The concept of energy-efficient networking has begun to spread in the past few years, gaining increasing popularity. Besides widespread sensitivity ecological issues, such interest also stems from economic needs, since both energy costs and electrical requirements telcos' Internet Service Providers' infrastructures around world show a continuously growing trend. In this respect, common opinion among researchers is that sole introduction low consumption silicon technologies may not be enough...
Recently, network operators around the world reported statistics of energy requirements and related carbon footprint, showing an alarming growing trend. Such high consumption can be mainly ascribed to networking equipment designed work at maximum capacity with almost constant dissipation, independent traffic load. However, recent developments green technologies suggest chance build future devices capable adapting their performance absorption meet actual workload operational requirements. In...
The envisioned 5G ecosystem will be composed of heterogeneous networks based on different technologies and communication means, including satellite networks. latter can help increase the capabilities terrestrial networks, especially in terms higher coverage, reliability, availability, contributing to achievement some KPIs. However, technological changes are not immediate. Many current proprietary hardware, which hinders integration with future as well adoption new protocols algorithms. On...
Summary The space environment is still challenging but becoming more and attractive for an increasing number of entities. In the second half 20th century, a huge amount funds was required to build satellites gain access space. Nowadays, it no longer so. advancement technologies allows producing very small hardware components able survive strict conditions outer Consequently, can be designed wide set missions keeping low design times, production costs, deployment costs. One widely used type...
ABSTRACT This paper is not a survey related to generic wireless sensor networks (WSNs), which have been largely treated in number of papers addressing more focused issues; rather, it specifically addresses architectural aspects WSNs some way connected with satellite link, topic that presents challenging interworking aspects. The main objective provide an overview the potential role segment future WSNs. In this perspective, requirements most meaningful WSN applications drawn and matched...
Decentralized dynamic (closed-loop) optimal control strategies are sought for a class of finite state Markov decision processes, characterized by the sharing common past after <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">k</tex> steps delay. The is considered over time horizon, and it shown that nonclassical programming procedure can be applied, based on existence sufficient statistic constant dimension. Finally, infinite horizon case briefly...
With the aim of controlling power consumption in metro/transport and core networks, we consider energy-aware devices able to reduce their energy requirements by adapting performance. In particular, focus on state-of-the-art packet processing engines, which generally represent most energy-consuming components network devices, are often composed a number parallel pipelines "divide conquer" incoming traffic load. Our goal is control both configuration way distribute flows among them. We propose...
In telecommunications networks, distributed power management across heterogeneous hardware requires a standardized representation of each system's capabilities to decouple high-level algorithms from specifics. The Green Abstraction Layer (GAL) provides this interface between and lower level representing the physical resources that directly exert energy actions in network.
Besides a more widespread sensitivity to ecological issues, the interest in energy-efficient network technologies springs from heavy and critical economical needs, since both energy cost electrical requirements show continuous growth, with an alarming trend over past years. In this contribution, we explore try evaluate feasibility impact of power management policies, able well suit heterogeneous set highly modular architectures, generally used for developing today's equipment. The proposed...
The constant evolution and expansion of the Internet Internet-related technologies has exposed limitations current networking infrastructures, which are represented by unsustainable power consumption low level scalability. In fact, these infrastructures still based on typical, ossified architecture TCP/IP paradigm. order to cope with Future requirements, recent contributions envisage an towards more programmable efficient paradigms. this respect, paper describes basic issues, technical...
Abstract A control architecture for resource allocation in satellite networks is proposed, along with the specification of performance indexes and strategies. The latter, besides being based on information traffic statistics network status, rely upon some knowledge fading conditions over channels. problem consists assignment, by a master station, total available bandwidth among earth stations presence different types. Traffic are assumed to measure continuously their signal fade level, but...
In the last few years, network "softwarization" is gaining increasing popularity to achieve dynamicity and flexibility. Cloud computing, as well new paradigms of software defined networking (SDN) functions virtualization (NFV), are supporting this evolution. However, need move services closer users guarantee low latency in service fruition on one hand, trend support personalization other, stimulating migration toward edge nodes (in so-called "fog computing" fashion). This target INPUT...
