Localization and routing in sensor networks by local angle information
Location information is very useful in the design of sensor network infrastructures. In this paper, we study the anchor-free 2D localization problem by using local angle measureme...

The complexity of flow on fat terrains and its i/o-efficient computation
We study the complexity and the I/O-efficient computation of flow on triangulated terrains. We present an acyclic graph, the descent graph, that enables us to trace flow paths in ...

Guaranteed-Delivery Geographic Routing Under Uncertain Node Locations
—Geographic routing protocols like GOAFR or GPSR rely on exact location information at the nodes, because when the greedy routing phase gets stuck at a local minimum, they requir...

Practical and robust geographic routing in wireless networks
Existing geographic face routing algorithms use planarization techniques that rely on the unit-graph assumption, and thus can exhibit persistent routing failure when used with rea...

General approximation schemes for min-max (regret) versions of some (pseudo-)polynomial problems
While the complexity of min-max and min-max regret versions of most classical combinatorial optimization problems has been thoroughly investigated, there are very few studies abou...
