Abstract

We consider the aggregation problem in radio networks: find a spanning tree in a given graph and a conflict-free schedule of the edges so as to minimize the latency of the computation. While a large body of literature exists on this and related problems, we give the first approximation results in graphs that are not induced by unit ranges in the plane. We give a polynomial-time (Formula presented.)-approximation algorithm, where d̅ is the average degree and n the number of vertices in the graph, and show that the problem is Ω(n^1-ε)-hard (and Ω((dn)^1/2-ε)-hard) to approximate even on bipartite graphs, for any ε > 0, rendering our algorithm essentially optimal.
