Abstract

A wireless data transmission system was developed and implemented for use in real-time 3D geophysical sensing. Server and Client applications were designed to run on a stationary computer and a mobile computer attached to the geophysical sensor, respectively. Several methods for optimizing communication over wireless networks using commonly available hardware were tested and compared, and a scheme for varying the size of transmissions in accordance with the recent performance of the wireless network was chosen. The final system was integrated with a 3D Ground Penetrating Radar (GPR) system and tested in a field experiment that spanned two weeks and involved the acquisition of 16 data volumes. The system performed successfully throughout the experiment and provided necessary feedback to assist in the error-free acquisition of all data volumes. Future development of the system is discussed in order for the system to support an automated wireless geophysical sensor network with multiple client sensors moved around the survey area by automated robots.
