Span: An Energy-Efficient Coordination Algorithm for Topology Maintenance in Ad Hoc Wireless Networks

by Benjie Chen. Kyle Jamieson. Hari Balakrishnan. Robert Morris.

This paper presents Span, a power saving technique for multi-hop ad hoc wireless networks that reduces energy consumption without significantly deminishing the capacity or connectivity of the network. Span builds on the observation that when a region of a shared-channel wireless network has a sufficient density of nodes, only a small number of them need be on at any time to forward traffic for active connections.
