Experimental analysis and characterization of a wireless sensor network environment

Existing testbeds, even though rare and specialized, are not often exploited to their full potential. Data collected during experimentation are usually used to evaluate some specific tested aspect. To further benefit from the knowledge gathered on a testbed and to obtain the insight into the WSN environment itself, we propose a thorough statistical analysis. Some of our analysis include radio link characterization, its correlation with environmental parameters as well as an insight into network dynamics from the point of view of a node and a link. We also discuss how testbeds should be designed or improved to provide more detailed information necessary for an advanced analysis.
