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,…

Collision-free full-duplex UWB communication based on the Standard IEEE.802.15.4a
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Regarding these qualities, it is comprehensible that there is an interest in the automation industry to use ultra-wideband-based wireless sensor nodes to replace wired systems, to save energy and to save costs without reducing…
Parallel execution of AUTOSAR legacy applications on multicore ECUs with timed implicit communication
Parallelization of AUTOSAR legacy applications is a fundamental step to exploit the performance of multi-core ECUs (MCEs). However, the migration of an application from a single-core ECU (SCE) to a MCE presents two challenges: first, the extraction of parallelism from an application (composed of tasks) is not always possible due to communication among tasks. Second, reproducing the…
Electric field of grounded horizontal line transmitter for through-the-earth communication
An electrode-based through-the-earth (TTE) communication system sends its signal directly through the earth overburden of a mine by driving an AC current into the earth. The resultant current density is detected and communication is established. Given the noise level and the attenuation characteristics of the earth, the receiver sensitivity and transmitter power required for communication can be estimated. In an effort…
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…
Demonstrating a software defined network (SDN) using Carrier Ethernet Switch Routers in a provider network
We demonstrate SDN in a service provider network using adapted Carrier Ethernet Switch Routers developed based on principles of segment routing. SDN based service composition and delivery is showcased and validated.
Survivable virtual infrastructure mapping with dedicated protection in transport software-defined networks [Invited]
Efficiently mapping multiple virtual infrastructures (VIs) onto the same physical substrate with survivability is one of the fundamental challenges related to network virtualization in transport software-defined networks (T-SDNs). In this paper, we study the survivable VI mapping problem in T-SDNs with the objective of minimizing the VI request blocking probability. In particular, we address the subproblems of modulation selection and…
Toward control path high availability for software-defined networks
High Availability (HA) is one of the most critical requirements in real network operation. Provisioning redundancies, enabling failure detections and notifications, supporting a state synchronization, and invoking failure mitigation have been the essential steps to achieve the HA feature. Software-DefinedNetworking (SDN) is an emerging networking paradigm that centralizes the control plane by separating it from the data plane. In this paper,…
Rethinking virtual private networks in the software-defined era
Multi Protocol Label Switching (MPLS) Virtual Private Networks (VPNs) have seen an unparalleled increasing adoption in the last decade. Although their flexibility as transport technology and their effectiveness for traffic engineering are well recognized, VPNs are difficult to set up and manage, due to the complexity of configurations, to the number of involved protocols, and to the…
Software-defined transceivers for dynamic access networks
Software-defined transceivers are about to be established in long-haul optical communications. But will they be of equal importance in dynamic access networks? And which technology seems most promising?
