Relay Vehicle Selection for V2X Message Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the Internet of Vehicles, the widespread use of broadcast messages for V2X communication leads to severe interference and redundancy, with vehicles unsure if their messages are successfully transmitted and the network load unknown, and multi-hop transmission not supported, resulting in limited message coverage.
Innovation Solution
An electronic device and wireless communication method that determine and include information about relay vehicles in vehicle-related messages, allowing only designated relay vehicles to forward messages, thereby reducing redundancy and interference, and enabling multi-hop transmission to expand message coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If all vehicles forward broadcast messages, then message coverage is expanded, but transmission redundancy and interference increase
Solution Approach 1:
The patent segments the message forwarding function by introducing a relay vehicle selection mechanism. Instead of all vehicles forwarding messages, only selected relay vehicles (determined by ID comparison and random selection) forward messages. This segmentation reduces the number of forwarding nodes, thereby reducing interference and redundancy while maintaining message coverage through multi-hop transmission.
2Speed
If broadcast mode is used for V2X communication, then real-time message transmission is achieved, but network overhead increases and interference worsens
Solution Approach 1:
The patent extracts the message forwarding function from all vehicles and concentrates it on selected relay vehicles only. By taking out the forwarding responsibility from the general vehicle population and assigning it selectively, the system reduces the quantity of signaling overhead and interference-generating transmissions while preserving real-time message delivery capability.
3Area of stationary object
If multi-hop transmission is not supported, then system complexity is reduced, but message coverage is limited
Solution Approach 1:
The patent implements preliminary action by pre-selecting relay vehicles and embedding their information in messages before transmission. This allows multi-hop transmission to occur automatically as messages pass through predetermined relay nodes, expanding message coverage without requiring complex real-time routing decisions at each hop, thus managing system complexity effectively.
