The explosive growth in the usage of IEEE 802.11 network has resulted in dense deployments in diverse environments. Most recently, the IEEE working group has triggered the IEEE 802.11ax project, which aims to amend the ...
A passive wake-up radio in a wireless sensor network (WSN) has the advantage of increasing network lifetime by using a wake-up radio receiver (WuRx) to eliminate unnecessary idle listening. A sensor node equipped with a ...
Some of the challenges faced by network service providers stem from early design and implementation decisions made at the infancy of data communications. Due to its groundbreaking potential, the Internet exploded from a ...
The NFV is focused at virtualizing network functions such as gateways, path computing devices, resource allocation mechanisms, proxies, firewalls and transcoders, traditionally carried out by specialized hardware devices, ...
Today’s data center networks such as Fat-tree and BCube, are over-provisioned for multi-path routing; and they suffer from inefficient power usage when traffic is not heavy. Green routing technologies are effective approaches ...
New software-defined open network concepts are proposed in this paper to enable an efficient implementation of front- and backhaul solutions for future 5G mobile networks. Main requirements for 5G front- and backhaul are ...
In this paper, we describe the basics of the Recursive InterNetwork Architecture (RINA) and its advantages as a packet transport technology over programmable optical networks. In particular, its seamless integration over ...
The EU funded FP7 project T-NOVA, with the specific goal of accelerating the evolution of NFV, proposes an open architecture to provide Virtual Network Functions as a Service (VNFaaS), together with a dynamic, and flexible ...
The Internet of Things (IoT) intends to interconnect massive amount of heterogeneous, smart devices, with the goal of interweaving the virtual world with the physical world. Smart Cities are typical IoT application domains, ...
In this paper we introduce a novel reliable asynchronous protocol that allows to establish a VLC link between a LED luminary and an off-the- shelf smartphone. Our protocol and decoding algorithms benefit from the access ...
Cities increasingly face challenges related to pollution, efficient use of resources (e.g. water, energy) and ensuring a good quality of life for its citizens. Solutions built on existing and emerging technologies such as ...
The use of Visible Light Communication (VLC) in wake-up communication systems is a potential energy-efficient and low-cost solution for wireless communication of consumer electronics. In this paper, we go one step further ...
The popularity and wider acceptance of IEEE 802.11 based WLANs has resulted in their dense deployments in diverse environments. While this massive deployment can potentially increase capacity and coverage, the current ...
The Recursive InterNetwork Architecture (RINA) is a general architecture for all forms of computer networking, based on a single type of programmable layer that recurs as many times as required by the network designer. The ...
Current Internet security is complex, expensive and ineffective. The usual argument is that the TCP/IP protocol suite was not designed having security in mind and security mechanisms have been added as add-ons or separate ...
RINA, the Recursive InterNetwork Architecture, is a novel “back to basics” type approach to networking. The recursive nature of RINA calls for radically different approaches to how networking is performed. It shows great ...
5G networks aims to tackle the complex demands of emerging business paradigms, such as Smart Cities, eHealth, and Industry 4.0. In this paper, a hierarchical, distributed intelligence 5G architecture is described, offering ...
In this manuscript, we present the main concepts of the 5G-PPP SESAME project dedicated to the implementation of Cloud-Enabled Small Cells (CESCs), able to support edge cloud computing in a multi-tenant, multi-service ...
In this paper we study the benefits of applying Software Defined Networking (SDN) to control forwarding in a network of constrained wireless edge devices. The proposed architecture is applicable to dense Small Cell deployments ...
