This paper concerns geometric disk problems motivated by base station placement problems arising in wireless network design. We first study problems that involve maximizing the coverage under various interference-avoidance constraints. A representative problem for this type is the maximum weight independent set problem on unit disk graphs, for which we present an exact solution whose complexity is exponential but with a sublinear exponent. Specifically, our algorithm has time complexity 2O(驴mlogm), where m is the number of disks. We then study the problem of covering all the clients by a collection of disks of variable radii while minimizing the sum of radii, and present a PTAS for this problem. |
