During the last few years, users ail over world have become more and accustomed to availability of broadband access. This has boosted use a wide variety both established recent multimedia applications. However, there are cases where it is too expensive for network providers serve community users. typically case in rural suburban areas, slow deployment (or no at all) traditional wired technologies access (e.g., cable modems, xDSL). In those cases, most promising opportunity rests with...

Born from a need for pure "pay-per-use" model and highly scalable platform, the "Serverless" paradigm emerged has potential to become dominant way of building cloud applications. Although it was originally designed environments, Serverless is finding its position in Edge Computing landscape, aiming bring computational resources closer data source. That is, crossing borders assess merits computing, whose principal partner will be Internet Things (IoT) This move sounds promising as brings...

The IEEE 802.16 is a standard for broadband wireless communication in metropolitan area networks (MAN). To meet the QoS requirements of multimedia applications, provides four different scheduling services: unsolicited grant service (UGS), real-time polling (rtPS), non-real-time (nrtPS), and Best Effort (BE). paper aimed at verifying, via simulation, effectiveness rtPS, nrtPS, BE (but UGS) managing traffic generated by data sources. Performance assessed an system working point-to-multipoint...

Telecommunications networks are undergoing major changes so as to meet the requirements of next generation users and services, which create a need for general revised architectural approach rather than series local incremental technology updates. This is especially manifest in mobile broadband wireless access, where traffic increase expected, mostly because video transmission cloud-based applications. The installation high number very small cells foreseen only practical way achieve demands....

Traffic demands in mobile networks are expected to grow substantially the next years, both terms of total traffic volume and bit-rate required by individual users. It is generally agreed that only possible solution overcome current limitations deploy very dense heterogeneous wireless networks, which we call DenseNets. However, simply scaling down existing orders magnitude, as fulfill forecasts, not because following constraints: i) bottleneck would shift from Radio Access Network (RAN)...

Computation offloading through stateless applications is gaining momentum thanks to the emergence of serverless frameworks with inherent scalability properties. However, adoption a framework in an edge computing system requires careful consideration keep its advantages unscathed. In cloud, micro-services are scaled automatically according demands, but this would incur significantly higher cost than data center and cannot be as fluid. This especially relevant scenarios where nodes spread...

Quantumnetworking is emerging as a new research area to explore the opportunities of interconnecting quantum systems through end-to-end entanglement qubits at geographical distance via repeaters. A promising architecture has been proposed in literature that decouples between adjacent nodes/repeaters from establishing paths by adopting time slotted approach. Within this model, we destructure further path establishment into two subproblems: selection and scheduling. The former set determine...

The evolution of quantum computing technologies has been advancing at a steady pace in the recent years, and current trend suggests that it will become available scale for commercial purposes near future. acceleration can be boosted by pooling compute infrastructures to either parallelize algorithm execution or solve bigger instances are not feasible on single computer, which requires an underlying Quantum Internet: interconnection computers links repeaters exchange entangled bits. However,...

In terms of the calibre and variety services offered to end users, smart city management is undergoing a dramatic transformation. The parties involved in delivering pervasive applications can now solve key issues big data value chain, including gathering, analysis, processing, storage, curation, real-world visualisation. This trend being driven by Industry 4.0, which calls for servitisation products across all industries, field cities, where people, sensors, technology work closely together....

As the field of quantum internet advances, necessity for a comprehensive guide to navigate its complexities has become increasingly crucial. Quantum computing, more established relative, shares foundational principles with internet; however, distinguishing between two is essential further development and deeper understanding. This work systematically introduces by addressing fundamental questions: Why it important? What are core components? How does function? When will be viable? Who key...

Abstract Given the diverse array of physical systems available for quantum computing and absence a well‐defined Internet protocol stack, design optimisation networking protocols remain largely unexplored. To address this, authors introduce an approach that facilitates establishment paths capable delivering end‐to‐end fidelity above specified threshold, without requiring detailed knowledge network's properties. In this study, define algorithms are specific instances evaluate them in...

The Network Simulator 2 (ns-2) is an open source tool for network simulation. When planning large-scale simulation experiments, efficient and flexible data collection a statistically sound output analysis are important aspects to keep in mind. Unfortunately, ns-2 offers little support collection, statistical of the results most often performed offline, using either home made code or available packages, which not integrated with ns-2. In this paper we describe two complementary contributions:...

Voice over IP (VoIP) is gaining an ever increasing popularity. As such, it nowadays represents one of the most studied test applications in performance evaluation wireline and wireless networks. However, a sound analysis VoIP communications should be carried out at user level, by computing perceptive metrics like Mean Opinion Score (MOS) or E-Model. In this paper, we present enhancements to popular Network Simulator 2 (ns-2) that allow reliable user-level through simulation. We show measures...

IEEE 802.16e specifies a connection-oriented centralized medium access control (MAC) protocol, based on time division multiple (TDMA), which adds mobility support to the MAC protocol defined by 802.16 standard for fixed broadband wireless access. To this end, orthogonal frequency (OFDMA) is specified as air interface. In OFDMA, frame extends over two dimensions: time, in units of OFDMA symbols, and frequency, logical sub-channels. The base station (BS) responsible allocating data into frames...

Serverless computing is becoming widely adopted among cloud providers, thus making increasingly popular the Function-as-a-Service (FaaS) programming model, where developers realize services by packaging sequences of stateless function calls. The current technologies are very well suited to data centers, but cannot provide equally good performance in decentralized environments, such as edge systems, which expected be typical for Internet Things (IoT) applications. In this paper, we fill gap...
