Distributed Clustering Strategies in Industrial Wireless Sensor Networks
Abstract: Wireless sensor networks (WSNs) can provide numerous benefits in industrial automation. By removing the cable infrastructure, the wireless architecture enables the possibility for nodes in a network to dynamically and autonomously group into clusters according ding to the communication features and the data they collect. This capability allows to leverage the flexibility and robustness of industrial WSNs in supervisory intelligent systems for high high-level level tasks, such as, for example, environmental sensing, conditi condition on monitoring, and process automation. In this paper, a clustering strategy is studied that partitions a sensor network into a nonfixed number of nonoverlapping clusters according to the communication network topology and measurements distribution: To this aim, both a centralized and a distributed algorithm are designed that do not require a cluster-head cluster structure or other network assumptions. As a validation, these strategies are tested on a real dataset coming from a structured environment and the effectiveness veness of the clustering procedure is also investigated to perform anomalies detection in an industrial production process.
