Abstract:
The rapid technological evolution in sensors, sensor platforms and networking is enabling the deployment
of large sensor networks for "live" monitoring of seismic activity with high spatial resolution. In this regard,
this paper describes our work in developing an online "High Throughput Seismic Sensor Network". We
present the architecture and implementation comprising seismic sensors and servers (running data collection
services) connected through internet-enabled technologies. We validate and assess the system, as well as
identify bottlenecks, by means of experimentation. Based on the collected empirical data, we were able to
identify methods and tools to support effective planning and implementation of sensor networks based on
two main indicators: Sensor Network Transmission Rate (SNTR), which provides the overall network
sensor data transmission throughput and thus an indication of the required network capacity; and CPU
Sensor Network Performance Index (CSNPI), which pro
vides an indication of a server capability to handle
network sensor data. As we progress in our work to field deploy seismic sensor networks, we will continue
to use these tools to plan and deploy future sensor networks, as well as assess improvements and
modifications along the way.
