An Adaptive Algorithm Based on PSO for Generating Inhomogeneous Triangular Cells

Abstract

This paper is concerned with the distance characteristics of terrestrial propagation as well as the optimal allocation of base stations (BSs) in complicated propagation environments. First, we review 1-ray and 2-rays models to simulate terrestrial electromagnetic wave propagations by introducing amplitude modification factor and propagation order of distance (β). Second, we propose an algorithm to determine the propagation parameters based on the Hata's empirical equations for introducing the communication distance function to estimate wireless accessibility. Finally, based on the particle swarm optimization (PSO), we propose an adaptive algorithm for generating inhomogeneous triangular cells to optimally allocate BSs.
