SensLAB - Very Large Scale Open Wireless Sensor Network Testbed

Universitede Strasbourg { firstName.lastName@unistra.frAbstract. This paper presents a precise description of SensLAB: VeryLarge Scale Open Wireless Sensor Network Testbed that has been devel-oped and deployed in order to allow the evaluation through experimen-tations of scalable wireless sensor network protocols and applications.SensLAB's main and most important goal is to o er an accurate openaccess multi-users scienti c tool to support the design, development tun-ing, and experimentation of real large-scale sensor network applications.The SensLAB testbed is composed of 1024 nodes over 4 sites. Each loca-tion hosts 256 sensor nodes with speci c characteristics in order to o era wide spectrum of possibilities and heterogeneity. Within a given site,each one of the 256 nodes is able both to communicate via its radio in-terface to its neighbors and to be con gured as a sink node to exchangedata with any other sink node of the whole SensLAB testbed. The hard-ware and software architectures that allow to reserve, con gure, deployembedded software, boot wireless sensor nodes and gather experimentaldata and monitoring information are described in detail. We also presentdemonstration examples to illustrate the use of the SensLAB testbed.
