Mobility modeling and traffic analysis in three-dimensional indoor environments

Abstract

To efficiently plan future personal communications services (PCS's), we need to solve various mobility/traffic problems in one-dimensional (1-D), two-dimensional (2-D), and three-dimensional (3-D) micro or picocell environments. However, mobility/traffic problems have thus far primarily been studied in 1-D and 2-D cell structures, In this paper, we extend the previous mobility modeling from 1-D or 2-D space to 3-D indoor building environments by considering the proper boundary conditions on each floor and analytically modeling mobility in multistory buildings to estimate the number of handoffs, We then propose a blocking probability model with mobility as a traffic model in 3-D indoor environments. Utilizing this model, we can obtain the required number of channels per cell under the given blocking probability constraint, These results can be utilized in planning the networks of future PCS's.
