Abstract

As two-way communication services based on the direct realtime interaction with users emerge, the techniques to reduce the end-to-end delay are crucial to realize the tactile internet. To this end, cut-through switching that allows data forwarding during its receiving process has attracted much attention. Motivated by it, we develop a flexible transmission scheme aiming to reduce the end-to-end packet delay. We redesign the frame structure and implement it on a software defined radio (SDR) based system. We evaluate the performance of the proposed scheme through experiments on a testbed.
