The Future internet will integrate large-scale systems constructed from the composition of thousands of distributed services, while interacting directly with the physical world via sensors and actuators, which compose the internet of Things. This Future internet will enable the realization of the Smart Cities vision, in which the urban infrastructure will be used to its fullest extent to offer a better quality of life for its citizens. Key to the efficient and effective realization of Smart Cities is the scientific and technological research covering the multiple layers that make up the internet. This paper discusses the research challenges and initiatives related to Future internet and Smart Cities in the scope of the InterSCity project. The challenges and initiatives are organized in three fronts: (1) networking and High-performance Distributed Computing; (2) Software Engineering for the Future internet; and (3) Analysis and Mathematical Modeling for the Future internet and Smart Cities. InterSCity aims at developing an integrated open-source platform containing all the major building blocks for the development of robust, integrated, sophisticated applications for the smart cities of the future.

This paper deals with usage of single-chip computers for collection of data and control. The aim is to design a general control system, which is easy to use and easy to implement for other laboratory tasks. performance of control system is limited by performance of used MCU (PIC 16F873A) and its peripherals (2xPWM, 5xA/D...). Main task of MCU are communication with upper level and implementation of required control action together with data collection. Communication between control system (IPC) and MCUs is provided by serial interface. In the first step control system defines initialization of MCU (reset needed) for desired laboratory task then continues with the control application. Everything is controlled and monitored from SCADA/HMI system called control Web. Application is accessible via internet browser in local network.

The rise of the internet of Things and the growth of the IP cameras market are making Wireless Video Sensor networks (WVSNs) popular. In turn, Wi-Fi is becoming the enabling technology for WVSNs due to its flexibility, high bitrates provided and low cost; however, these networks suffer from three major problems: bad performance, throughput unfairness, and energy inefficiency. In order to address the lack of holistic solutions to solve these problems, we propose the FM-WiFIX+ solution. This solution uses FM radio as an out-of-band control channel to signal when a video sensor should turn its IEEE 802.11 interface OFF, thus saving energy. The results obtained with a proof-of-concept prototype show that for a network with 7 nodes the proposed solution can achieve gains of energy up to 48 %, while maintaining good levels of performance and throughput fairness.

internet of Things (IoT) promises to be a key enabler in Smart Manufacturing and Smart Supply Chain. The IoT systems are responsible for enabling and improving the operational efficiencies of factories, plant floors, including assembly plants. These systems are characterized by reliable sensing and reporting of multiple parameters within the factory floor. Such sensing activities offer safe, efficient and optimized performance of not only the machines manufacturing the products, but also the workforce operating them. Industrial IoT (IIoT) systems could suffer from high and uneven energy consumption due to the nature of the network deployment. Such behavior is unacceptable as it not only increases the carbon footprint of the plant, but also makes the planned maintenance of IoT devices for battery replacement a huge challenge. In this paper, we propose a heuristic and opportunistic link selection algorithm, HOLA, which not only reduces the overall energy consumption of the IoT network but also balances it across the network. HOLA achieves this energy-efficiency by opportunistically offloading the IoT device data to smart-devices being carried by the workforce in the factory settings. Further, these smart-devices with multiple radio links such as Bluetooth, Wi-Fi, and 3G/4G LTE heuristically determine the best link to transmit the data to the Cloud based on the quality and energy cost of the link. Our experimental and simulation studies validate that HOLA can improve the energy efficiency of IIoT systems by reducing the overall energy consumption and balancing it across the network.

In this paper, a QoS-aware traffic classification framework for software defined networks is proposed. Instead of identifying specific applications in most of the previous work of traffic classification, our approach classifies the network traffic into different classes according to the QoS requirements, which provide the crucial information to enable the fine-grained and QoS-aware traffic engineering. The proposed framework is fully located in the networkcontroller so that the real-time, adaptive, and accurate traffic classification can be realized by exploiting the superior computation capacity, the global visibility, and the inherent programmability of the networkcontroller. More specifically, the proposed framework jointly exploits deep packet inspection (DPI) and semi-supervised machine learning so that accurate traffic classification can be realized, while requiring minimal communications between the networkcontroller and the SDN switches. Based on the real internet data set, the simulation results show the proposed classification framework can provide good performance in terms of classification accuracy and communication costs.

Software Defined networking (SDN) and internet of Things (IoT) integration has thrown many critical challenges. Specifically, in heterogeneous SDN-IoT ecosystem, optimized resources utilization and effective management at the control layer is very difficult. This mainly affects the application specific quality of Service (QoS) and energy consumption of the IoT network. Motivated from this, we propose a new Resource Management (RM) method at the control layer, in distributed SDN-IoT networks. This paper starts with reasons that why at control layer RM is more complex in the SDN-IoT ecosystem. After-that, we highlight motivated examples that necessitate to investigate new RM methods in SDN-IoT context. Further, we propose a novel method to compute controller performance. Theoretical analysis is conducted to prove that the proposed method is better than the existing methods.

The main issue for electric power operators is power quality of the network. Voltage stability is the biggest challenge facing electric power operators, especially in distribution side. It contributes more than 80% of issues concerned with power quality problems. Locally, the Egyptian national grid is suffering serious problems due to the gradual increase of load demand, which causes the power system to be unstable, and exposed to voltage instability problems. This paper investigates the impact of D-STATCOM on the performance of a realistic electrical network of a new city in Upper Egypt. The study is performed using NEPLAN commercial software. The selected network consists of 20-buses along with 20 distribution transformers of 22/0.4 kV and two medium voltage distribution points (DP). This network is studied with and without D-STATCOM to show the impact of D-STATCOM on the networkperformance regarding to voltage stability, control of voltage magnitude, and reduction of total active power losses.

Software Defined networking (SDN) is an emerging paradigm that allows network operators to have more control of their infrastructure. control is achieved by decoupling control and data plane of the network. controller is the place where all the intelligence of SDN resides; hence it is important to test the capabilities of the controller before deploying it in production networks. This paper presents an analysis of the capabilities of two open-source python based OpenFlow SDN controllers (POX and RYU). The analyzed indexes include performance of both the controllers when subjected to layer 1 and layer 2 switching. For testing purposes Mininet emulator and Distributed-internet Traffic Generator (D-ITG) traffic generator are used. The results of the evaluation, when layer 1 switching is in question, show, that POX has better traffic handling capabilities, and, as a result, a better performance. But, as far as layer 2 switching is concerned, RYU came up with far better performance results.
