“…These studies have demonstrated the versatility of BT-based collected data for recognizing social patterns, inferring social relationships, creating networking structures [1]- [6] or even influencing mental health [7]. In addition, BT data has been leveraged for context-oriented opportunistic networking applications and epidemic modeling [28], [29], [31]. The outcomes of the social networks inference have been applied to many domains for providing improved networking services [2], designing communication overhead algorithms [4], or modeling social distance measures [28].…”

Bluetooth (BT) data has been extensively used for recognizing social patterns and inferring social networks, as BT is widely present in everyday technological devices. However, even though collecting BT data is subject to random noise and may result in substantial measurement errors, there is an absence of rigorous procedures for validating the quality of the inferred BT social networks. This paper presents a methodology for inferring and validating BT-based social networks based on parameter optimization algorithm and social network analysis (SNA). The algorithm performs edge inference in a bruteforce search over a given BT data set, for deriving optimal BT social networks by validating them with predefined ground truth (GT) networks. The algorithm seeks to optimize a set of parameters, predefined considering some reliability challenges associated to the BT technology itself. The outcomes show that optimizing the parameters can reduce the number of BT data false positives or generate BT networks with the minimum amount of BT data observations. The subsequent SNA shows that the inferred BT social networks are unable to reproduce some network characteristics present in the corresponding GT networks. Finally, the generalizability of the proposed methodology is demonstrated by applying the algorithm on external BT data sets, while obtaining comparable results.
