scope:

NEN-ISO/IEC 17821 defines the network specification for devices, which are operated on IEEE Std .802.15.4-2011 PHY capable to support the channel-hopped TDMA links of the DSME MAC of IEEE STD. 802.15.4E-2012, to provide low cost communicaton network that allows reliable, deterministic-latency, and scalable wireless mesh connectivity. This International Standard provides the following: - DSME MAC link control; - unbalanced cluster-tree based network formation; - directional multiple grades mesh connection; - link-path routing and data forwarding; - link and link-path maintenance.
