PROJECT TITLE :

Experimental Demonstration of Delay-Bounded Wireless Network Based on Precise Time Synchronization

ABSTRACT:

In wireless communications of the fifth generation (5G) and beyond, low latency and reliable information transfer are two features that are in high demand. Carrier Sense Multiple Access with Arbitration Point (CSMA/AP) is a novel delay-bounded wireless media access control (MAC) protocol that was developed to strictly ensure the upper boundary of communication delay. CSMA/AP is also known as Carrier Sense Multiple Access with Arbitration Point. With a straightforward arbitration mechanism that takes advantage of the accurate timing synchronization provided by Wireless Two-Way Interferometry, CSMA/AP makes it possible to have communications that are both collision-free and delay-bounded (Wi-Wi). Before any further discussion of CSMA/AP and its extension to a variety of applications can take place, one of the most important steps that must be completed is the experimental demonstration, which includes proving the feasibility of the system in wireless environments. Constructing a star-topology wireless network with software-defined radio terminals and precise time synchronization devices allowed us to experimentally demonstrate the fundamental principles of CSMA/AP, which are described in this paper. In this work, which is described in this paper, we carried out this work. We demonstrate that CSMA/AP was successfully operated even though there were dynamic shifts in the spatial position of the terminal or the capability to accommodate mobility. This was made possible by Wi-ability Wi's to real-time adapt to an environment that was constantly shifting. In addition, through the use of experiments, we were able to demonstrate that the proposed CSMA/AP principle cannot be implemented without the use of Wi-Fi, which demonstrates the significance of maintaining accurate time synchronization. This study paves the way toward the realization of delay-bounded wireless communications, which will be necessary for the development of low-latency and highly reliable critical applications in the future.
