Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Vehicle-to-Everything (V2X) communication systems face interference and inefficiencies due to the uncoordinated use of cell-supported and adhoc radio communications networks, leading to data congestion and increased processing efforts in higher layer functions.
Innovation Solution
A roadside network node equipped with both cell-supported and adhoc radio modules, capable of coordinating the use of different access technology layers to reduce interference, perform traffic flow control, and determine optimal channels for data transmission based on similarity values, thereby aggregating and routing data efficiently across both networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uncoordinated use of cell-supported and adhoc radio communications networks is allowed, then device complexity is reduced, but interference and data congestion increase
Solution Approach 1:
The road-side network node acts as an intermediary between cell-supported and adhoc radio communications networks, coordinating data exchange between vehicles using different access technologies. The node manages channel selection and data routing to prevent interference while maintaining compatibility between the two network types.
Solution Approach 2:
The system dynamically selects between cell-supported and adhoc radio channels based on real-time conditions. The road-side network node adapts its operation mode and channel selection to optimize data transmission and minimize interference, rather than using a fixed coordination approach.
2Adaptability or versatility
If data is transmitted through multiple access technology layers without coordination, then adaptability is improved, but processing effort and congestion increase
Solution Approach 1:
The road-side network node performs preliminary channel selection and data routing decisions before data transmission occurs. By evaluating channel conditions and determining optimal paths in advance, the system reduces real-time processing effort and prevents data congestion while maintaining adaptability.
Solution Approach 2:
The system merges data from both cell-supported and adhoc networks at the road-side network node, consolidating duplicate data and optimizing the combined data stream. This reduces redundant processing and improves overall data transmission efficiency.
3Adaptability or versatility
If both cell-supported and adhoc radio modules are deployed, then versatility is improved, but device complexity increases
Solution Approach 1:
The road-side network node is designed with multi-functionality, supporting both cell-supported and adhoc radio communications networks simultaneously. This universal design allows a single node to serve multiple communication purposes, reducing the need for separate dedicated nodes for each network type.
Data Source
AI summary
A first road-side network node for operating in a cell-supported radio communications network and for operating in an adhoc radio communications network is provided. Data is exchanged with at least a second road-side network node via a sidelink radio channel of the cell-supported radio communications network. Data is exchanged with at least a third road-side network node via an adhoc radio channel of the adhoc radio communications network.
