Differential Evolution for VNE-5G Scenarios
2021 11th IFIP International Conference on New Technologies, Mobility and Security (NTMS), 2021Network slicing is a key component of the envisioned 5G network. The slicing process is mathematically known as a virtual network embedding problem (VNE). Embedding a large number of virtual networks to a real physical network over time is an NP-Hard problem, and it becomes more complex when regarding different requirements of distinct types of network

Requirements Engineering, 2004
Scenarios have been shown to be very helpful in identifying and communicating requirements for computer-based systems (CBSs). However, they appear not to be applicable to the rest of the CBS development process. Making scenarios more useful for the entire software development lifecycle requires integrating scenarios to other representations used during

Evolution scenarios towards UMTS
Proceedings of ICUPC - 5th International Conference on Universal Personal Communications, 2002The Universal Mobile Telecommunications System (UMTS) representing the major third generation mobile communications system is currently under development. One important aspect for the implementation of UMTS is the evolution from existing fixed and mobile telecommunications systems towards the support of UMTS capabilities.

Evolution in recycling scenario
AIP Conference Proceedings, 2010The recycling model argues the existence of an evolutionary connection between low mass X‐ray binaries and radio millisecond pulsars. The main difficulties which this model finds in predict the parameters of the fully recycled millisecond pulsars, as mass and spin period, can be overcome by the onset of the so‐called radio‐ejection mechanism. This work

Evolution scenario towards WDM-PON
Journal of Optical Communications and Networking, 2009In this paper we present and critically discuss different wavelength division multiplexing passive optical network (WDM-PON) architectures compatible with pre-existing gigabit PON (GPON) infrastructures. The concurrent use of the trunk fiber permits a hitless evolution from an existing time division multiplexing optical access network to a pointto ...

A framework for scenario evolution
Proceedings of IEEE International Symposium on Requirements Engineering: RE '98, 2002We report on a framework for scenario evolution. We have studied, based on a laboratory case study, the evolution of scenarios from elicitation to coding, thus using the requirements baseline in a full cycle. Considering our observations of over a hundred and fifty scenarios we discovered a series of relationships and operations that occurred during ...

Prioritising scenario evolution
Proceedings Fourth International Conference on Requirements Engineering. ICRE 2000. (Cat. No.98TB100219), 2002Use cases are currently used in requirement elicitation and analysis. They describe in natural language the complete functionality of a proposed system. In most projects, the amount of detail put into eliciting and documenting a use case is usually dependent on the time and resources available.

Scenario evolution in requirements elicitation processes
Proceedings of the 4th international workshop on Principles of software evolution - IWPSE '01, 2002Scenario-based approach is one of the promising techniques not only to elicit requirements from stakeholders, but also to achieve user-participatory development. The techniques to construct scenarios of high quality with less efforts are necessary. In addition, since during developing a system its requirements are frequently changed by customers and/or

The ecological scenario of Lepidopteran evolution
Entomological Review, 2007Soil detritophagy has been hypothesized to be the ancestral feeding type of the Lepidoptera as evidenced by the larval feeding habits of Zeugloptera. The ancestral feeding type, as well as mycetophagy and other closely related types of feeding, is still retained in Hepialomorpha, many Tineiformes, and some Cossiformes.

Cryptoviral Extortion: Evolution, Scenarios, and Analysis
2016“Cryptography” is a blessing to cyber security. People can store information securely and communicate privately over long distances. It is rapidly advancing and improving, but it is also making a ladder for cryptography-based viral attacks. This paper gives better understanding of the concept of “Cryptovirology” which presents how cryptography can also
