Abstract

A method of beam-based communication amongst a plurality of network nodes comprises detecting, by a subject node, a presence of a first set of nodes for beam-based communication, and receiving a list of a second set of nodes from at least a first node of the first set of nodes. Further, the method includes identifying at least a second node in the second set of nodes that is not detectable for beam-based communication by the subject node. The method comprises generating a distance-based mapping including distance information relating to the first set of nodes and the second node, from the subject node. Further, the method comprises transmitting, via beam-based communication by the subject node, content to a destination node based on a communication path determined using the distance-based mapping, the destination node being a node of one of the first set of nodes and the at least second node.

First claim

What is claimed is:

1. A method of beam-based communication amongst a plurality of network nodes, the method comprising:
detecting, by a subject node, a presence of a first set of nodes for beam-based communication;
requesting, by the subject node to the first set of nodes, a list of a second set of nodes;
acquiring the list of the second set of nodes from a first node of the first set of nodes, wherein the second set of nodes is detected from the first node by performing beam-based communication, and the list of the second set of nodes includes a physical distance of each node of the second set of nodes from the first node of the first set of nodes;
identifying a second node in the second set of nodes that is not detectable for beam-based communication by the subject node;
determining an arrangement of the first set of nodes and the second set of nodes in ascending order of physical distance from the subject node;
generating a distance-based mapping including physical distance information using the list of the second set of nodes acquired from the first node of the first set of nodes;
determining one or more nodes present between the subject node and a destination node based on the distance-based mapping;
determining a first communication path including the one or more nodes, that are arranged in ascending order of distances from the subject node;
transmitting content to the destination node based on the first communication path,
wherein the destination node includes at least one of the first set of nodes or the second set of nodes;
determining a movement of at least one node of the one or more nodes;
updating, based on the movement, the distance-based mapping;
determining, based on the updated distance-based mapping, a second communication path including the one or more nodes;
transmitting content to the destination node based on the second communication path;
receiving, by the subject node, from a node located in front of the subject node, a first map indicating a first travel route for the subject node;
generating, by the subject node, based on the distance-based mapping, a second map indicating a second travel route for a node located behind the subject node; and
transmitting, by the subject node, the second map to the node located behind the subject node,
wherein the first travel route for the node located behind the subject node is different than the second travel route for the subject node,
wherein the plurality of network nodes are a group of vehicles traveling on multiple lanes of a road, and
wherein the first travel route and the second travel route are based on a traffic density of the lanes.

2. The method as claimed in claim 1 , wherein the step of transmitting further comprises:
forming a beam-based communication link with a first node of the communication path; and
transmitting the content or destination information of the destination node to the first node of the communication path, wherein the destination information includes an identity of the destination node and instructions to transmit the content to the destination node.

3. The method as claimed in claim 2 , further comprising:
determining non-availability of the destination node for beam-based communication with the first node of the communication path;
identifying a second node of the communication path that is available for beam-based communication with the first node of the communication path;
forming a link with the second node of the communication path; and
transmitting the content or the information to the second node of the communication path.

4. The method as claimed in claim 1 , wherein the list of the second set of nodes further comprises information about a relative distance of the second set of nodes from the first node.

5. The method as claimed in claim 4 , wherein the relative distance is calculated about the first node.

6. The method of claim 4 , further comprising generating the distance-based mapping based on a relative distance of each of the first set of nodes from the subject node and the list of the second set of nodes.

7. The method as claimed in claim 6 , further comprising:
calculating the relative distance between the subject node and each of the first set of nodes, wherein the relative distance between the subject node and a node from the first set of nodes is determined based on a speed of the subject node, a speed of the node, a serving beam angle between the subject node and the node.

8. The method as claimed in claim 1 , further comprising:
detecting, during the transmission of the content, the second node to be within a threshold distance from the subject node;
establishing a beam-based communication link with the second node, in response to detecting the second node to be within the threshold distance from the subject node; and
terminating the beam-based communication link with the first node, after successful establishment of the beam-based communication link with the second node.

9. A subject node configured to perform beam-based communication with a plurality of network nodes, the subject node comprising:
communication circuitry;
at least one processor; and
memory for storing instructions that, when executed by the at least one processor individually or collectively, cause the subject node to:
detect a presence of a first set of nodes for beam-based communication, wherein to detect the presence of the first set of nodes, the instructions cause the subject node to, for each node of the first set of nodes:
request, by the subject node, to the first set of nodes, a list of a second set of nodes;
acquire the list of the second set of nodes from a first node of the first set of nodes, wherein the second set of nodes is detected from the first node by performing beam-based communication, and the list of the second set of nodes includes a physical distance of each node of the second set of nodes from the first node of the first set of nodes;
identify a second node in the second set of nodes that is not detectable for beam-based communication by the subject node;
determine an arrangement of the first set of nodes and the second set of nodes in ascending order of physical distance from the subject node;
generate a distance-based mapping including physical distance information using the list of the second set of nodes acquired from the first node of the first set of nodes;
determine one or more nodes present between the subject node and a destination node based on the distance-based mapping;
determine a communication path including the one or more nodes, that are arranged in ascending order of distances from the subject node;
transmit, via beam-based communication by the subject node, content to the destination node based on the communication path, wherein the destination node includes at least one of the first set of nodes or the second set of nodes;
determine a movement of at least one node of the one or more nodes;
update, based on the movement, the distance-based mapping;
determine, based on the updated distance-based mapping, a second communication path including the one or more nodes;
transmit content to the destination node based on the second communication path;
receive, from a node located in front of the subject node, a first map indicating a travel route for the subject node;
generate, based on the distance-based mapping, a second map indicating a travel route for a node located behind the subject node; and
transmit the second map to the node located behind the subject node,
wherein the first travel route for the node located behind the subject node is different than the second travel route for the subject node,
wherein the plurality of network nodes are a gro
