Towards User-Centric Intelligent Network Selection in 5G Heterogeneous Wireless Networks - A Reinforcement Learning Perspective... Towards User-Centric Intelligent Network Selection in 5G Heterogeneous Wireless Networks - A Reinforcement Learning Perspective (Hardcover, 1st ed. 2020)
Zhiyong Du, Bin Jiang, Qihui Wu, Yuhua Xu, Kun Xu
R2,789 Discovery Miles 27 890 Ships in 10 - 15 working days

This book presents reinforcement learning (RL) based solutions for user-centric online network selection optimization. The main content can be divided into three parts. The first part (chapter 2 and 3) focuses on how to learning the best network when QoE is revealed beyond QoS under the framework of multi-armed bandit (MAB). The second part (chapter 4 and 5) focuses on how to meet dynamic user demand in complex and uncertain heterogeneous wireless networks under the framework of markov decision process (MDP). The third part (chapter 6 and 7) focuses on how to meet heterogeneous user demand for multiple users inlarge-scale networks under the framework of game theory. Efficient RL algorithms with practical constraints and considerations are proposed to optimize QoE for realizing intelligent online network selection for future mobile networks. This book is intended as a reference resource for researchers and designers in resource management of 5G networks and beyond.

Direct Modeling For Computational Fluid Dynamics: Construction And Application Of Unified Gas-kinetic Schemes (Hardcover): Kun... Direct Modeling For Computational Fluid Dynamics: Construction And Application Of Unified Gas-kinetic Schemes (Hardcover)
Kun Xu
R3,108 Discovery Miles 31 080 Ships in 10 - 15 working days

Computational fluid dynamics (CFD) studies the flow motion in a discretized space. Its basic scale resolved is the mesh size and time step. The CFD algorithm can be constructed through a direct modeling of flow motion in such a space. This book presents the principle of direct modeling for the CFD algorithm development, and the construction unified gas-kinetic scheme (UGKS). The UGKS accurately captures the gas evolution from rarefied to continuum flows. Numerically it provides a continuous spectrum of governing equation in the whole flow regimes.

A Unified Computational Fluid Dynamics Framework from Rarefied to Continuum Regimes (Paperback): Kun Xu A Unified Computational Fluid Dynamics Framework from Rarefied to Continuum Regimes (Paperback)

R537 Discovery Miles 5 370 Ships in 12 - 17 working days

This Element presents a unified computational fluid dynamics framework from rarefied to continuum regimes. The framework is based on the direct modelling of flow physics in a discretized space. The mesh size and time step are used as modelling scales in the construction of discretized governing equations. With the variation-of-cell Knudsen number, continuous modelling equations in different regimes have been obtained, and the Boltzmann and Navier-Stokes equations become two limiting equations in the kinetic and hydrodynamic scales. The unified algorithms include the discrete velocity method (DVM)-based unified gas-kinetic scheme (UGKS), the particlebased unified gas-kinetic particle method (UGKP), and the wave and particle-based unified gas-kinetic wave-particle method (UGKWP). The UGKWP is a multi-scale method with the particle for non-equilibrium transport and wave for equilibrium evolution. The particle dynamics in the rarefied regime and the hydrodynamic flow solver in the continuum regime have been unified according to the cell's Knudsen number.
