In this paper we discuss a robust aggregation framework that can detect spurious
measurements and refrain from incorporating them in the computed aggregate values. Our
framework can consider different definitions of an outlier node, based on a specified
minimum support. Our experimental evaluation demonstrates the benefits of our approach.
