1.9.1 Diverse Communication Requirements for Different Industrial Use Cases
ОглавлениеAs we discussed in Section 1.3, the requirements of wireless industrial Internet for various types of applications widely vary in terms of energy efficiency, deployment complexity, latency, and MAC protocols. Many wireless technologies, standards, and protocols are used in IIoT and smart manufacturing systems, and managing their coexistence in a system is still an open question. For instance, deterministic transmissions are highly important in control, process, and operation systems and should be guaranteed in coexistence with various wireless networking technologies. Additionally, issues arise due to the nature of wireless medium such as limited spectrum, shared bandwidth, reliable durability, and availability.
Altogether, E2E communication is highly challenging in industrial environment, and it highlights the necessity for management and optimization of wireless networks in Industry 4.0. The main objectives of network management for wireless industrial Internet are (1) real-time and dynamic wireless network optimization and management to offer flexible communication; (2) network resource allocation at different levels of system (equipment, production, operation and enterprise planning levels) to ensure required QoS; and (3) monitoring workflows to improve a network’s visibility and performance.
