Jennic is offering on its website a ZigBee network stack object library and all associated support including user guides, programming and reference manuals, and application notes.

The ZigBee network stack available on the web site can be evaluated on Jennic’s JN5121-EK010 developer kit and the wireless application programmed onto chips and modules supplied by Jennic.

Priced at US$1,299, and available ex-stock from Jennic’s distributors, the kit contains all the software tools and hardware required to develop and monitor wireless sensor network products, including the ZigBee network stack.

A paper on “Deploying a Wireless Sensor Network on an Active Volcano”, by Geoff Werner-Allen, Konrad Lorincz, Mario Ruiz, Omar Marcillo, Jeff Johnson, Jonathan Lees, and Matt Welsh, has been published in the IEEE Internet Computing, Special Issue on Data-Driven Applications in Sensor Networks, March/April 2006.

Augmenting heavy and power-hungry data collection equipment with lighter, smaller wireless sensor network nodes leads to faster,larger deployments.Arrays comprising dozens of wireless sensor nodes are now possible,allowing scientific studies that aren’t feasible with traditional instrumentation.Designing sensor networks to support volcanic studies requires addressing the high data rates and high data fidelity these studies demand.The authors’ sensor-network application for volcanic data collection relies on triggered event detection and reliable data retrieval to meet bandwidth and data-quality demands.
