Abstract

Geostatistical methods are very useful tools for spatial forecasts in many research domains. The usage of these methods in the computer science domain is still in its infancy. There were attempts to use simulation and estimation geostatistical methods used in previous research to spatial Web systems performance forecasts. As the results are quite encouraging, therefore, authors decided to carry out further investigations in this field. This chapter presents an overview of the work concerning the use of geostatistical methods and the analysis of the impact of various factors on the accuracy of spatial Web performance forecasts for servers belonging to different Autonomous Systems (ASs). Forecasts were made by using geostatistical methods. The data for research was collected in active Internet Web Performance measurements carried out by software agents monitoring a group of Web servers. In this research, the network routes from agents in Gdansk and Wroclaw to European Web servers are considered.
