DTAC-ADMM: Delay-Tolerant Augmented Consensus ADMM-based Algorithm for Distributed Resource Allocation

no code implementations30 Aug 2022 Mohammadreza Doostmohammadian, Wei Jiang, Themistoklis Charalambous

Every node locally updates its state toward optimizing a global allocation cost function via received information of its neighbouring nodes even when the data exchange over the network is heterogeneously delayed at different links.

Linear TDOA-based Measurements for Distributed Estimation and Localized Tracking

no code implementations26 Apr 2022 Mohammadreza Doostmohammadian, Themistoklis Charalambous

We present the minimal conditions on the remaining sensor network (after link/node removal) such that the distributed observability is still preserved and, thus, the sensor network can track the (single) maneuvering target.

no code implementations4 Apr 2022 Mohammadreza Doostmohammadian, Themistoklis Charalambous

Instead, only instantaneous deviation of the residuals raises the alarm in the stateless case without considering the history of the sensor outputs and estimation data.
