Institute of Electrical and Electronics Engineers (IEEE) researchers are proposing changes both in the way haptic information is transmitted and received, and in leveraging 5G's multiplexing capabilities to enable near-real-time feedback without the high overhead of a Transmission Control Protocol approach or the unreliability of a system based on the User Datagram Protocol.
"A fundamental challenge in context of the Tactile Internet is the development of a standard haptic codecs family, similar to the state-of-the-art audio (ITU-T H.264) and video (ISO/IEC MPEG-4) codecs," the researchers note. "Embracing both kinesthetic as well as tactile information, such a codec family would be a key enabler for scalability at the network edge and universal uptake."
The researchers say the feasibility of a reliable haptic network is facilitated by 5G networks' versatility, specifically via the use of Network Function Virtualization and Software Defined Networking (SDN). The "network function can be managed as a software module that can be deployed in any standard cloud computing infrastructure," they report.
"On the other hand, SDN provides an architectural framework wherein control and data planes are decoupled, and enables direct programmability of network control through software-based controllers."
