Detecting Node Compromise in Hybrid Wireless Sensor Networks Using Attestation Techniques
Abstract. Node compromise is a serious threat in wireless sensor networks. Particular in networks which are organized in clusters, nodes acting as cluster heads for many cluster no...

Impulse noise removal by spectral clustering and regularization on graphs
In this paper we present a method for impulse noise removal that makes use of spectral clustering and graph regularization. The image is modeled as a graph and local spectral anal...

On the sample mean of graphs
— We present an analytic and geometric view of the sample mean of graphs. The theoretical framework yields efficient subgradient methods for approximating a structural mean and ...

Visualizing Large Graphs with Compound-Fisheye Views and Treemaps
Compound-fisheye views are introduced as a method for the display and interaction with large graphs. The method relies on a hierarchical clustering of the graph, and a generalizat...

A Distributed Performance Analysis Architecture for Clusters
The use of a cluster for distributed performance analysis of parallel trace data is discussed. We propose an analysis architecture that uses multiple cluster nodes as a server to ...
