ISO/IEC DIS 17821

Description / Abstract: This standard 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 standard provides the followings:

• 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
