“…The major drawbacks of a mm-wave RoF system are that, as the RF frequency increases, so does the requirement of sophisticated DL optical transmitters at the CS (NE2) [43][44][45][46][47][48], efficient topologies for the ODN (NE7) [49][50][51][52][53], and low-cost and "green" UL transmitter configurations at the BS (NE14) [54][55][56][57]. Thus, the proposed framework considers these NEs as key network elements (KNEs).…”

“…A complete analysis of network topologies for RoF systems is presented in [50]. Several topologies options such as star, ring, multilevel rings, multilevel stars, hybrid multilevel starrings, and ring-stars are compared in terms of link distance, reliability and availability of the network.…”

“…DL and UL transmitter's references and technical details can be found in an extensive survey that we presented in [84]. For ODN topology (NE7), the framework considers 13 topologies divided in single (star, ring, bus) and multilevel (stars, rings, and hybrid combinations) schemes as presented in [50]. This knowledge base supports more than 3500 different network architectures when combining available technologies for NE2, NE7, and NE14.…”

“…The component cost and power consumption data for the transmitters are obtained from component manufacturers datasheets as in [91]. The reliability values were calculated from several literature references [50,92,93]. On the other hand, for the network topology, the assessment is performed considering TBS and network coverage.…”

This paper presents the research work involved in the development of a knowledge-based framework for the design of millimeter-wave 60 GHz radio over fiber (RoF) land networks. It combines object-oriented, rule-based, technical information, and procedural functions to support engineers in the conceptual and preliminary design of a network. The overall framework is organized in two main modules: the first module is a tutorial of the terminology and basic principles in the design of RoF networks. The second module is a design assistant system that requests input data from the user about the functional network requirements and its prioritized figures of merit. The proposed design assistant is capable of providing support on the major activities of the 60 GHz RoF land network design such as downlink and uplink channel assignment and network clustering, wavelength allocation, optical link design, and network integration. The assistant is user interactive through the implementation of a graphical user interface. To illustrate the validation of such framework, we present a case of study of a network design with specific requirements.

“…Optical wireless communications (e.g. radio-over-fiber (ROF) access networks), on the other hand, has been also widely researched [3][4][5]. Since it's combining the advantages of optical wire/wireless communication systems, providing a very promising transport platform due its high mobility connections and its large bandwidth [6,7].…”

While remote zone 3 protection relays are essential to power systems, their false trips are also one of main causes related to cascading blackouts. Although many methods have been developed on traditional power systems to address this issue, the past cascading failure events showed the ineffectiveness of these methods.With the development of Smart Grid (SG), new agent-based methods have been proposed to address this issue by utilizing SG real-time communications. We found that these solutions simply assume ideal communication networks and do not consider the effect of practical network constraints and resource management. In this paper, we propose several solutions to address practical network resource management and constraints, and further improve the agent-based solutions in order to prevent the false tripping of zone 3 relays in various conditions. We also analyze the potential issues of these solutions, and point out the future investigation in this direction.
