Virtual Network Embedding: A Survey
TLDR
A survey of current research in the Virtual Network Embedding (VNE) area is presented and a taxonomy of current approaches to the VNE problem is provided and opportunities for further research are discussed. Expand
Energy Efficient Virtual Network Embedding
TLDR
The well-known virtual network embedding problem (VNE) is extended to energy awareness and a mixed integer program (MIP) which provides optimal energy efficient embeddings is proposed which shows energy gains over the existing cost-based VNE approach. Expand
Queueing Networks and Markov Chains - Modeling and Performance Evaluation with Computer Science Applications, Second Edition
TLDR
The role of Probability and Statistics in simulation, and the role of tools in Simulation, in the development of Markov Chains and Queueing Networks, is explained in more detail. Expand
Energy-Efficient Cloud Computing
TLDR
The usage of methods and technologies currently used for energy-efficient operation of computer hardware and network infrastructure and some of the remaining key research challenges that arise when such energy-saving techniques are extended for use in cloud computing environments are identified. Expand
A survey of programmable networks
TLDR
A programmable networking model is presented that provides a common framework for understanding the state-of-the-art in programmable networks and a simple qualitative comparison of the surveyed work is presented. Expand
Dynamic key management in wireless sensor networks: A survey
TLDR
In this work, the state of the art dynamic key management schemes are classified into different groups and summarized based on the evaluation metrics, and several basic evaluation metrics are introduced. Expand
Performance tradeoffs of energy-aware virtual machine consolidation
TLDR
It is shown that the energy-optimal allocation of virtualized services in a heterogeneous server infrastructure is NP-hard and can be modeled as a variant of the multidimensional vector packing problem and a model to predict the performance degradation of a service when it is consolidated with other services is proposed. Expand
An approach to energy-efficient virtual network embeddings
TLDR
The modified algorithm is evaluated, showing that energy-efficiency can be increased with only a minor impact on embedding quality regarding other metrics. Expand
Evaluating and modeling power consumption of multi-core processors
TLDR
This paper presents a methodology for estimating the power consumption of multi-core processors that takes into account resource sharing and power saving mechanisms and shows that it provides an accuracy within a maximum error of 5%. Expand
