligent integration of sensors, wireless communications, computing techniques, and data analytics, IoT can increase productivity and efficiency of industries. Reliability of data transmission is key to realize several applications offered by IoT. In this paper, we present an overview of future IoT applications, and their major communication requirements. We provide a brief survey of recent work in four major areas of reliable IoT including resource allocation, latency management, security, and reliability metrics. Finally, we highlight some of the important challenges for reliable IoT related to machine learning techniques, 6G communications and blockchain based security that need further investigation and discuss related future directions.

Summary
The Internet of Things (IoT) is one of the important technologies of this era that can add automation and smartness in several sectors such as transportation, health care, industries, agriculture, energy, and infotainment It works by deploying sensors on different devices used in these sectors, allowing the measurement of important real-time data. Efficient data transmission is a key challenge to ensure reliable IoT applications This means that data are transmitted at a high data rate such that latency is within the QoS requirement. We first present a discussion on massive IoT and its application requirements This is followed by four major use cases of the IoT and categorize the reliability related IoT work into four major units, i.e., resource allocation, latency management, security and reliability metrics. We present challenges that still need to be addressed to realize a reliable IoT network
