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,…

Full-duplex MAC protocol based on adaptive contention window for visible light communication
As an alternative technology to radio-frequency-based communication, visible light communication(VLC) has attracted tremendous interest from both academia and industry. For its medium access control (MAC) protocol, most existing design has focused on the half-duplex mode, which can be inefficient for two-way communications. In this paper, we propose a novel full-duplex MAC protocol for VLC networks. Different from half-duplex…
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…
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…
Active probing assisted monitoring for software defined networks
Efficient and agile control-plane design is crucial for emerging flexible, on-demand optical networks. Active probing assisted monitoring is proposed and shown to reduce monitoring time by around 75% to achieve rapid monitoring in optical networks.
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…
Customizable Autonomic Network Management: Integrating Autonomic Network Management and Software-Defined Networking
The increased complexity of emerging and future networks and services requires the use of sophisticated but simplified management and control that will minimize the burden of human presence and manual operation. Autonomic network management (ANM), on the one hand, and software definednetworking (SDN), on the other hand, have appeared with the promise to meet these requirements and enhance the efficiency of 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?
Route optimization for DASH over Software Defined Networks
In this paper, a method for the selection of the paths between the server and the clients for Dynamic Adaptive HTTP Streaming (DASH) over Software Defined Networks (SDN). In the proposed method, an optimization model is presented for increasing the Quality of Experience (QoE) in the clients by increasing the average received bitrates and for providing fairness by decreasing…
Software defined network traffic measurement: Current trends and challenges
Next generation networks such as Software Defined Networks (SDN) must support the integration of new paradigms of service offerings such as virtual cloud computing, big data applications, data centers services, and rich multimedia content. Operators of next generation SDNs are responsible for configuring policies that employ traffic monitoring tools and measurement mechanisms to detect and react to a wide range of network events…
