The ever-increasing demand of mobile Internet traffic is pushing operators to look for solutions increase the available bandwidth per user and unit area. At same time, they need reduce load in core network at a reasonable cost their future 5G deployments. Today's trend points deployment extremely dense networks order provide ubiquitous connectivity high data rates. However, this hard couple with current networks' architecture, which heavily centralized, posing difficult challenges when...
5G requires a redesign of transport networks in order to feed the increasingly bandwidth hungry radio access and benefit from performance/cost efficiency provided by integration both backhaul fronthaul segments over same substrate as well incorporation cloud RAN architectures. In addition, increase its usage cost efficiency, this new network should allow simultaneous use different tenants (e.g. MVNOs, OTTs, vertical industries). This article presents architecture designed 5G-Crosshaul...
Cloud-based robotics systems leverage a wide range of Information Technologies (IT) to offer tangible benefits like cost reduction, powerful computational capabilities, data offloading, etc.However, the centralized nature cloud computing is not well-suited for multitude Operational (OT) nowadays used in that require strict real-time guarantees and security.Edge fog are complementary approaches aim at mitigating some these challenges by providing capabilities closer users.The goal this work...
Multi-access edge computing (MEC) technologies bring important improvements in terms of network bandwidth, latency, and use context information critical for services like multimedia streaming, augmented, virtual reality. In future deployments, operators will need to decide how many MEC points presence (PoPs) are needed where deploy them, also considering the number base stations support expected traffic. This paper presents an application inhomogeneous Poisson point processes with hard-core...
Edge computing and network slicing might be considered as the main pillars of upcoming 5G systems they inject flexibility into management operations. While one prominent architectural framework for edge has been recently defined by ETSI standard organization, namely multi-access (MEC), reached its momentum fostering interest in different standardization bodies fora. To better understand how such distinct definitions impact standardized MEC framework, published a study on matter. In this...
5G transport networks will need to accommodate a wide spectrum of services on top the same physical infrastructure and network slicing is seen as suitable candidate for providing necessary quality service (QoS). Traffic differentiation usually enforced at border in order ensure proper forwarding traffic according its class through backbone. With slicing, may now traverse many slice edges where policy needs be enforced, discriminated ensured, tenants needs. The goal this article hence analyze...
The IEEE 802.11aa Task Group has recently standardized a set of mechanisms to efficiently support video multicasting, namely, the Addressed Transmission Service (GATS). In this article, we report implementation these over commodity hardware, which make publicly available, and conduct study assess their performance under variety real-life scenarios. To best our knowledge, is first experimental assessment GATS, performed along three axes: complexity in terms lines code, effectiveness when...
Next-generation mobile networks are expected to flaunt highly (if not fully) automated management. To achieve such a vision, Artificial Intelligence (AI) and Machine Learning (ML) techniques will be key enablers craft the required intelligence for networking, i.e., Network (NI), empowering myriad of orchestrators controllers across network domains. In this paper, we elaborate on DAEMON architectural model, which proposes introducing NI Orchestration layer effective end-to-end coordination...
An increasing number of systems span from the data-center down to micro-controller and need smoothly operate across this continuum composed by extremely heterogeneous network technologies computing platforms. Building these is quite challenging due limitations existing technological stacks. This paper introduces Zenoh a Pub/Sub-/Query protocol that unifies data at rest, in motion computations. has been designed ground-up address needs cloud continuum. It minimal wire overhead 5 bytes, it...
Data-flow programming is the computational model of choice for a large class application domains, such as, real-time data processing, robotics platforms, and big-data analytics. Traditionally, dataflows are deployed executed within well-defined system boundaries, as robots, radars, or data-centers. These boundaries however expected to blur with advent Edge Computing, which provides multi-tier infrastructure spanning from cloud things enables distribution applications across this continuum....
Cloud robotics aims at endowing robot systems with powerful capabilities by leveraging the computing resources available in Cloud. To that end, infrastructure consolidates services and information among robots, enabling a degree of centralization which has potential to improve operations. Despite being very promising, presents two critical issues: (i) it is hard control network between robots (e.g., long delays, high jitter), (ii) local context on access network) not This makes achieve...
Next-generation mobile networks will largely benefit from advances in softwarization and cloudification of network functions. However, fully exploiting the new potential flexible architectures front increasingly demanding service volumes requirements calls for an extremely effective integration Network Intelligence (NI) solutions into production infrastructures. While current standardization efforts towards embedding NI beyond-5G 6G systems are still their infancy, DAEMON project is...
Pushing contents, applications, and network functions closer to end users is necessary cope with the huge data volume low latency required in future 5G networks. Edge fog frameworks have emerged recently address this challenge. Whilst edge framework was more infrastructure-focused mobile operator-oriented, pervasive included any node (stationary or mobile), including terminal devices. This article analyzes opportunities challenges integrate, federate, jointly orchestrate resources into a...
The fifth generation (5G) of mobile communications introduces improvements on many fronts when compared to its previous generations. Besides the performance enhancements and new advances in radio technologies, it also integrates other technological domains, such as cloud-to-things continuum artificial intelligence.

Fog computing has rapidly become a widely accepted paradigm to mitigate cloud computing-based infrastructure limitations such as scarcity of bandwidth, large latency, security, and privacy issues. resources applications dynamically vary at run-time, they are highly distributed, mobile, appear-disappear any time over the internet. Therefore, ensure quality service experience for end-users, it is necessary comply with comprehensive monitoring approach. However, volatility dynamism...
The complexity of orchestrating Beyond 5G services, such as vehicular, demands novel approaches to remove limitations existing techniques, these might cause a large delay in orchestration operations, and thus, negatively impact the service performance. For instance, human-in-the-loop approach is slow prone errors, closed loop control using rule-based algorithms difficult design, an abundant number parameters need be configured. Applying Artificial Intelligence (Al)/Machine Learning (ML),...
In this paper, we describe the design, implementation, and evaluation of Bologna, a practical block-based IEEE 802.11 data transmission recovery protocol. Bologna is built on well-known scheme that identifies corrupted bit blocks by performing per-block checksums then requests retransmission only error blocks. The two key challenges for design are (1) to find proper checksum which strong enough detection meanwhile lightweight in computation communication overhead, (2) modify standard as...
