The process of transformation leading to a new generation operational and business support systems ensures effectiveness improvements while moving the organization towards a customer centric solution that provides a new wave of services in a multi-domain partner environment. This paper discusses the first steps of this transformational process for the research and educational networks.
Software-defined networking (SDN) overcomes many limitations of traditional networking architectures because of its programmable and flexible nature. Security applications, for instance, can dynamically reprogram a network to respond to ongoing threats in real time. However, the same flexibility also creates risk, since it can be used against the network. Current SDN architectures potentially allow...
Softwarization is a systemic trend which appears under several paradigms impacting networks, services and terminals evolution. Even the Internet of Things (IoT) scenario is going to be affected by this revolution. The efforts that are being made to provide IoT objects with embedded logic reconfiguration capabilities and the architectures that are being defined to support standard Machine-2-Machine...
With the increasing deployments of Network Functions Virtualization (NFV) in both industry and academia, it becomes necessary to design mechanisms for keeping the integrity of Service Function Chains (SFC) responsible for NFV services delivering. Despite the advances in the development of management and orchestration for NFV, solutions to keep SFCs resilient to well-known and zero-day threats are...
The Internet Of Things (IoT) is poised to make substantial inroads in all aspects of modern life before the end of this decade, including applications in smart grids, smart cities, transportation, crowdsensing, e-health, ambient assisted living, and home automation, to list just a few. Although it is recognized that IoTSec mechanisms and principles are needed across the entire IoT ecosystem, many...
It is the aim of IoT-Testware to supply a rich set of TTCN-3 test suites and test cases for IoT technologies to enable developers in setting up a comprehensive test environment of their own, if needed from the beginning of a project. Initially, IoT-Testware will focus on protocols like CoAP and MQTT. To ensure test and implementation technology independence, the test suites will be realized in TTCN-3...
Existing transistor-level monolithic 3D (T-M3D) standard cell layouts are based on the folding scheme, in which the pull-down network is simply folded and placed on top of the pull-up network. In this paper, we propose a new layout method, the stitching scheme, targeted towards improved cell performance and power integrity. We perform extensive analysis on each layout scheme and evaluate the timing/power...
Service Function Chaining (SFC) serves the traffic of a specific service along an ordered set of Service Functions (SFs). SFC uses Software Defined Networking (SDN) and Network Function Virtualization (NFV) technologies to reach the deployment and removal of SFC in an appropriate time with minimal costs. However, during the life time of deployed SFCs, the SFs are exposed to the risk of overloading,...
In this paper, a low power 4-bit 400 MS/s standard cell based flash Analog-to-Digital Converter (ADC) is presented. The proposed flash ADC uses comparators based on the logic gates. Relationship between the input voltage and comparator reference voltage defines the output of comparator to be '1' or '0'. The comparator is followed by the gain booster and encoder. Low power consumption is achieved by...
This paper proposes the different way of designing standard-cell based flash ADC in order to increase its input dynamic range. It includes implementation of 5-bit flash ADC for fully automated digital synthesis. The input dynamic range is increased by including 5-input logic gates. The proposed architecture results in Differential Non-Linearity (DNL) of ±0.206 LSB and Integral Non-Linearity (INL)...
In this paper, we propose and implement two electronic control unit (ECU) architectures for real-time automotive cyber-physical systems that incorporate security and dependability primitives with low resources and energy overhead. These ECUs architectures follow the multiprocessor system-on-chip (MPSoC) design paradigm wherein the ECUs have multiple heterogeneous processing engines with specific functionalities...
This letter presents a framework for the compressive acquisition of correlated signals. We propose an implementable sampling architecture for the acquisition of ensembles of correlated (lying in an a priori unknown subspace) signals at a sub-Nyquist rate. The sampling architecture acquires structured compressive samples of the signals after preprocessing them with easy-to-implement components. Quantitatively,...
Avionics systems, along with their internal hardware and software components interfaces, must be well defined and specified (e.g., unambiguous, complete, verifiable, consistent, and traceable specification). Such a specification is usually written in the form of an Interface Control Document (ICD), and represents the cornerstone of the avionics system integration activities. However, there is no commonly...
Programmable Logic Controllers (PLCs) are specialized computing systems for the control and monitoring of distributed industrial devices. Aiming for a highly connected industrial Internet-of-Things (IoT) ecosystem, PLCopen OPC Unified Architecture (UA) specification has been released. This paper presents the implementation and evaluation of a PLCopen OPC-UA software component for industrial control...
In this paper we explore how some parameters, less investigated in the literature, can be selected in a Histogram of oriented gradients (HOG)-based car detection system. The main goal is to find ways for reducing computation complexity while maintaining a good classification performance, in order to make possible real-time, embedded implementations. We analyze the effect of cell size, of binary representation...
Recent work has employed joint typicality encoding and decoding of nested linear code ensembles to generalize the compute-forward strategy to discrete memoryless multiple-access channels (MACs). An appealing feature of these nested linear code ensembles is that the coding strategies and error probability bounds are conceptually similar to classical techniques for random i.i.d. code ensembles. In this...
This work analyses the actual throughput of the Discrete Sine Transform (DST) stage in a realistic HEVC encoder, which executes the rate-distortion optimization algorithm to achieve high compression quality. Then, a low complexity DST factorization, where all the integer multiplications are substituted with add-and-shift operations, is exploited to design an efficient 1D-DST core. The proposed 1D-DST...
The Universal NUMber, or UNUM, is a variable length floating-point format conceived to substitute the current one defined in the IEEE 754 standard. UNUM is able, through an internal algebra based on interval arithmetic, to keep track of the precision during operations, offering better result reliability than IEEE 754. This work discusses the implementation of UNUM arithmetic and reports hardware implementation...
