We propose Rogowski coils as coupling elements for Power Line Communication (PLC) in lithium-ion batteries for electric and hybrid vehicles. Current battery management systems use standard CAN busses for the communication between the battery control unit (BCU) and battery modules, which comprise lithium-ion cells. In contrast, in next-generation batteries the BCU should communicate with each lithium-ion cell in a…

A Compact Readout Electronics for the Ground Station of a Quantum Communication Satellite
Free-space quantum key distribution (QKD) is being developed for achieving unconditional securecommunication over ultra-long distance, which requires higher electronics performance, such as higher time measurement precision, higher data-transfer rate, and higher system integration density. As part of the ground station of the Quantum Science Satellite that will be launched in 2016, we specifically designed a compact…
Real-Time Communication for the Internet of Things Using jCoAP
The term Internet of Things (IoT) describes a scenario where embedded systems are integrated into everyday objects, turning them into smart devices to assist the user in his everyday life. Each of these smart objects only offers a very limited amount of computational power since it is only specialized in a limited set of tasks.…
LMMSE equalized DCSK communication system over a multipath fading channel with AWGN noise
The advances in the development of chaos based communication system suggests that chaos shift keying (CSK) and its variant Differential CSK (DCSK) are one of the most promising candidates for practical implementation. In this paper a DCSK communication system incorporating a non coherent approach of demodulation based on a correlation detector is considered over a…
A federated simulation toolkit for electric power grid and communication network co-simulation
This paper introduces a federated simulation toolkit (FSKIT) that couples continuous time and discrete event simula- tions (DES) to perform the co-simulation of electric power grids and communicationnetworks. A High Performance Computing (HPC) oriented power system dynamic simulator, GridDyn, was used for the electric power grid simulation. GridDyn is coupled to the open-source network simulator, ns-3,…
Modulation Classification of Single-Input Multiple-Output Signals Using Asynchronous Sensors
This paper discusses the automatic modulation classification of weak communication signals using distributed low-cost sensors. The concept of a secondary user in sensor networks is presented and very high-order statistics are used as modulation features. Two feature-based methods, single-variable and multivariable modulation classifiers, are proposed for estimating unknown modulation schemes through single-input multiple-output signal sensing channels. The…
DYWAMIT: Asynchronous Wideband Dynamic Spectrum Sensing and Access System
Dynamic spectrum access (DSA) is a promising solution for enhancing the utilization efficiency of spectrum resources. In DSA, spectrum sensing is crucial and cooperative spectrum sensing has been confirmed as a promising technology that can combat the wireless channel fading problem. Most current works have assumed that the secondary users (SUs) are synchronous with the…
Social Cognitive Heuristics for adaptive data dissemination in Opportunistic Networks
In typical Opportunistic Networking (OppNets) scenarios, mobile devices collaborate to cooperatively disseminate data toward interested nodes. However, the limited resources and knowledge available at each node, compared to possibly vast amounts of data to be delivered, makes it difficult to devise efficient dissemination schemes. Recent solutions propose to use data dissemination algorithms built on human information processing…
Towards a practical cognitive communication network for satellite systems
We present progress toward the formulation of a mathematical model for a cognitive communicationnetwork with applications to satellite systems. Our model employs abstract concepts including communicators, communications channels, and demand for capacity. These model elements may be tailored to represent a wide variety of practical communication scenarios. We present a dynamic automated reasoning methodology which uses the model…
A symbiotic resources sharing IoT platform in the smart cities context
Large urban areas are nowadays covered by millions of wireless devices, including not only cellular equipment carried by their inhabitants, but also several ubiquitous and pervasive platforms used to monitor and/or actuate on a variety of phenomena in the city area. Whereas the former are increasingly powerful devices equipped with advanced processors, large memory capacity,…
