Description: This book is intended to provide an efficient introduction to the fundamental
concepts and principles underlying the study of queueing systems as they apply
to telecommunications networks and systems. Our objective is to provide
sufficient background to allow our readers to formulate and solve interesting
queueing problems in the telecommunications area. The book contains a selection
of material that provides the reader with a sufficient background to read
much of the queueing theory-based literature on telecommunications and networking,
understand their modeling assumptions and solution procedures, and
assess the quality of their results

Description: — Performance comparison of multiuser OFDM-TDMA and
OFDMA systems by considering physical and link cross-layer behavior
is conducted in this work. We provide a new framework for performance
evaluation that centers on “ scheduling” with several different
subcarrier/bit allocation schemes. The performance metrics include: the
bit rate, the bit error rate (BER), packet throughput and delay. The
instantaneous channel conditions of users are assumed to be available
at the base station, which can be achieved by channel estimation at the
mobile terminal (MT), and then fed back to the base station through
a control channel. To perform the link layer comparison, we model the
Rayleigh fading channel with a nite-state Markov chain, and adopt the
M/G/1 queueing model as the analytical tool. Computer simulation is
performed to verify conducted analytical results-— Performance comparison of multiuser OFDM-TDMA and

Description: The cross-entropy (CE) method attributed to Reuven Rubinstein is a general Monte Carlo approach to combinatorial and continuous multi-extremal optimization and importance sampling. The method originated from the field of rare event simulation, where very small probabilities need to be accurately estimated, for example in network reliability analysis, queueing models, or performance analysis of telecommunication systems. The CE method can be applied to static and noisy combinatorial optimization problems such as the traveling salesman problem, the quadratic assignment problem, DNA sequence alignment, the max-cut problem and the buffer allocation problem, as well as continuous global optimization problems with many local extrema.

Description: The model is built upon the assumption that the probabil-
ity distribution of available destinations among the bu ered frames at
the Base Station (BS) is approximately the same as the probability
distribution of the trac arriving to the BS, this is, the amount of
trac directed to each MN with respect to the total trac load. This
assumption leads to a simple, but accurate, queueing model for Multi-
user MIMO systems that accounts for the impact of a nite number of
active MNs in non-saturated conditions. The model is easily applicable
to any Multi-user MIMO scenario given that the probability density
function of the post-processing SINR (Signal to Interference and Noise
Ratio) for each MN is known. Platform: |

Description: 这是一个M/M/C/∞排队系统，其中顾客按照泊松流输入，服务时间按照负指数分布，有C个服务台的单列多台并列服务系统。在这种系统，顾客到达系统后排成一个队列，然后到空闲的服务台接受服务，而每个服务台的服务时间都服从相同参数的负指数分布，服务完毕后顾客自动离去。(This is a M/M/C/ infinity queueing system, where the customers enter the Poisson flow, the service time is distributed according to the negative exponent, and there are C single row multiple parallel service systems of the service stations. In such a system, customers arrive at the system in the rear row into a queue, then receive service at the idle service desk, while the service time of each service station obeys the negative exponential distribution of the same parameter. After the service is finished, the customer automatically goes away.) Platform: |
