Distributed Error-Identification and Correction using Block-Sparse Optimization
Shiraz Khan, Inseok Hwang
The conventional solutions for fault-detection, identification, and reconstruction (FDIR) require centralized decision-making mechanisms which are typically combinatorial in their…
Exploiting Sparsity for Localization of Large-Scale Wireless Sensor Networks
Shiraz Khan, Inseok Hwang, James Goppert
Wireless Sensor Network (WSN) localization refers to the problem of determining the position of each of the agents in a WSN using noisy measurement information. In many cases, such…
Distributed Gaussian Mixture PHD Filtering under Communication Constraints
Shiraz Khan, Yi-Chieh Sun, Inseok Hwang
The Gaussian Mixture Probability Hypothesis Density (GM-PHD) filter is an almost exact closed-form approximation to the Bayes-optimal multi-target tracking algorithm. Due to its op…
Recovery of Localization Errors in Sensor Networks using Inter-Agent Measurements
Shiraz Khan, Inseok Hwang
A practical challenge which arises in the operation of sensor networks is the presence of sensor faults, biases, or adversarial attacks, which can lead to significant errors incurr…
