A Framework for Localization and Clustering in IoT Enabled Wireless Sensor and Actor Networks

Wireless sensor and actor networks (WSANs) compose of ordinary sensor networks and actor devices equipped with various capabilities. These networks are crucial technologies which are located at the communication layer of Internet of things. Actors (agents) are employed to provide decentralized control of the sensor networks. We propose an actor controlled framework for localization and clustering in sensor networks. To the best of our knowledge, our framework is the first which offers both localization and clustering within constant message complexity per node. In this structure, a mobile actor device traverses the sensor network to localize and cluster the sensor nodes. Total energy consumption of the sensor nodes using this method are reduced compared to the distributed approaches. Moreover, cluster quality of our algorithms is better than their counterparts. We show that our framework provides a suitable infrastructure for cluster-based applications in an energy efficient manner.
