An increase of vehicles in a city without an efficient infrastructure of traffic management can cause damages not only financial but also environmental and social. In order to support urban traffic system to relieve the traffic congestion and the damage caused by congestion of vehicles, in this paper, we propose a mechanism for Intelligent Transport Systems named FOg RoutE VEhiculaR (FOREVER), in...
We present a showcase of our SDN-inspired facility for the Internet of Things (IoT) — the CORAL (Cross-Layer Control of Data Flows) infrastructure. CORAL provides a hierarchy of network controllers that monitor network behaviour and adapts network protocol parameters on demand. It is built on top of rich network control abstractions and is hardware-independent. Our facility offloads protocol functionality...
We present our thoughts on the design of a novel hybrid system for detecting anomalous traffic in large-scale, policy-rich data networks. A key innovation in our approach is the combination of static configuration analysis and dynamic traffic analytics. More specifically, we will first develop abstractions and mathematical models to formally model the network and security configurations to statically...
In this paper, we propose a disaster-aware smart routing scheme for highly-available information storage systems. Our proposed scheme is based on the concept of Symbiotic Computing to recognize disaster status in Real Space, and provides appropriate routes form Digital Space dynamically. This realizes effective data transmission considering disaster situation and its time variation. We have designed...
Wireless sensor networks (WSN) play an important role in many applications like healthcare, traffic monitoring, security, environmental and infrastructure monitoring. When designing these applications for different domains like healthcare, traffic management or military intelligence, people face a lot of challenges. Service-oriented architecture (SOA) is an emerging area in distributed computing that...
In remotely deployed Wireless Sensor Networks (WSN) software faults may occur due to sensor nodes process failures. Fault diagnosis remains a challenging task due to physical inaccessibility of sensor nodes, energy constraints and varying application requirements for latency and reliability. WSN once deployed resort to fault management mechanisms to ensure continued operation. While fault detection...
Single controller implementation of SDN has many problems related to single points of failure, computational complexity growth, reliability and scalability. To solve these problems, multi-controller implementation of Software Defined Network has been introduced. Multiple controller implementation of the SDN control plane for large networks environment solves the scalability and reliability issues...
With the size and various applications of Internet growing, the structure and function of the network are becoming more and more complex, which makes it hard to be managed and controlled. The Internet has difficulty in providing QoS guarantees. Therefore, this paper proposes a controllable network architecture based on SDN[1]. In this architecture, "Q+ X" business guarantee mechanism is...
Underwater sensor networks (UWSN) transpires as a powerful technique in marine monitoring that includes various applications such as oceanographic data collection, marine surveillance and pollution detection. Localization in UWSN is very challenging as the sensor nodes are in a 3D space and are always in passive movement. Thus providing scalable and efficient energy aware routing services and localization...
Network-on-chip (NoC) has recently emerged as a primary paradigm for interconnecting ever increasing number of on-chip cores in future chip-multiprocessors (CMPs). As the advent of big data era, high volume of traffic injection, combined with the ever-changing patterns will exert severe pressure on some hotspots, leading to serious traffic congestion. These hot nodes will exhaust up the communication...
Networks-on-chip (NoCs) are already a common choice of communication infrastructure for complex systems-on-chip (SoCs) containing a large number of processing resources and with critical communication requirements. A NoC provides several advantages, such as higher scalability, efficient energy management, higher bandwidth and lower average latency, when compared to bus-based systems. Experiments with...
Software Defined Networking (SDN) and OpenFlow represent the most commonly deployed approaches of the so called Programmable Networks. SDN is an emerging network architecture, which performs the subdivision of control plane and data plane and allows greater speed, greater scalability, and greater ductility in terms of routing and forwarding. OpenFlow, instead, is an SDN component that characterizes...
Wireless Sensor Networks (WSN) are large systems that consist of low-cost, and resource-constrained sensor nodes. These networks are susceptible to many kinds of attacks as they have limited memory, battery life and computational power. Intrusion Detection is a solution to secure WSNs against several kinds of attacks. In this paper, we review types of attacks against WSNs and relevant intrusion detection...
The widespread deployment of Automatic Metering Infrastructures in Smart Grid scenarios rises great concerns about privacy preservation of user-related data, from which detailed information about customer's habits and behaviours can be deduced. Therefore, the users' individual measurements should be aggregated before being provided to External Entities such as utilities, grid managers and third parties...
With the shift towards cloud computing, application availability becomes a valid concern. Cloud applications have to be taken down to address various hardware and software problems. Even thoug redundancy insulates applications from hardware errors, the software updates and patches still require the service to be taken down for the period of the update. Organizations generally use lowactivity hours...
Three-dimensional integrated circuits (3D ICs) offer greater device integration, reduced signal delay and reduced interconnect power. It also provides greater design flexibility by allowing heterogeneous integration. However, 3D technology exacerbates the on-chip thermal issues and increases packaging and cooling costs. In order to exploit the intrinsic capability of reducing the wire length in 3D...
Traditional methods for implementing highly resilient systems are costly; and their methods using specialized hardware and high-speed interconnects do not extend to cloud. We demonstrate an architecture that rethinks the traditional approach and uses cloud's agility to provision additional capability as failures occur. This architecture continues serving requests with the best possible response...
Network virtualization is a viable solution to interconnect virtual resources providing isolation and to promote the architecture pluralism for the Future Internet. The virtualization causes an increase of complexity that could be handled by autonomic computing. We developed a multi-agent architecture for autonomic management of virtual networks in infrastructure providers. A prototype system focusing...
The emerging three-dimensional integrated circuits (3D ICs) offer a promising solution to mitigate the barriers of interconnect scaling in modern systems.

Besides its various advantages in terms of area, power consumption, and performance, this architecture has a unique...
Nowadays different sectors such as transport companies or public safety and emergency forces have great demand in mobile communications. In general, this area raises complex scenarios, where different access networks can be used, based on high-level administrative parameters (cost, geographic location). The use of different access networks could bring advantages in terms of availability and quality...
