Two demos using SensLAB: Very large scale open WSN testbed

We present SensLAB, a very large scale wireless sensor network testbed
¹
. SensLAB is distributed among 4 sites having different topologies and consists of 1024 wireless nodes based on open source hardware & software. Within a given site, each one of the 256 nodes is able to communicate via its radio interface (868Mhz or 2.4Ghz) to its neighbors. Furthermore, every sensor node is potentially configurable as a sink node and can exchange data with any other sink node of the whole SensLAB testbed and/or Internet application. The testbed is designed to achieve reproducibility of experimentation, while also supporting evaluation of protocols and applications in real world settings. It allows to monitor transparently, i.e., without any insertion/modification within the code, any deployed application in terms of energy consumption or radio activity. The main benefits of SensLAB for the users are to reduce the costs in terms of: infrastructure investment, maintenance cost and operating cost. With SensLAB you can be up and running minutes after you are assigned an account! SensLAB's main and most important goal is to offer an accurate open access multi-users scientific tool to support the design, development, tuning, and experimentation of real large-scale sensor network applications. During this demo, we propose to demonstrate the interests of the SensLAB testbed by developing and running two experimental scenarii that highlight the services offered by SensLAB.
