Both long shorter term approaches considered, as well both wide-area multiple-area networks parts of network. results in paper were developed frame research project DAVID (Data And Voice Integration over DWDM) project, funded by European Commission through IST-framework.
Abstract The range of applications wireless sensor networks is so wide that it tends to invade our every day life. In the future, a network will survey health, home, roads we follow, office or industry work in even aircrafts use, an attempt enhance safety. However, themselves are prone security attacks. list attacks, although already very long, continues augment impeding expansion these networks. trust management schemes consist powerful tool for detection unexpected node behaviours (either...
The digitization of manufacturing industry has led to leaner and more efficient production, under the Industry 4.0 concept. Nowadays, datasets collected from shop floor assets information technology (IT) systems are used in data-driven analytics efforts support informed business intelligence decisions. However, these results currently only isolated dispersed parts production process. At same time, full integration artificial (AI) all is lacking. In this context, goal manuscript present a...
The European Union has set targets to reduce the greenhouse gases emissions in total energy consumption as a part of securing clean initiative and efforts carbon reductions 90%, compared 1990 ones, until 2050. transport sector is particularly exacerbating above problems. Focusing on their fight, authorities have invested continue invest electric propulsion. In Union, mobility grown tremendously last decade. Specifically, more automobile industries are turning interest technology replace...
The diversity of applications that current and emerging Wireless Sensor Networks (WSNs) are called to support imposes different requirements on the underlying network with respect delay loss, while at same time WSN its own intricacies. satisfaction these highly depends metric upon which forwarding routes decided. In this view, IETF ROLL group has proposed RPL routing protocol, can flexibly work various metrics, as long they hold specific properties. system implementer/user is free decide...
5G is considered to be the technology that will accommodate development and management of innovative services with stringent diverse requirements from end users, calling for new business models industry. In this context, efficient Network Services (NS) serving specific vertical industries spanning across multiple administrative domains heterogeneous infrastructures challenging. The main challenges regard provision NSs considering Quality Service (QoS) per industry along optimal usage...
The standardization of passive optical networks capable transporting Ethernet frames at gigabit-per-second speeds, currently in progress both ITU-T and IEEE, constitutes a major milestone toward cost-effective photonization the last (aka first) mile. article presents an gigabit PON (GPON) system aligned with philosophy evolving FSAN (full service access network) specification, which focuses on efficient support any level quality service. intelligence this system, terms traffic guarantees,...
The energy sector represents undoubtedly one of the most significant "test cases" for 5G enabling technologies, due to need addressing a huge range very diverse requirements deal with across variety applications (stringent capacity smart metering/AMI versus latency supervisory control and fault localization).However, effectively support utilities along their transition towards more decentralized renewable-oriented systems, several open issues still remain as networks management automation,...
Blockchain technology can have numerous applications in the shipping industry (although it is a newcomer blockchain technology) as provides transparency, security, and cost reduction financial transactions. Although at its early steps, this has been applied industry. The majority of related literature deals with applicability various processes company supply chains. Instead, paper focuses on willingness companies to adopt through an exploratory survey. It develops framework based slightly...
The advancement and acceptance of new technologies often hinges on the level understanding trust among potential users. Blockchain technology, despite its broad applications across diverse sectors, is met with skepticism due to a general lack incidents illicit activities in cryptocurrency domain. This study aims demystify blockchain technology by providing an in-depth examination application novel blockchain-based card game, centered around renewable energy sustainable resource management....
Abstract The steadily rising demand for multimedia and data services, the falling cost omnipresence of Ethernet maturity passive optical networks (PON) technology, promise to radically change landscape in local loop. heart a gigabit PON system (recently standardized by FSAN/ITU) is medium access controller (MAC), which arbitrates upstream link among users with fluctuating traffic demands effects multiplexing concentration policy. At same time, it has safeguard service quality enforce...
The majority of research and development efforts in the area Wireless Sensor Networks (WSNs) focus on WSN systems that are dedicated for a specific application.
