I-LENSE Testbeds |
|---|
We have developed/deployed a few testbeds for wireless sensor network experiments. The major hardware platforms we are using now are the Mica Motes designed by UC Berkeley, the PC/104s that available as COTS products from a couple of companies, and Stayton based nodes from Intel.
We currently maintain and operate several testbeds.
Mote Nodes
Mica and Mica2 Motes are designed by UC Berkeley as a testbed for wireless sensor network experiments. They are running an event-driven operating system called TinyOS. Motes can be used as stand alone nodes. They can also be connected with PC/104s or Staytons to form a tiered architecture.
DATUNR Underwater testbed
The DATUNR project is developing an always-available and remotely-accessible underwater networking testbed in the Marina del Rey harbor. The testbed will support remote access to hosts with WHOI Micromodems and SNUSE acoustic modems.
In the past we have operated several additional testbeds. Some can be redeployed if there is research interest.
PC/104 Based NodesPC/104 based nodes are mainly funded by DARPA SenseIT program for SCADDS project. It is built upon off-the-shelf PC/104 based products. The operation system is Linux. Currently we have 30 nodes: 14 of them are semi-permanently deployed on 10th and 11th floors, others can be deployed ad hoc on hallways to create interesting experiment scenarios.
Stayton Based Nodes
Staytons are an early 2003 version of X-Scale embedded node developed by Intel. We have 12 Staytons deployed as part of our MACSS work.
Stargate Based Nodes
Stargates are the next-generation X-Scale board sensor node developed by Intel and manufactured by
Crossbow. We are expecting to
deploy 30 Stargates by December, 2003 to complement our PC/104 and Stayton nodes.
WinsNG sensor nodes were developed by Sensoria Corporation www.sensoria.com under the DARPA SenseIT program. Currently we have 10 WinsNG nodes.
Button boxes are made by Intel as a simple housing with user interface extension for MICA2Dot Motes. We have deployed 10 button boxes on the 11th floor for the "Follow Me" application. We plan to eventually deploy about 70 button boxes on the 11th floor.
