SPITFIRE: toward a semantic web of things
The developed world is awash with sensors. However, they are typically locked into unimodal closed systems. To unleash their full potential, access to sensors should be opened such that their dataExpand

Neighborhood-Based Topology Recognition in Sensor Networks
TLDR
We consider a crucial aspect of self-organization of a sensor network consisting of a large set of simple sensor nodes with no location hardware and only very limited communication range. Expand

A New Approach for Boundary Recognition in Geometric Sensor Networks
TLDR
We describe a new approach for dealing with the following central problem in the self-organization of a geometric sensor network: Given a polygonal region R, and a large, dense set of sensor nodes that are scattered uniformly at random in R. Expand

Exact solutions and bounds for general art gallery problems
TLDR
We present a primal-dual algorithm based on linear programming that provides lower bounds on the necessary number of guards in every step and—in case of convergence and integrality—ends with an optimal solution. Expand
