A method for selecting at least one gateway in a set of gateways for relaying data received from a server and intended for each endpoint in a group of endpoints, each endpoint in group communicating with the server via at least one gateway in the set of gateways, the group of endpoints and the set of gateways forming a LoRa network, each gateway receiving data intended for at least one endpoint retransmitting data to each endpoint for which data are intended in a frame in accordance with the LoRaWAN protocol. The method includes: selecting a subset of gateways of the set of gateways enabling the server to communicate with each endpoint group of minimum size, the selected subset minimising a risk of the data sent by the server and relayed by each gateway of subset being lost because of collisions between frames relaying data sent by the gateways of subset.

In one embodiment, a method comprises: identifying, by a low power and lossy network (LLN) device in a low power and lossy network, a minimum distance value and a distance limit value for limiting multicast propagation, initiated at the LLN device, of a multicast data message in the LLN; and multicast transmitting, by the LLN device, the multicast data message with a current distance field specifying the minimum distance value and a distance limit field specifying the distance limit value, the multicast transmitting causing a receiving LLN device having a corresponding rank in the LLN to respond to the multicast data message by: (1) determining an updated distance based on adding to the current distance field a rank difference between the receiving LLN device and the LLN device, and (2) selectively retransmitting the multicast data message if the updated distance is less than the distance limit value.

A method for terminal clustering in a wireless communication system supporting D2D (Device-to-Device) communication and an apparatus supporting the method are disclosed. More specifically, a method for a user equipment (UE) to perform UE clustering in a wireless communication system supporting D2D communication comprises determining an initial preference value, determining an initial preference triplet by performing an AP (Affinity Propagation) method by increasing or decreasing the preference value, updating a preference triplet through a GSS (Golden Section Search) method based on the initial preference triplet, determining a final preference value for minimizing energy consumption of the entire UEs from the updated preference triplet; and determining a head UE and member UEs belonging to the head UE by performing the AP method by using the final preference value.

A more efficient network is facilitated by data routing. A node device within a network can broadcast a first set of data to a network of other node devices. Based on node device characteristics, some nodes will hear the broadcast first and can be labeled as a relay node. The relay nodes can then transmit other data based on the determination of other relay nodes.

The present disclosure is related to systems, methods, and processor readable media for distributing digital data over networks. Certain embodiments relate to systems, methods, and devices used within such networks where at least a substantial portion of the interconnected devices are capable of interacting with one or more neighbouring devices, and then to form such a time synchronous network using local network information.

An information processing apparatus in a mesh network, includes circuitry that, when the information processing apparatus is allocated as a root node for multicast transmission, transmits path request for multicast to other information processing apparatuses in the mesh network. The circuitry also determines a path for multicast based on responses received from the other information processing apparatuses, and performs multicast transmission of data via the determined path for multicast.
