Limited scalability, reliability, and security of todays utility communication infrastructures are main obstacles to the deployment of smart grid applications. The C-DAX project aims at providing and investigating a communication middleware for smart grids to address these problems, applying the information-centric networking and publish/subscribe paradigm. We briefly describe the C-DAX architecture, and extend it with a flexible resilience concept,…

The relationship between cultural dimensions and the quality of communication in education
Culture is the collective programming of the mind distinguishing members of one group or category of people from others [1]. Each culture is different. Therefore, there are five dimensions of culture and this article explains and explores one of these: Power Distance (PD). This paper will outline the impact of these dimensions in educational institutions.…
Photonic Crystal Waveguide Sources of Photons for Quantum Communication Applications
Reliable sources of photons will be required to develop many photonic quantum technologies. Current on-demand sources are lacking in brightness, compactness, and scalability. Here, we review the use of silicon photonic crystal waveguides as nonlinear photon generators in the 1550 nm band. We show that these photon sources can create strong frequency correlations, that the…
Implementation of fault tolerant control for modular multilevel converter using EtherCAT communication
Modular Multilevel Converter (MMC) is very promising technology this days. It offers fault tolerant capabilities and ensures high efficiency with low output voltage harmonic content which results in need for smaller filter size. A disadvantage of the system is that the control becomes more cumbersome due to the high number of the employed submodules. A…
SBVLC: Secure Barcode-based Visible Light Communication for Smartphones
2D barcodes have enjoyed a significant penetration rate in mobile applications. This is largely due to the extremely low barrier to adoption – almost every camera-enabled smartphone can scan 2D barcodes. As an alternative to NFC technology, 2D barcodes have been increasingly used for security-sensitive mobile applications including mobile payments and personal identification. However, the…
Exact Capacity of Amplify-and-Forward Relayed Optical Wireless Communication SystemsExact Capacity of Amplify-and-Forward Relayed Optical Wireless Communication Systems
In this letter, we model a dual-hop subcarrier intensity modulated amplify-and-forward (AF) relayed optical wireless communication system with the assumption that direct communication between source and destination is not feasible. The optical channels are considered to be impaired with path loss, misalignment errors, and atmospheric turbulence, and are modeled assuming independent but not necessarily identically distributed Gamma-Gamma fading statistics.…
Evaluation of Vehicle-to-Vehicle Communication with Delay Tolerant Networks for Safety Surveillance System
Recently, the rapid technological growth of automobiles expects us to the various usages for the near future, and V2V communication is also a part of novel technologies to realize novel usages as well as ITS. This paper proposes the V2V communication with Delay Tolerant Networks (DTN) for safety surveillance system in the local area during the winter season. In…
Distributed traffic simulation using DDS-communication based HLA for V2X
For implementing Cooperative Intelligent Transport Systems (C-ITS), Vehicle-to-X (V2X)communication functions are important. For efficient V2X simulation, integrating heterogeneous simulators and sophisticated inter-simulator network control are required. In this paper, we suggest Data Distribution Service (DDS) communication-based High Level Architecture (HLA) for distributed V2X simulation by replacing HLA network transport into DDS-based communication. For replacing, we design HLA-DDS wrapper…
Control-plane slicing methods in multi-tenant software defined networks
In this paper, we focused on two prevailing architectural approaches for control-plane virtualization in multi-tenant OpenFlow-ready SDN domains: The first permits the delegation of a specific, non-overlapping part of the overall flowspace to each tenant OpenFlow controller, exposing him/her the entire substrate topology; the second conceals the substrate topology to tenants by abstracting resources and…
Software defined network for multi-tenancy resource sharing in backhaul networks
This paper introduces a Software Defined Network (SDN) architecture for 5G dense multi-infrastructure provider deployed wireless backhaul networks. The architecture contains a two-tier controller in a hierarchical setup aiming to offload some of the control functionalities from the central controller to a collection of logically distributed dynamically configured local controllers in order to balance the tradeoff between scalability and system…
