We propose a model to represent the health of WSNs that allows us to evaluate a network's ability to execute its functions. Central to this model is how we quantify the importance of each network node. As we focus on the availability of the network data, we investigate how well different centrality measures identify the significance of each node for the network connectivity. In this process, we propose a new metric named current-flow sink betweenness. Through a number of experiments, we demonstrate that while no metric is invariably better in identifying sensors' connectivity relevance, the proposed current-flow sink betweenness outperforms existing metrics in the vast majority of cases.
