The common belief is that a multi-hop configuration with rather small per-hop distance is the only viable energy-efficient option for wireless sensor networks. We discuss a single hop configuration, utilizing the asymmetry between lightweight sensor nodes and a more powerful "base station" and demonstrate that such a single hop configuration can actually have lower overall power consumption than a multi-hop counterpart.
