TLDR
This paper considers large cellular mobile networks with dynamic channel allocation in which the arrival rates, holding times and handover probabilities for the different cells are identical.Abstract:
This paper considers large cellular mobile networks with dynamic channel allocation in which the arrival rates, holding times and handover probabilities for the different cells are identical. Such networks could model, for example, cellular networks in suburban areas. Different methods of analysing these networks are compared. These methods fall into two basic categories, those which approximate a network with a smaller finite network and those which consider the expected performance of a cell within an environment consisting of cells with identical properties. Simplifications of these methods which arise out of the reversibility of a symmetric cellular network are also discussed.read more

Genetic algorithms applied to cellular call admission: local policies
Aylin Yener,Christopher Rose +1 more
TL;DR: This paper defines local call admission policies that make admission decisions based on partial state information and finds the best double threshold policies by exhaustive search for both 1-D and Manhattan model cellular networks and shows that they almost always outperform the best trunk reservation policies for these systems.

Call admission control for an adaptive heterogeneous multimedia mobile network
Wei Li,Xiuli Chao +1 more
TL;DR: A novel call admission control (CAC) scheme for an adaptive heterogeneous multimedia mobile network with multiple classes of calls is investigated here and it is proved that the stationary distribution of the number of calls in the network has a product form.

Estimation of performance measures for product form cellular mobile communications networks
TL;DR: It is shown that the restrictive assumption of reversible routing is not required for the network population distribution to be of product form, and the notoriously difficult task of obtaining performance measures derived from product form expressions is attacked by an efficient method based on importance sampling.

The impact of mobility on cellular network configuration
Bezalel Gavish,Suresh Sridhar +1 more
TL;DR: The results of these experiments show that the proposed model, where handoff rates are state-dependent, captures additional traffic due to mobility when compared to the traditional method of modeling handoffs using information about the average behavior.

Reversibility and Stochastic Networks
TL;DR: This classic in stochastic network modelling broke new ground when it was published in 1979, and it remains a superb introduction to reversibility and its applications thanks to the author's clear and easy-to-read style.
