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...
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 ...

—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...
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...

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...
