Abstract: Various embodiments disclosed herein provide communication techniques for transferring datasets in a mesh network. In various embodiments, a method includes transmitting, by a server computing device controlling a mesh network, a dataset to a first node in the mesh network; transmitting, by the server computing device, first notifications to respective second nodes that are neighbors to the first node in the mesh network, the first notifications informing the respective second nodes that the dataset is available for download; and in response to determining that a third node from the respective second nodes has received the dataset, transmitting, by the server computing device, second notifications to respective fourth nodes that are neighbors to the first node in the mesh network or are neighbors to the third node in the mesh network, the second notifications informing the respective fourth nodes that the dataset is available for download.

Abstract: Various embodiments disclose a method that includes: attempting to detect, with a first transceiver associated with a first node, a network discovery signal, wherein the attempting is performed according to (a) a first listening schedule associated with a first physical layer mode and (b) a second listening schedule associated with a second physical layer mode; detecting, with the first transceiver, the network discovery signal during a slot associated with the first listening schedule; and in response to detecting the network discovery signal, establishing, with the first node, a connection between the first node and the second node using the first physical layer mode.

Abstract: Various embodiments disclose techniques for time-multiplexing multiple listening schedules and physical layer modes that include a first node listening, using a first physical layer mode, for a first network discovery signal; in response to not detecting the first network discovery signal, listening, using a second physical layer mode, for a second network discovery signal; and in response to detecting the second network discovery signal transmitted by a second node using the second physical layer mode, establishing a connection with the second node using the second physical layer mode.

Abstract: Techniques for managing multi-mode communications between nodes in a network include initiating, by a first node in a mesh network, a carrier sense multiple access with collision avoidance (CSMA/CA) session while the first node is in a first mode. The CSMA/CA session is associated with a request to transmit a data message to a second node in the mesh network. Initiating the CSMA/CA session includes determining availability of a channel associated with a channel schedule of the second node associated with the first mode.
