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 ...
MERLIN : cross-layer integration of MAC and routing for low duty-cycle sensor networks

Ruzzelli, Antonio G. ; O'Hare, G. M. P. (Greg M. P.) ; Jurdak, Raja (Elsevier, 2008-11)

Sensor network MAC protocols typically sacrifice packet latency to achieve energy efficiency. Such delays may well increase due to routing protocol operation. For this reason it is imperative that we attempt to quantify ...
