Experimental analysis of simulated annealing based algorithms for the layout problem

TL;DR: The hybrid simulated annealing (HSA) algorithm as discussed by the authors uses the modified penalty algorithm to generate an initial solution and then improves it using simulated anealing, which is tested on single-row layout problems with facilities of unequal area.
Journal ArticleDOI

Semi-Distributed User Relaying Algorithm for Amplify-and-Forward Wireless Relay Networks

TL;DR: A semi-distributed user relaying algorithm, which can provide comparable system capacity, but has significantly reduced computational complexity, is proposed for amplify-and-forward wireless relay networks.
Reference BookDOI

Matrix-Analytic Methods in Stochastic Models

TL;DR: A tutorial overview with some extensions and new results matrix-analytic methods for Markov chains on a tree structure renewal theory and Queueing algorithms for matrix-exponential distributions determination of explicit solutions to a general class of Markov processes equilibrium distributions for level-dependent quasi-birth-and-death processes.
BookDOI

Queueing Theory for Telecommunications

TL;DR: This book presents clear concise theories behind how to model and analyze key single node queues in discrete time using special tools that were presented in the second chapter.
Journal ArticleDOI

Denial of Service Defence for Resource Availability in Wireless Sensor Networks

TL;DR: A review of denial of service attacks that affect resource availability in WSN and their countermeasure is presented by presenting a taxonomy and future research directions and open research issues are discussed.
