Approximating maximum integral flows in wireless sensor networks via weighted-degree constrained k-flows

13 years 9 months ago

Download www.openu.ac.il

We consider the Maximum Integral Flow with Energy Constraints problem: given a directed graph G = (V, E) with edge-weights {w(e) : e E} and node battery capacities {b(v) : v V }...
