Hierarchical analysis of GSM network performance data

چکیده
In this study, a method for hierarchical examination and visualization of GSM data using the Self-Organizing Map (SOM) is described. The data is examined in few phases. At first temporally averaged data is used and then, in each phase some of the data is discarded and the rest is examined in more detail. The SOM is used both in clustering and in visualization. The actual clustering is performed to the nodes of the SOM to lower the computational cost and to help to understand better the properties of the clusters.

Intelligent identification of vehicle’s dynamics based on local model network
This paper proposes an intelligent approach for dynamic identification of the vehicles. The proposed approach is based on the data-driven identification and uses a high-performance local model network (LMN) for estimation of the vehicle’s longitudinal velocity, lateral acceleration and yaw rate. The proposed LMN requires no pre-defined standard vehicle model and uses measurement data to identif...

In this paper we present an interference analysis which reveals capacity reserves for a hierarchical GSM radio network. In the investigated concept a low-power Cordless Telephony System reuses the frequencies of a cellular GSM system based on Total Frequency Hopping (T-FH) multiple access. Based on a novel simulation method, which considers the dynamics of a T-FH cellular network, we present re...

متن کاملA SOM Based Approach for Visualization of GSM Network Performance Data
In this paper, a neural network based approach to visualize performance data of a GSM network is presented. The proposed approach consists of several steps. First, a suitable proportion of measurement data is selected. Then, the selected set of multi-dimensional data is projected into two-dimensional space for visualization purposes with a neural network algorithm called Self-Organizing Map (SO...
متن کاملInterference Analysis for a Hierarchical GSM Network with Picocells using Total Frequency Hopping with Adaptive Frequency Allocation
In today’s cellular networks it becomes harder to provide the resources exactly in the place and at the time where and when they are needed. Frequency planning for a hierarchical cellular network, especially to cover hot-spots and indoor areas is a complicated and expensive task. We propose the use of Total Frequency Hopping in combination with Adaptive Frequency Allocation for picocells in a h...
