Coordinated sleeping for beaconless 802.15.4-based multihop networks

Ruzzelli, Antonio G. ; Schoofs, Anthony ; O'Hare, G. M. P. (Greg M. P.) ; Aoun, Marc ; Stok, Peter van der (Springer, 2009-09)

The last few years have seen a wide adoption of the IEEE 802.15.4 MAC/PHY standard for low-power communication between wireless sensor nodes. Within this work we study some fundamental drawbacks of the 802.15.4 specifications ...
Multi-hop RFID wake-up radio : design, evaluation and energy tradeoffs

Jurdak, Raja ; Ruzzelli, Antonio G. ; O'Hare, G. M. P. (Greg M. P.) (IEEE Press, 2008-08)

Energy efficiency is a central challenge in battery operated sensor networks. Current energy-efficient mechanisms employ either duty cycling, which reduces idle listening but does not eliminate it, or low power wake-up ...
