Patent number: 11272423Abstract: A multi-hop relay network comprises a set of data nodes arranged in a relay topology, wherein the set of data nodes communicate with one another via a data plane comprising a set of high frequency data links, such as mmWave links. An edge node communicates with one or more of the set of data nodes via the data plane and communicates with the set of data nodes over a control plane comprising a set of low frequency wireless links, such as a Wi-Fi network. The edge node determines a path utilization for the set of high frequency wireless links. When one of the high frequency wireless links is over-utilized, the edge node communicates, to a data node in the set of data nodes via the control plane, a command to change the relay topology. The edge node also determines whether the relay topology is operating at a target accuracy. When it is not, the edge node adjusts a data analytics parameter for a node to improve the overall accuracy of the network.Type: GrantFiled: April 29, 2020Date of Patent: March 8, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Ganesh Ananthanarayanan, Yuanchao Shu, Paramvir Bahl, Longfei Shangguan, Zhuqi Li
