Publication number: 20230199610Abstract: Techniques and devices for determining a preferred physical layer for communication by a node in a Thread network are described. The node transmits a first IPv6 over Low power Wireless Personal Area Networks, 6LoWPAN, frame to a neighbor node using a first physical layer and transmits the first 6LoWPAN frame to the neighbor node using a second physical layer. The node determines a first preference value for the neighbor node using the first physical layer and determines a second preference value for the neighbor node using the second physical layer. The node compares the first preference value and the second preference value to determine the preferred physical layer for communication and transmits a second 6LoWPAN frame to the neighbor node using the preferred physical layer.Type: ApplicationFiled: May 14, 2021Publication date: June 22, 2023Applicant: Google LLCInventors: Jonathan Wing-Yan Hui, Abtin Keshavarzian, Matt Daniel Smith, Yakun Xu

Patent number: 9202369Abstract: A method of wireless communication includes providing a matrix of trackers. The matrix includes rows and columns of trackers. A number of rows and a number of columns in the matrix is determined. If the number of rows is substantially greater than the number of columns, then vertical sweeping is performed including passing data along each of the columns of trackers to an end tracker in each column. If the number of rows is substantially less than the number of columns, then horizontal sweeping is performed including passing data along each of the rows of trackers to an end tracker in each row. If the number of rows is substantially equal to the number of columns, then diagonal sweeping is performed including passing data diagonally across each of the rows and columns of trackers to an end tracker in each row and each column. The data is passed along the end trackers to a final destination data collector.Type: GrantFiled: July 17, 2012Date of Patent: December 1, 2015Assignee: Robert Bosch GmbHInventors: Vivek Jain, Gunther May, Lakshmi Venkatraman, Abtin Keshavarzian, Till Deubel
