The proposed mode utilizes a Synchronous Low Power Listening technique that allows nodes to sleep for multiple Beacon Intervals and subsequently recover Beacon synchronization in a power efficient manner. The proposed mode also incorporates a Periodic Wakeup scheme that allows nodes to transmit at scheduled times during the inactive period. The proposed Enhanced Mode is backward compatible and inter-operable with the original standard. Simulation results show that the proposed Enhanced Mode reduces the power consumption overhead of synchronization by more than 50% for applications with low data rates compared with standard Beacon-Enabled mode. End-to-end delay and packet loss rate are reduced by more than 90% compared with standard Beacon-Enabled mode. The proposal can adapt to the change of traffic load, and prolong the lifetime of the PAN Coordinator by 1–5 times compared to standard Beacon Enabled mode.||Funding Details:||Enterprise Ireland||Type of material:||Journal Article||Publisher:||Springer||Journal:||Wireless Networks||Volume:||18||Issue:||1||Start page:||59||End page:||74||Copyright (published version):||2011 Springer Science+Business Media, LLC||Keywords:||IEEE 802.15.4; Beacon-enabled mode; Power saving; Low power listening; Synchronization; MAC layer; Protocol design||DOI:||10.1007/s11276-011-0387-y||Language:||en||Status of Item:||Peer reviewed|
