Edge-assisted Data Transmission For Connected Vehicles
In an example embodiment, a method receives a first request of a first vehicle for a content item; receives travel data of the first vehicle including a first vehicle route of the first vehicle; determines first edge server(s) located on the first vehicle route of the first vehicle; segments the content item into content segment(s) based on the travel data of the first vehicle and edge information of each first edge server; and dispatches each content segment to the corresponding first edge server for transmission to the first vehicle.

- 1. A method comprising:
receiving a first request of a first vehicle for a content item; receiving travel data of the first vehicle including a first vehicle route of the first vehicle; determining one or more first edge servers located on the first vehicle route of the first vehicle; segmenting the content item into one or more content segments based on the travel data of the first vehicle and edge information of each first edge server; and dispatching each content segment to the corresponding first edge server for transmission to the first vehicle.
- 13. A method comprising:
receiving by an edge server, from a management server, a content segment of a content item requested by a first vehicle; determining, by the edge server, one or more performance metrics of the edge server; computing, by the edge server, a target transmission data rate for the content segment based on the one or more performance metrics of the edge server; adaptively encoding, by the edge server, the content segment using the target transmission data rate to generate an encoded content segment; receiving, by the edge server, a connection request from the first vehicle; and responsive to receiving the connection request from the first vehicle, transmitting, by the edge server, the encoded content segment to the first vehicle.
- 20. A system comprising:
one or more processors; one or more memories storing instructions that, when executed by the one or more processors, cause the system to:
receive a first request of a first vehicle for a content item;
receive travel data of the first vehicle including a first vehicle route of the first vehicle;
determine one or more first edge servers located on the first vehicle route of the first vehicle;
segment the content item into one or more content segments based on the travel data of the first vehicle and edge information of each first edge server; and
dispatch each content segment to the corresponding first edge server for transmission to the first vehicle.
- 29. A system comprising:
one or more processors; one or more memories storing instructions that, when executed by the one or more processors, cause the system to:
receive, from a management server, a content segment of a content item requested by a first vehicle;
determine one or more performance metrics of the system;
compute a target transmission data rate for the content segment based on the one or more performance metrics of the system;
adaptively encode the content segment using the target transmission data rate to generate an encoded content segment;
receive a connection request from the first vehicle; and
responsive to receiving the connection request from the first vehicle, transmit the encoded content segment to the first vehicle.
