EvalVSN: A new tool for video quality evaluation in Wireless Sensor Networks

Wireless video sensor networks (WVSN) are foreseen to be a key driver of the development of pervasive applications of every-day life. They trigger very challenging problems due to their constrained nature in terms of energy, bandwidth, processing and storage means. In order to be able to assess the performances of their proposals, WVSN´s researchers community needs a transmission and evaluation tool that considers WSN specific characteristics. In this paper, we propose EvalVSN, a new tool for video transmission and evaluation targeted to WVSN. EvalVSN allows both real and simulation-based video transmission and evaluation in WSN. Currently application modules that make use of EvalVSN trace files are available in TinyOS, ns2 and Castalia environments.
