Aggregated Vehicle Data Links via P2P Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected cars face limitations in performance due to the use of a single independent wireless data link for communication, which can restrict data-intensive applications and lead to poor quality of service, especially when individual links are disconnected or have poor efficiency.
Innovation Solution
The implementation of a peer-to-peer (P2P) network that aggregates multiple wireless communication links within a connected vehicle, creating a single, faster data pipe shared among user equipment, utilizing a local platform device to manage and control the P2P network without modifying existing hardware or software, and employing virtual machines and trackers for efficient data routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple independent wireless data links are available in connected cars, then communication capacity and data speed should be improved, but utilizing only one link limits performance of data-intensive applications
Solution Approach 1:
The patent merges multiple independent wireless data links (cellular, WiFi, Bluetooth) into a unified communication interface through software-based link aggregation. The system combines available links from various devices in the vehicle to create a single high-capacity data pipe, enabling data-intensive applications to utilize the aggregate bandwidth of all available links simultaneously.
Solution Approach 2:
The communication system is designed to universally support multiple wireless link types (cellular, WiFi, Bluetooth) and dynamically select or combine them based on availability and requirements. Each device in the vehicle can contribute different link types, and the system adapts to utilize any combination of these links for optimal performance.
2Reliability
If a single wireless data link is used for communication, then device complexity is reduced, but quality of service deteriorates when the link is disconnected or has poor efficiency
Solution Approach 1:
The system establishes backup communication paths in advance by maintaining multiple wireless links simultaneously. When the primary link deteriorates or disconnects, alternative links are already available to immediately take over, preventing service interruption. This cushioning effect ensures continuous communication without requiring complex real-time switching decisions.
Solution Approach 2:
A software-based aggregation layer acts as an intermediary between applications and physical wireless links. This intermediary manages link selection, combination, and failover transparently, shielding applications from the complexity of multiple link management while providing reliable communication services.
3Productivity
If data-intensive applications require high bandwidth, then communication performance should be improved, but single link capacity becomes insufficient
Solution Approach 1:
The system combines the bandwidth capacity of multiple wireless links (cellular, WiFi, Bluetooth) to create an aggregate data pipe with sufficient capacity for data-intensive applications. By merging links in parallel, the available bandwidth is multiplied, enabling high-performance applications without requiring a single high-capacity link.

AI summary
Connected cars are coupled to several communication devices (e.g., embedded devices and/or user equipment (UE) of occupants of the car) having independent data links to a communication network (e.g., cellular network). Peer-to-peer (P2P) protocols can be employed to consolidate and aggregate multiple data links within the car to create an aggregated data link that is shared by the devices. During initialization, a local platform device within the connected car sets up a local tracker and communicates with a backend network device to setup a corresponding remote tracker. The trackers generate virtual data nodes corresponding to the communication devices and facilitate communication between the virtual data nodes and the devices via P2P protocols. Moreover, the P2P protocol technology is overlaid on the application layers of the communication devices without modifications to the devices' hardware and software construction.
