信息技术.信道跳变TDMA链路上的低功率无线网状网络规范

[中文适用范围]： 本国际标准定义了在IEEE Std. 802.15.4-2011 PHY上运行的设备的网络规范，能够支持IEEE Std. 802.15.4e-2012的DSME MAC的信道跳变TDMA链路，以提供低成本通信网络，允许可靠、确定性延迟和可扩展的无线网状连接。本国际标准提供以下内容：— DSME MAC链路控制；— 基于不平衡簇树的网络形成；— 定向多级网状连接；— 链路路径路由和数据转发；— 链路和链路路径维护。 [外文原描述]： 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.
