ISO/IEC 17821 (2015-04)

ISO/IEC 17821:2015 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 communication 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.
