Geostatistical Techniques for Practical Wireless Network Coverage Mapping
Computer Science PhD Candidate

The problem of mapping the extent of "usable" coverage of an existing wireless network is important in a large number of applications, including communicating the abilities of the network to users, identifying coverage gaps and planning expansion, and determining possible sources of interference with other networks. This thesis addresses fundamental but unsolved problems of measurement-based wireless coverage mapping: where should measurements be made, how many are necessary, and what can be said about the coverage at points that have not been measured. To address these problems, this thesis advocates a geostatistical approach using optimized spatial sampling and ordinary Kriging. This thesis shows that geostatistical approaches to sampling and interpolation are able to produce more accurate and robust coverage maps than the current state of the art methods.
