Abstract
Self-localizing wireless sensor networks (WSNs) with acoustic and optical sensors are well suited to detect the entrance of an object, such as a land or air vehicle, into a perimeter. A WSN is a combination of independent devices that typically uses sensors to monitor a given area and send data to a database or Internet cloud-based system. To cover a large area, for example a 500-meter radius perimeter, a nested ring configuration of detectors was used this summer for experiments. The outer-ring nodes (ORN) monitor and gather data of the area of interest, and the inner-ring nodes (IRN) collect data from a set of ORNs along with monitoring the interior local area. During the implementation, one IRN along with a subset of its ORNs was tested. Experiments to connect the ORNs to the IRN showed that monitoring and collection of data was reliable, and updates generated form the ORN to the IRN when objects were detected. Based on initial results, future work is envisioned to extend the effectiveness of the acoustic/optical WSN, including: 1) having the IRN send collected data to an outside source, 2) detecting acoustic signatures of the target object, and 3) enabling monitoring when the ORN cannot connect to the IRN. Applications for the acoustic/optical WSN could also be explored such as use with drone detection at airports or for anti-poaching monitoring systems for game parks.
