PIB Attribute Coordination in 802.15.4g May 2010 PIB Attribute Coordination in 802.15.4g Taylor [DTC (UK)], Gilb [SiBeam]

doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> May 2010 Issues Various 15.4g PHY operations require that Tx & Rx device have coordinated PIB attribute values Furthermore, since some proposed parameters exchange index values into PIB attribute sets, the order of the PIB attributes is significant Some PIB attributes may be changed during 15.4g network operation and these changes need to be coordinated Taylor [DTC (UK)], Gilb [SiBeam] <author>, <company>

May 2010 Possible Solutions If 15.4g networks should be statically configured, then text should be added to explain the configuration and its relationship to network formation and device operation An upper layer network management protocol can be referenced as a required (normative) reference e.g. SNMP However, SNMP requires the definition and compilation of a MIB – a non-trivial task Define MAC layer enhancements to allow coordinated exchange of those parameters needed for 15.4g operation Taylor [DTC (UK)], Gilb [SiBeam]

MAC layer enhancements May 2010 MAC layer enhancements Need to operate in both beacon and non-beacon modes Probably require a probe/response procedure and associated MAC Command frames Need to determine those PIB attributes that must be managed However, there may be further issues with error recovery and time sequence in this procedure Taylor [DTC (UK)], Gilb [SiBeam]
