Demand-Aware Plane Spanners of Bounded Degree

Demand-Aware Plane Spanners of Bounded Degree

Abstract

Plane spanners of bounded degree are efficient communication backbones for networks. However, while existing spanners provide attractive guarantees in the worst-case, they are demand-oblivious and may hence be suboptimal under specific traffic demands. This paper thus initiates the study of demand-aware plane spanners with bounded degree, geometric spanners whose topology accounts for the actual communication traffic. We show that demand-awareness can significantly reduce the distance travelled per bit, and present a spanner which exploits topological flexibilities to account for the demand, without losing the desirable guarantees of demand-oblivious spanners, namely constant stretch and degree. We complement our analytical results with further heuristic improvements and a simulation study exploring the benefits of demand-awareness under realistic traffic traces.
