This study discusses a Time-Division Multiple Access (TDMA)-based multiple machine control system using power line communication (PLC). Because of the non-stationary features of the PLC channel, each TDMA slot has a different error rate. The variation of the slot quality causes the variation and degradation of the control performance of each machine. This manuscript thus proposes a new transmission...
This paper proposes a joint coding scheme for information advertisement in wireless mesh networks. Random network coding is a technique that can mitigate the effect of a broadcast storm problem. However, it cannot correct bit errors, and it should forward more and more packets to recover bit errors. On the other hand, multi-route coding was proposed to reduce bit errors on wireless channels. This...
This paper introduces a Visible Light Communication (VLC) system using an LED sign panel, which allows the provision of broadcast-type information in public spaces. This system provides an additional function to an LED advertisement panel; the panel not only displays an advertisement, but also transmits wirelessly to other devices. We suggest its use in benefit of the visually impaired. They can obtain...
