Tradeoff Analysis and Optimization of Security and Spatial Resolution for Sensor Networks

In this study, we investigate the correlation between security and spatial resolution - a measure of service quality - in cluster-based wireless sensor networks (WSN). We analyze the tradeoff between these two concepts resulting from the limited channel capacity and propose a method to determine the best tradeoff between security and spatial resolution for cases where network capacity is not sufficient to support required levels. We also present some numerical results obtained by application of the proposed method to a sample sensor network.
