State-of-the-art low-power transceivers for the next generation of wireless sensor networks motes

In this paper we evaluate capabilities of the last generation conunercial off-the-shelf low-power wireless communication transceivers for energy/spectrum-efficient transmission while satisfying quality of service requirements. We set ten appropriate criteria and select six transceivers to evaluate. We find that provided decision space regarding energy-efficiency at PHY/MAC layers is improved, compared to the previous generation of the transceivers, but an ample space for spectrum-efficiency improvement still exists.
