The 5G standard will be largely defined by directly integrating Internet of Things (IoT) and Industrial Internet of Things (IIoT) devices into global networks and devices. Researchers seeking to influence 5G technology are focusing on how to properly integrate this new type of computing into the mobile network ecosystem.
The growing interest in smart manufacturing technologies such as Cyber-Physical Systems (CPS) reveals the driving forces behind the trend of creating wireless standards that meet the needs of IIoT devices. The development of Cyber-Physical Systems, driven by wireless connectivity, is one example of a system enhanced through 5G standards and technologies.
Some of the main challenges these researchers face are related to the factors that define the internet, such as openness, connectivity, and flexibility. Another challenge includes the need to configure low-power wireless network protocols for remote deployments.
Here are some examples of how researchers are addressing challenges in IIoT technology, including how to achieve robust security, energy-efficient caching, and accuracy and reliability in portable medical devices within open networks.
Software-defined networks with attribute-based encryption
Network infrastructure based on Transmission Control/Internet Protocol (TCP/IP) cannot provide security standards suitable for smart grid technologies, as is the case in the medical and energy sectors. Therefore, researchers at the Thapar Institute of Engineering and Technology have created a secure network solution to address this issue.
Based on the conceptual design of software-defined networks, researchers proposed a communication model specifically for IIoT technologies by using a cuckoo filter to achieve efficient packet forwarding. They also outlined an attribute-based encryption scheme supported by the peer-to-peer entity authentication protocol Kerberos, which utilizes third-party authentication.
Researchers claim that the proposed solution offers better security without sacrificing performance compared to existing strategies.
Smartphone-driven biosensing dongle
Researchers from the University of Electronic Science and Technology of China have developed a prototype portable dongle for measuring blood sugar and uric acid levels. The device's creators explain that it is powered by the user's smartphone, which can share the measured bioinformatics with the user's doctor for health monitoring.
This device is comparable to similar health monitoring devices currently available in terms of accuracy and reliability. Compared to existing standards, which are primarily for large machines used in clinical settings, the device's greatest appeal lies in its portability.
While IIoT technology can be applied to many fields, previous network protocols have not adequately addressed various limitations. Some applications have unique requirements regarding security, energy efficiency, and portability.
These developments are examples of how IIoT technology is influencing the design of next-generation mobile communication protocols and the development of these standards.
