A new analytical method in user mobility modelling in wireless network

摘要

In mobile communications, mobility modeling is involved in several aspects related to signaling and traffic load analysis. In particular, the accuracy of mobility models becomes essential for the evaluation of system design alternatives and network implementation cost issues. In this paper, we propose a new mobility model, which is appropriate for the analysis of the full range of mobile communications design issues. This model provides different levels of details of the user mobility behavior and can be adapted on any environment topology. This model is based on the direction of user movements that are modeled by discrete time, discrete state Gauss-Markov model and also, is based on the user velocity that is modeled as a variable mean and variance Gaussian process.
