Method synopsis

Deployment and operation of networked embedded sensor nodes for distributed acoustic monitoring using custom hardware and WaveScript programming language. Enables real-time processing and localization of acoustic events across wireless sensor networks.

Synthesized from method descriptions across 2 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — VoxNet: an interactive, rapidly-deployable acoustic monitoring platform (2008), ISPN 2008: Information Processing in Sensor Networks. The protocol was originally introduced by Automated wildlife monitoring using self-configuring sensor networks deployed in natural habitats (2007), Proceedings of the Twelfth International Symposium on Artificial Life and Robotics. Implementations in other papers (listed below) may differ.

1. Deploy VoxNet hardware nodes
   Eight VoxNet nodes were positioned in field locations maintaining consistent geographical topology spanning 140m by 70m area (2.4 acres). Nodes were packaged in weatherproof 1150 Pelican cases with integrated microphone arrays and external connectors. All nodes were battery powered with 8-hour operational lifetime from internal 5400mAh Li-ion batteries.
   Quantities: 8 nodes deployed across 2.4 acre area (140m x 70m), 8-hour battery life per nodeDuration: Multiple days of deployment during August 2007Conditions: Field deployment at Rocky Mountain Biological Laboratory, outdoor weather conditions including rain storms
   Equipment: VoxNet nodes, 1150 Pelican cases, 5400mAh Li-ion batteries, microphone arrays
2. Establish network connectivity
   Nodes formed ad-hoc mesh network using 802.11b wireless cards with 3.5 dBi antennas providing approximately 200m line-of-sight communication range. Gateway node positioned 200m from nearest sensor nodes connected to control server via wired Ethernet. IP routing implemented with user-space Dynamic Source Routing protocol.
   Quantities: 200m maximum communication range, 802.11b wireless, 3.5 dBi antennasDuration: Continuous network operation during deployment periodConditions: Outdoor wireless communication with potential signal quality variations
