Maintenance of RSLN enabled PAN (I) maintenance features maintain time synchronization maintain repeaters on the path maintain end points originating source of time information comes from the PAN coordinator keep phasing between inner and outer coordinator’s time measure the off-phase by regressing the difference between the estimated time of event and the occurred time of event time-stamping for measuring the clock drift rate compensate clock drift periodically

Maintenance of RSLN enabled PAN (II) maintain relaying path status on the path link quality: inward, outward depth of relaying, repeater information on the path status of the repeater load status: how many end-points are connected status of the device check in-service power management control the transmission power

RSLN Synchronization time synchronization synchronize with the global time source phase to the inner coordinator cyclic-superframe beacon use the first time-stamp infor in any of frames from the inner coordinator compensate clock drift measure the off-phase explicit time information : time-stamp in beacon or management frame implicit time information : ACK time-stamp regress the clock drifting & update clock

Relaying Path Management (I) components of path management device address device type : PAN coordinator, repeater, end-point position on the path : relaying tier identifier, inward connected device, outward connected device link connection infor inside device infor: address, relaying tier identifier, device type, inside device’s cyclic-superframe beacon index outside device infor: address, relaying tier identifier, device type, outside device’s cyclic-superframe beacon index link quality inward link quality outward link quality path list of repeater list of end points status propagation delay, traffic

Relaying Path Management (II) one-hop link management connection infor link quality beacon bitmap list of active bidirectional device slots power management end-to-end path management check active end points propagation delay

Relaying Path Management (III) slot access for exchanging management infor broadcasting coordinator slot outward only 1-to-1 bidirectional device slot inward or outward one-hop link management or end-to-end path management management primitives & commands information vs control one-hop vs end-to-end
