A probabilistic method for cooperative hierarchical aggregation of data in VANETs
We propose an algorithm for the hierarchical aggregation of observations in dissemination-based, distributed traffic information systems. Instead of transmitting observed paramete...

A quantitative assessment of structural errors in grid maps
Various common error sources affect the quality of a map, e.g., salt and pepper noise and other forms of noise that are more or less uniformly distributed over the map. But there ...

Optimality analysis of sensor-target localization geometries
The problem of target localization involves estimating the position of a target from multiple and typically noisy measurements of the target position. It is well known that the re...
