Two New Quorum Based Algorithms for Distributed Mutual Exclusion
Two novel suboptimal algorithms for mutual exclusion in distributed systems are presented. One is based on the modi cation of Maekawa's grid based quorum scheme. The size of ...

Cheap or Flexible Sensor Coverage
We consider dual classes of geometric coverage problems, in which disks, corresponding to coverage regions of sensors, are used to cover a region or set of points in the plane. The...

On the Complexity of Approximating TSP with Neighborhoods and Related Problems
We prove that various geometric covering problems, related to the Travelling Salesman Problem cannot be efficiently approximated to within any constant factor unless P = NP. This ...

The Parameterized Complexity of the Rectangle Stabbing Problem and Its Variants
We study the parameterized complexity of an NP-complete geometric covering problem called d-dimensional Rectangle Stabbing where we are given a set of axis-parallel d-dimensional h...
