Unprecedentedly, a massive number of devices are getting connected to the network in the new era of the Internet of Things. For the discovery, authentication,, secure access and management of these Internet of Things devices, an Internet of Things directory service is needed. Its responsibility would be to store and provide the attributes of Internet of Things devices, such as identifier, location,...
chapter
In this paper, we propose a mechanism for autoconfiguration of name-bound virtual networks (NBVNs) for Internet of Things (IoT). Some IoT standardization groups have defined APIs for IoT device communications, in which they indicate the correspondent nodes and resources by names. However, current technologies for the construction of Virtual Networks (VNs) rely on VLANs, IP routing, and OpenFlow control,...

We propose a novel IoT directory service for storing, updating, and providing records of mobile IoT devices or objects. The IoT directory service is designed to manage a massive number of records (about one billion) and support fast lookup (latency of less than 10ms). It performs proactive caching of the records in various replicas (following the movement of mobile IoT devices or application clients)...

The infrastructure that supports the digital world is adopting network and system virtualization to raise its reliability and flexibility. However, the allocation of such virtual resources is still performed by human administrators, which limits the agility of such systems to respond to events and new requirements. In this paper we propose an architecture that exploits the capabilities offered by...

Unprecedentedly a massive number of devices are getting connected in the coming era of the Internet of Things (IoT). For discovery, remote access and management of these IoT devices, an IoT directory service is needed to store and provide their various attributes such as location, generated data types, owner's name, and security keys. In this paper, we present the architectural design of the IoT directory...

IoT heterogeneity and diversity have promoted the creation of different and isolated IoT systems. The EU has funded several research projects in order to promote interoperability and quality aspects for IoT platforms. More significantly, the IoT-ARM was conceived as a reference architecture to derive concrete IoT platforms and establish a common understanding on quality requirements between different...

The raise of Software Defined Networking (SDN) opens a wide spectrum of improvements for network architectures targeting different problems. It includes the case of those architectures designed to overcome mobility and multi-homing problems in big networks, such as the Internet, as is the case of the HIMALIS network architecture. In this paper we present an approach for HIMALIS to benefit from SDN...

The Internet is continuously evolving from a static, host-based, uniquely attached node model to a mobile, host-free node model with the possibility of multiple attachment points to the network. However, the current Internet was not designed to support this type of workload because of its strict addressing mechanism. Thus, the Future Internet promotes the introduction of new architectures that provide...

There are more and more scenarios requiring the transparent integration of heterogeneous security services in order to facilitate application development, simplify deployment and provide a seamless user experience. One of the most common use cases occurs when resources make use of OAuth to provide a simple and flexible way to authorize clients in order to access protected resources. But different...

In this paper we discuss the experimentation results we obtained from performing video streaming in Internet of Things (IoT) scenarios built on top of Content Centric Networking (CCN) architecture. More precisely, we used the Dynamic Adaptive Streaming over HTTP (DASH) mechanism to split videos into multiple pieces, also offering multiple bit-rates. Such pieces are then streamed by a DASH client from...

The discovery of network objects (content, services, devices, persons, etc.) is an important challenge to face when researching towards the Future Internet. In this paper we give an overview of the challenge regarding network object discovery for the Future Internet, proposing a new architecture that provides mechanisms to achieve network object discovery from partial object descriptions, building...
chapter
Internet of Things (IoT) is presenting an enormous growing, in numbers, it is estimated that over 50 billion of devices will be connected to Internet by 2020. Therefore, it presents a high scalability requirement to manage every resource connected to the network. Therefore, It is required a high capability for autonomous registration and discovery of resources and services. In addition, it should...
chapter
The rising of the Internet of Thing has imposed new challenges for the Future Internet to cover the specific requirements in terms of simplicity, low-power, and addressing flexibility. In this paper we present an architecture that allows network elements (things) to reach each other in terms of their identities instead of addresses or flat labels. Thus, the network entities are addressed in a natural...
chapter
The GEMBus framework is intended to provide the necessary mechanisms to build federated composite services. Thus, it can constitute a key element in achieving cross-stratum optimization by combining network-layer events with service-layer operation knowledge. Taking advantage of the unique service perspective of the high level network operations we can use the GEMBus framework to compose the services...
chapter
In this paper we discuss an approach to build a secure and scalable network interconnection mechanism based on a gateway overlay network for address-less, identifier-based networks. The purpose of the overlay network is twofold. First, it provides a mapping between end-node identifiers and gateway identifiers. Second, it is the mechanism used to deliver messages from one network to another. As the...

In this paper we show how to bring enhanced privacy to future content delivery network architectures, with special attention to Content-Centric Networking (CCN). This objective is primarily achieved through the prevention of operation traceability while raising the role of communication parties to be a central element of the network. Thus, we propose an identity-based architecture that provides these...

There are many projects in the search for Future Internet (FI), supported by many countries and with different fundamental targets. This paper is centered around the HIMALIS architecture proposed as part of the AKARI project by the NICT of Japan. We describe this architecture and discuss its research and experimentation capabilities, finally showing its behavior in a scenario with heterogeneous underlying...
chapter
The basic idea behind the locator/identifier separation in network protocols is to differentiate the location (where) from the entity (who) that is taking part in the communication. But the architectures following this idea are finally associating an entity with the particular device it is using to communicate, which means that actual identity behind the device is not considered enough and that its...
chapter
In the present paper we discuss the concepts on which is based the GEMBus framework, a multi-domain, federated Enterprise Service Bus. Then, we show certain production scenarios as general use-cases, and a brief analysis of the selected platforms for the basis of the framework. Furthermore, we discuss the role that Autonomic Computing (AC) services play on the framework, showing a representative scenario...
chapter
In this paper we show a service-oriented architecture for managing network systems and services without human intervention, ensuring compliance with rules and policies set by administrators. Furthermore, we show the evaluation results of a proof-of-concept implementation of the architecture running in a test environment where it has to manage the links that connects the main router of an organization...
