Implementation of an Optical-Wireless Network with Spectrum Sensing and Dynamic Resource Allocation Using Optically Controlled Reconfigurable Antennas

This work proposes the concept and reports the implementation of an adaptive and cognitive radio over fiber architecture. It is aimed at dealing with the new demands for convergent networks by means of simultaneously providing the functionalities of multiband radiofrequency spectrum sensing, dynamic resource allocation, and centralized processing capability, as well as the use of optically controlled reconfigurable antennas and radio over fiber technology. The performance of this novel and innovative architecture has been evaluated in a geographically distributed optical-wireless network under real conditions and for different fiber lengths. Experimental results demonstrate reach extension of more than 40 times and an enhancement of more than 30 dB in the carrier to interference plus noise ratio parameter.

A conceptual-driven survey on future internet requirements, technologies, and challenges

Nowadays, research initiatives to redesign the Internet are popping up around the world. Each of these projects has a particular focus and its own set of design requirements and key technologies. The panorama shows a wide diversity of pre-requirements and arguments, some very specific and superficial, others more general and deep. Despite this diversity, a conceptual-driven analysis of such scenario could reveal the current state-of-the-art on future Internet research, the common aspects that permeate all initiatives, and the open issues to be addressed in future work. This paper provides a comprehensive overview of the contemporary research from an abstract point of view, covering the design requirements and ingredients that are being adopted, interrelating, and analyzing them.

Cognitive radio in the context of internet of things using a novel future internet architecture called NovaGenesis

For the first time, we present a convergence among cognitive radio network (CRN), IoT and a future Internet architecture proposal.We present the concept of a low-cost embedded cooperative sensing and cognitive radio architecture for IoT applications.We have experimentally demonstrated that the use of cooperative spectrum sensing based on energy detection has overcome the problem known as hidden node.The proposed radio approach has been integrated to a future Internet proposal called NovaGenesis, which has been previously developed by our research group.We demonstrated novelties on distributed naming resolution for hosts, operating systems, services, and data objects using natural language names and self-verifying names. Display Omitted Many Internet of Things (IoT) requirements are already at the core of next generation wireless networks, including 5G, cognitive radio and future Internet. There is a huge consilience that the majority of Internet devices will become sensors and actuators equipped over ordinary things. As a consequence, the radio environment will increasingly become crowded with thousands of low-cost devices sharing the unlicensed frequency bands. This paper is regarding a convergent solution of future Internet and cognitive radio in the context of IoT. It proposes an embedded and low cost cooperative spectrum sensing solution, which has been experimentally implemented. Furthermore, we present a distributed software-controlled sector aware spectrum sensing architecture to store and analyze the spectrum usage information. Finally, the proposed approach has been integrated to a future Internet architecture called NovaGenesis. A proof-of-concept has been experimentally performed, demonstrating for the first time the convergence of IoT, future Internet and cognitive radio.

Searching for Synergies among Future Internet Ingredients

Currently, there are many proposals to redesign the Internet. While some design ingredients are common to several approaches, the way they are adopted and combined usually differs from proposal to proposal. This paper defends the argument that a deeper architectural rethinking requires a deeper search for synergies among the selected ingredients. It argues that this is fundamentally a possible path to simplify the design, since ingredients are homogenized towards more coherent blueprints. The paper explores raised synergies in a conceptual way and proposes some guidelines to help designing accordingly.

Developing NovaGenesis architecture for internet of things services: Observation, challenges and ITMS application

A new concept of Internet technology is fast emerging within the Internet domain as a successful extension to it has now knows to become Internet of Things (IoT). The concept of wireless devices with embedded systems has paved the way for improved Intelligent Systems in the field of IoT. Intelligent Systems life cycle has begun with the advancements in development of IoT. However, the vision of application development on the platform of IoT is still in nascent stages. Our visualization of IoT as billions of “things” connected to each other under normal, as well as smart “things”, will be used in every sphere of our lives. High rise in recorded traffic density, road accidents, and crisis faced in regulating effective management of traffic control in rural areas have concerned us to develop a smart solution in context to Intelligent Traffic Management Systems (ITMS). We adopted this architecture and framework to provide the adequate ecosystem for the design and development of ITMS, which has the capability to overcome the challenges of transportation management system.

