A lot of attention has been given to multihop wireless networks lately but further research in particular through experimentation is needed. This attention has motivated an increase in the number of deployments both indoor and outdoor. These testbeds which require a significant amount of resources during both deployment and maintenance are used to run measurements in order to analyze and understand the limitation and differences between analytical or simulation-based figures and the results from real-life experimentation. This paper makes two major contributions i first we describe a novel wireless multihop testbed which we name FloorNet that is deployed and operated under the false floor of a lab in our Computer Science building. This false floor provides a strong physical protection that prevents disconnections or misplacements as well as radio shielding to some extent thanks to the false .
