  4. Subgroup Members • Greg Gillooly (Aclara, Liaison of 4g) • Zafer Sahinoglu (MERL, assigned editor) • Mike McInnis (Boeing) • Rene Struik (Certicom) • Ben Rolfe (Blind Creek) • Betty Zhao (Hua Wei) • Liang Li (Vinno, Chinese WPAN) • Corné van Puijenbroek (Nanotron) • Barbara Staehle (UniWuerzburg) • Michael Bahr (Siemens) • Kris Pister (UC Berkeley, Dust Networks) • David Culler (UC Berkeley, Arch Rock) • Jonathan Hui (Arch Rock) • ETGS Wei Hong, Arch Rock Corporation

  5. Progress To Date • May 2008 (JAX) Application Requirements • July 2008 (DEN) Preliminary Proposal • Sept 2008 (KOA) Final Proposal • Nov 2008 (DFW) Proposal Review • Mar 2009 (YVR) Proposal Extended with HuaWei and Vinno’s low-energy association proposal • May 2009 (YUL) Draft changes to 15.4 2006 reviewed and approved as baseline • https://mentor.ieee.org/802.15/dcn/09/15-09-0427-02-004e-draft-low-energy-amendment-to-802-15-4-mac.doc Wei Hong, Arch Rock Corporation

  6. Subgroup Discussions • 20-year battery lifetime (feedback from 4g) • No need for sampled listening if routing nodes are always on • Endpoint nodes keep radio off until transmission time • Fast association (feedback from 4f) • Michael McInnis’ “Blink” • Out of scope for low-energy proposal • Drafting low-energy association changes • Resolved differences with HuaWei • No need to introduce new MLME primitives Wei Hong, Arch Rock Corporation
