The quality of information (QoI) that sensor networks provide to the applications they support is an important design objective for their deployment and use. In this paper, we introduce a layered framework for QoI-centered evaluation of sensor network deployment. Considering the detection of transient events class of applications, the layered framework allows separation of the deployment evaluation in three steps: input pre-processing, core analysis, and result post-processing. The layering allows the creation of a rich, modular toolkit system for QoI-centered analysis that can accommodate both existing and new system modeling and analysis techniques. We demonstrate the utility of the framework by comparing the QoI performance of finite-sized sensor networks with general deployment topology, while, at the same time, deriving some new analysis results for the class of applications considered herein.
