The paper presents a model of a group of cells, exploiting the effects of connection handoff between cells, aimed at increasing the traffic capacity of a system. The analytical model proposed is based on the model of limited-availability group, which makes it possible to determine basic traffic characteristics in the system under consideration. The results of analytical calculations of blocking in a group of UMTS cells were compared with simulation data.

This paper proposes an analytical calculation method for determining occupancy distribution and blocking probability in multi-threshold state-dependent systems that simultaneously service multi-rate PCT1 and PCT2 traffic streams. The proposed analytical model is applied to calculate traffic characteristics in UMTS networks with streaming, adaptive and elastic services. The results of analytical calculations of blocking probability in the UMTS cell are compared with simulation data in order to evaluate accuracy of the proposed analytical model.

作者： M. Glabowski M. Sobieraj M. Stasiak Chair of Communication and Computer Networks Poznan University of Technology Poznan Poland

The paper proposes a new analytical approach to blocking probability calculation in wireless mobile networks with bandwidth reservation and connection handoff mechanisms, carrying a mixture of different traffic streams. This mixture can be composed of an arbitrary number of traffic classes, generated by a finite as well as an infinite population of traffic sources. The appropriate bandwidth reservation algorithm for a group of cells, exploiting the effects of connection handoff between cells, is also proposed. The results of analytical calculations of blocking probability in a group of UMTS cells with bandwidth reservation are compared with simulation data.

The article proposes an analytical method for determining traffic characteristics of systems which are offered overflow traffic composed of multi-rate traffic streams. Additionally, a method for determining parameters of the traffic overflowing from primary groups and an approximate method for dimensioning systems servicing multi-service switching networks with overflow traffic are also presented.

IEEE GLOBECOM 2007 - IEEE Global Telecommunications Conference

作者： Wojciech Kabacinski Marek Michalski Achille Pattavina Chair of Communication and Computer Networks Poznan University of Technology Poznan Poland Department of Electronics and Information Politecnico di Milano Italy

In this paper the new control algorithm for log 2 (N, 1, p) switching fabrics is proposed. This algorithm is the extension of the algorithm we propose for log 2 (N, 1, p) switching fabrics. The idea of the algorithm is to choose such a plane for the new connection in which this new connection will block the fewest number of possible future connections. Wide-sense nonblocking conditions are derived and proved when this algorithm is used for connection set up in such kind of switching fabrics with odd or even number of stages. The number of planes needed is the same as for the rearrangeable switching fabrics when the number of stages is even, and greater than for the rearrangeable switching fabric but lower than for the strict-sense nonblocking fabric, when the number of stages is odd.

作者： Mariusz Glabowski Slawomir Hanczewski Maciej Stasiak Chair of Communication and Computer Networks Poznań University of Technology Poznan Poland

The article discusses an analytical method of determining average bandwidth offered to a user in UMTS applying HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) technologies. The application of HSDPA/HSUPA increases the transmission speed between the base station and the end-user's terminal in UMTS networks. This has, in turn, made it possible for cellular systems operators to offer new services that require greater data flow both in the uplink direction and downlink direction such as, e.g., broadband Internet access.

作者： Mariusz Glabowski Adam Kaliszan Chair of Communication and Computer Networks Poznań University of Technology Poznan Poland

This paper presents an approach to simulation investigations of a full-availability group with multi-rate Poisson, Bernoulli and Pascal traffic streams. In the paper the models of a full-availability group with and without bandwidth reservation are described. The particular distributions of various traffic streams are also presented. The proposed simulator is based on events-scheduling approach. The paper deals also with implementation issues related to simulation research of the systems with Bernoulli, Poisson and Pascal traffic streams.

Solution techniques for Markov decision problems rely on exact knowledge of the transition rates, which may be difficult or impossible to obtain. In this paper, we consider Markov decision problems with uncertain transition rates represented as compact sets. We first consider the problem of sensitivity analysis where the aim is to quantify the range of uncertainty of the average per-unit-time reward given the range of uncertainty of the transition rates. We then develop solution techniques for the problem of obtaining the max-min optimal policy, which maximizes the worst-case average per-unit-time reward. In each of these problems, we distinguish between systems that can have their transition rates chosen independently and those where the transition rates depend on each other. Our solution techniques are applicable to Markov decision processes with fixed but unknown transition rates and to those with time-varying transition rates.
