Abstract [en]

The aim of this project is to analyze a data log of wireless packet traffic, and to produce: (1) models for dynamic fluctuations in wireless channel and link quality, and, (2) a design for real-time communications over the given wireless channel. The models and designs are useful in setting up real-time communications in a vehicular test track (www.astazero.com). The data log came from experimental measurements at the test track. From this data, we fitted simple models for packet losses and retransmissions in the wireless communication system. These models took the form of a combination of a statistical model for the packet losses, with a deterministic model for retransmissions of lost packets. Such fitted models can be used to predict the average quality of vehicle position monitoring based on periodically transmitted position information. Such predictions help us decide the feasibility of safe and reliable conduct of testing with two or more moving test objects.
