Multi-Channel Sensor Boards for Real-Time Processing in
Large Wireless Sensor Networks

Our multi-channel FPGA-based sensor board offers numerous unique features and functionalities including:

High-performance, small-size and easy to interface with COTS Zigbee-based devices e.g., Telos-B or MICAz motes. Five high precision and fast analog channels designed for real-time sensor-level signal processing in large wireless sensor network environments. Onboard FPGA and memories for efficient implementation of flexible system structure and advanced sensor-level signal processing algorithms. Onboard radio for added capability for sensor- level self-localization. Multiple auxiliary channels for digital compass, GPS, and laser scanning. Supports multiple sensing modalities including acoustic, seismic, laser scanning, IR, etc. Suitable for either fixed site or small portable units.

With ISTI's developed technologies, the communication bandwidth and sensor-level processing limitations are overcome especially in moderately large wireless sensor networks. Current applications of our systems include (see Projects): acoustic localization and tracking of moving ground and airborne vehicles; transient event (e.g., gunshot) detection, localization and classification; sensor-level data compression for streaming large amount of data; and distributed network of scanning lasers for perimeter security and surveillance applications. Our hardware, software, and networking solutions and products can be modified, reconfigured and applied to a wide variety of distributed sensor networking applications.
