Given a network of N nodes with the i-th sensor's observation xi isin RM, the matrix containing all Euclidean distances among measurements ||xi - xj || foralli, j isin {1,..., N} is a useful description of the data. While reconstructing a distance matrix has wide range of applications, we are particularly interested in the manifold reconstruction and its dimensionality reduction for data fusion and...
In this paper the self-localization problem for sensor networks is addressed. Given a set of nodes deployed in an environment, self-localization consists of finding out the location of all nodes in regard to any topology or metric of interest. Nodes are assumed to be equipped with a sensor board able to provide these inter-node distances. In addition, a few nodes are assumed to be equipped with some...
Controlled greedy sleep (CGS) is a recent k-coverage algorithm based on one-hop neighboring knowledge. This paper presents the controlled greedy Sleep algorithm and highlights its best use cases thanks to performance analysis. Studies have been performed within a ring topology. This specific topology enables CGS validation and the design of an energetic model. They are used to compare CGS performance...
