The document describes an approach for state estimation with delay constraints in wireless sensor networks. The approach jointly designs in-network estimation operations and an aggregation scheduling algorithm. Estimates from different sensors are optimally fused at relay nodes, which also predict estimates that cannot reach the sink before deadlines. An interference-free scheduling algorithm aggregates as much estimate information as possible to the sink within delay limits. Simulation results confirm the theoretical unbiasedness and optimality of the in-network estimation approach under different network settings.Read less