Semantic edge computing and IoT architecture for military health services in battlefield

In this paper, we are visualizing a military health service (MHS) platform which is based on hierarchical IoT architecture. We propose a semantic Edge based network model which plays a significant role for communicating tactical and non-tactical piece of information over the network. Further, the exchange of information and subsequent data analysis on the MHS makes the system intelligent and smart. In any standard battlefield scenario, there is a command and control center that correlates the events happening in real time. We have made this command and control center as semantic edge component. This center is entrusted with making vital decisions on the tactical arena of the battlefield. The main aim of the proposed architecture is to provide secured zone to monitor soldiers health and their weapons conditions, respectively. We have also introduced the semantic edge computing mechanism to deal with the large amount of health data in terms of processing, storing and sharing information.

Towards an Opportunistic, Socially-driven, Self-organizing, Cloud Networking Architecture with NovaGenesis

The exponential growth on the number of mobile devices and their capabilities are leveraging new possibilities of networking architectures for processing, storing, and exchanging of information. At a glance, existing architectures take advantage of these devices, the social behavior of their users, and/or the dynamicity on resource usage. Despite of the potential of existing initiatives, they do not interoperate which reduce their applications and deployment. As we walk towards a very dynamic world (regarding the user needs and characteristics, the information traversing the network, and the networking capability to adapt), these architectures should merge into a solution that fits any type of scenario. In this paper, we specify an opportunistic, socially-driven, selforganizing, cloud networking architecture using a future Internet proposal named NovaGenesis. We highlight the requirements and solutions that NovaGenesis brings in to accommodate the inherent challenges of today’s dynamic networking scenario, describing a convergent architecture, which integrates the new requirements with the already implemented NovaGenesis features.

Developing a NovaGenesis architecture model for service oriented future Internet and IoT: An advanced transportation system scenario

We are designing a NovaGenesis Architecture Model to support Future Internet services, which are going to address some fundamental issues of the Internet of Things, such as address resolution, mobility, routing, scalability, security, and network control. The aim is to support trillion of things connect to the Internet. In NovaGenesis, we have presented a set of distributed systems where any information processing is seen as service. Services organize themselves based on names and agreements to meet semantics rich goals, policies, regulations, etc. Even networking functionalities are considered as services. Every existence could have one or more names: natural language names or self-certifying names. All the communication, processing, and storage are name-oriented. The protocol stacks are built on demand in a contract-based way. Hence, we can state that NovaGenesis architecture could be an alternative solution for current internet oriented innovations in a scalable manner. The aim of this architecture is the coverage of Internet and sensors oriented smart objects. The paper discusses the proposed model in the context of an Advanced Rural Transportation System.

Internet of Information and Services: A Conceptual Architecture for Integrating Services and Contents on the Future Internet

Worldwide, dozens of projects to redesign the Internet are in progress under the banner of the so-called Future Internet research. Some proposals argue that the most important thing is to design to accommodate information exchanging, a.k.a. information-centrism. Others argue that the most important thing is to design to accommodate service-based applications. In this paper, we defend the idea that the most important thing is to design to integrate both aspects in a cohesive way. To do so, architectural blueprints should be able to solve indirections generally, to allow mobility and semantic rich search for services and contents, as well as location, hiring and dynamic invocation of services. In this paper, we propose a single conceptual architecture capable of integrating the service- and information-centric approaches for the Future Internet. We call this approach as Internet of Information and Services (IoIS).

Future Network Architectures: Technological Challenges and Trends

The Internet became an extraordinary artifact for information exchanging, and it is now being considered a strategic infrastructure even for countries development. However, its success has fueled an upward spiral of new applications, which require increasingly intensive use of its capabilities, putting a lot of pressure on a design originally drawn for a scenario remarkably different from the current one. Concerned with actual Internet evolution and its limitations towards a future global information infrastructure, many research initiatives started to reinvent or rethink Internet, so it can fully assume the role we are assigning to it. This text discusses technological requirements, challenges and trends towards future network architectures. It covers latest new Internet design approaches and their main innovations.
