Abstract

In this paper, we propose a new distributed algorithm that constructs a sparse spanner subgraph of the unit disk graph efficiently for wireless ad hoc networks. It maintains a linear number of links while still preserving some power-efficient routes for any pair of nodes. We prove that this new topology not only has a bounded node degree k but also has a bounded power stretch factor 2 in civilized graph. Finally, we give some simulation results to verify its performance in practice and conclude the paper with the discussion of possible future works.
