Chapter 1 - A review on Internet of Multimedia Things (IoMT) routing protocols and quality of service

Abstract

An interconnected network of multimedia devices is known as the Internet of Multimedia Things (IoMT). The characteristic of IoT to produce scalar sensor data differentiates this from IoMT. The IoMT consists of tiny multimedia devices that require less energy consumption and real-time data delivery. IoMT requires many multimedia devices connected through a stable network, efficient routing protocol, and lightweight computation to achieve the objective. The suitable design of the routing protocol improves the performance of IoMT in many folds. The Internet Engineering Task Force (IETF) user working group has standardized the IPv6 routing protocol for low power and lossy networks (RPL). The RPL is ubiquitous for resource-constrained devices and perfectly suitable for IoMT. In IoMT, the significant issues with the routing protocols are a large number of heterogeneous devices, high bit error rate, frequent link breaks, assurance of the quality of service, and emission of CO2. In addition to the suitable traditional routing protocol of IoT, many green routing protocols, fault-tolerant routing protocols, context-aware, and energy harvesting-aware routing protocols are specially designed for IoMT. The efficient design of routing protocol and improved quality of service (QoS) widens the application spectrum of IoMT in intelligent environments. This chapter presents a comprehensive review of traditional and most recent routing protocols and QoS in IoMT. The design of these protocols successfully satisfies the current and future requirements of the IoMT network in terms of handling a large volume of data, heterogeneous data types, and energy issues.
