Reconfiguration during data collection for many-to-one routing in wireless sensor networks

This work discusses the concurrent applications of data collection and reconfiguration, and proposes a novel reconfiguration scheme during data collection. The proposed scheme incorporates the advantages of both proactive and reactive protocols into one system: using proactive protocol to collect continuous data and reactive protocol to reconfigure each remote node of the network. In addition, three methods with suppression mechanism are proposed in which two using the topology information as hints and one using simple flooding. Finally, we propose a cost-saving and reliable reconfiguration scheme during data collection to efficiently combine the table-driven data collection tree and three reconfiguration methods. The results of simulation show the effectiveness of the scheme.
