Adaptive resource allocation in metropolitan area cellular mobile radio systems

Abstract

It is shown that microcellular structures which will be found in future high-density traffic metropolitan areas require the application of adaptive methods for efficiently allocating the radio resource. Different dimensions of adaptation-adaptive base station allocation, dynamic channel allocation, and adaptive power control-are considered in an integrated manner. To answer if and how the proposed methods can work together, a generic algorithm comprising the different adaptive approaches is introduced. This was complemented by the derivation and definition of a comprehensive set of evaluation criteria. For the evaluation a simulation environment is developed, based on a Manhattan-like road grid structure, and comprising corresponding traffic and propagation models. First results indicate that the combined application of the different adaptation approaches yields the best performance.<>
