As part of a broader organisational restructure, data networking research at Swinburne University of Technology has moved from the Centre for Advanced Internet Architecture (CAIA) to the Internet For Things (I4T) Research Lab.

Although CAIA no longer exists, this website reflects CAIA's activities and outputs between March 2002 and February 2017, and is being maintained as a service to the broader data networking research community.

Web Object Change Interval Estimation Simulator (WOCIES)

WOCIES is a simulator for designing and investigating web robots that estimate the average change interval of objects on the Web. Object change events are modeled as a Poisson process. The simulator has many variable parameters including:

Using the simulator you can test various combinations of these parameters and compare the results to determine the most efficient robot configuration.
