This paper proposes a novel distributed asynchronous multi-channel MAC scheme for large-scale Vehicular Ad Hoc Networks, namely, Asynchronous Multi-Channel MACDistributed (AMCMAC-D). The proposed scheme supports simultaneous transmissions on different service channels, while allowing rendezvous and broadcast of emergency messages on the control channel. The(More)
This paper provides an in-depth view of Terahertz Band (0.1–10 THz) communication, which is envisioned as a key technology to satisfy the increasing demand for higher speed wireless communication. THz Band communication will alleviate the spectrum scarcity and capacity limitations of current wireless systems, and enable new applications both in classical(More)
This paper proposes an analytical model for the throughput of the enhanced distributed channel access (EDCA) mechanism in the IEEE 802.11p medium-access control (MAC) sublayer. Features in EDCA such as different contention windows (CW) and arbitration interframe space (AIFS) for each access category (AC) and internal collisions are taken into account. The(More)
Terahertz (0.06–10 THz) Band communication is envisioned as a key technology for satisfying the increasing demand for ultra-high-speed wireless links. In this paper, first, a unified multi-ray channel model in the THz Band is developed based on ray tracing techniques, which incorporates the propagation models for the line-of-sight, reflected, scattered, and(More)

As an industry customer of electric power, an electrical arc furnace (EAF) is a major flicker source that causes major power quality problems. For a 40-MVA EAF in Tennessee, USA, a cascade-multilevel converter (CMC)-based STATic synchronous COMpensator (STATCOM) with high bandwidth is proposed for EAF flicker mitigation. In this paper, flicker mitigation(More)
Terahertz band communication is envisioned as a key technology to satisfy the increasing demand for ultra-high-speed wireless links. In this paper, a multi-wideband waveform design for the THz band is proposed, by exploiting the channel peculiarities including the distance-varying spectral windows, the delay spread and the temporal broadening effects. This(More)
As an industry customer of utility, electrical arc furnace (EAF), acting as a varying and reactive power sink, is the major flicker source to influence the grid power quality. In this paper, based on the field data recorded at the electric system surrounding EAF, the flicker issues and reactive power compensation requirement are quantitatively analyzed. The(More)
