Abstract [en]

It is important for the life time of a wireless sensornetwork (WSN) to reduce the amount of data transferred throughthe network. As a typical approach, sensor data is filtered beforepropagating updates, to a node at the edge of a network, whereit can be fused. Information Fusion inside the network canreduce the amount of data propagated, by fusing data beforeand in propagation, without losing the information value in it. Weexplore infrastructures for distributed fusion, with fusion nodeslocated at strategic nodes inside the network, as an approachof structured distributed fusion for WSNs. We propose aninfrastructure for a white-board approach that uses a distributedreal-time database with virtual full replication. With such anapproach, both raw and fused data are logically available at allnodes and physically available where used, such that only useddata will be propagated and use resources. The actual resourceusage will be relative to the actual demand for data, rather thanto the amount of data published at the white-board. We presentan exploration of such an infrastructure, and points out futurekey research questions for such a white-board approach.
