Abstract:
This thesis covers the development of the wireless sensor network that will be used by the GeoPebble Wireless Seismic Sensor Network. The NSF-funded GeoPebble project requires a wireless network capable of sending large amounts of seismic data from as many as 150 separate geophysical sensing nodes scattered across a physically large area. A wireless network must be specially designed to meet the requirements of this system. In this thesis, the system requirements are defined, hardware and network type are specified from the requirements, and a networking protocol is specified to enable communication between the nodes and a central computer. Of particular interest is the use of time-division multiple-access techniques to achieve high data throughput during periods of fast seismic sampling. Finally, the specified network is simulated, and the results of the simulation are presented and evaluated on how well they meet the specified requirements.
