摘要
We introduce the framework of cooperative simultaneous localization and tracking (CoSLAT), which provides a consistent combination of cooperative self-localization (CSL) and distributed target tracking (OTT) in sensor networks without a fusion center. CoSLAT extends simultaneous localization and tracking (SLAT) in that it uses also intersensor measurements. Starting from a factor graph formulation of the CoSLAT problem, we develop a particle-based, distributed message passing algorithm for CoSLAT that combines nonparametric belief propagation with the likelihood consensus scheme. T he proposed CoSLAT algorithm improves on state-of-the-art CSL and OTT algorithms by exchanging probabilistic information between CSL and OTT. Simulation results demonstrate substantial improvements in both self-localization and tracking performance.
