Adaptive Vehicle Relay Control for Faster Data Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content distribution and data collection systems using device-to-device communication face challenges in areas of low vehicle density or non-peak traffic periods, where the number of distribution vehicles is difficult to increase, leading to prolonged data alignment times due to limited opportunities for data exchange and increased communication costs.
Innovation Solution
An information processing device that adjusts the number of mobile bodies participating in data relay by designating additional mobile bodies as relay vehicles through device-to-device communication when the total number falls below a threshold, enhancing data exchange opportunities without relying on cellular networks.

Engineering Contradiction Analysis
1Productivity
If the number of distribution vehicles is increased to reduce data alignment time, then content distribution speed is improved, but communication costs increase and device complexity increases
Solution Approach 1:
The system dynamically adjusts the number of distribution vehicles based on real-time conditions. When vehicle density is low or during non-peak periods, the system designates additional mobile bodies as relay vehicles to maintain sufficient distribution nodes. This dynamic adaptation allows the system to optimize between communication costs and distribution speed without committing to a fixed high number of vehicles always.
Solution Approach 2:
The system changes the parameter of 'number of distribution vehicles' based on detected conditions such as vehicle density and traffic period. By monitoring these parameters and adjusting the number of active distribution vehicles accordingly, the system achieves cost-effective operation while maintaining acceptable distribution performance.
2Productivity
If the number of distribution vehicles is increased to reduce data alignment time, then content distribution speed is improved, but device complexity increases
Solution Approach 1:
The mobile body automatically performs detection of vehicle density and determination of whether to designate additional relay vehicles. The control unit autonomously manages the designation of mobile bodies as relay vehicles without requiring manual configuration or complex centralized control, thereby reducing system complexity while maintaining distribution speed.
Solution Approach 2:
The system preliminarily designates mobile bodies as relay vehicles before actual data distribution begins. This advance preparation ensures that when data alignment is needed, the relay vehicles are already in position and ready to facilitate quick data exchange, reducing the overall time required without adding operational complexity during the distribution process.
3Loss of time
If relay vehicles are designated to increase data exchange opportunities, then data alignment time is reduced, but the number of communication connections increases
Solution Approach 1:
The system segments the data distribution task by designating specific mobile bodies as relay vehicles with particular responsibilities. Each relay vehicle handles specific data exchange tasks, which organizes the communication connections into manageable segments rather than requiring all vehicles to maintain connections with all other vehicles, thereby reducing overall connection complexity.

AI summary
An information processing device acquires a total number of second mobile bodies and third mobile bodies within a predetermined area, the second mobile bodies relays a data block between a first mobile body and a predetermined server through device-to-device communication with the first mobile body and through first wireless communication with the predetermined server, and the third mobile bodies relays the data block between the first mobile body and the second mobile bodies through the device-to-device communication. When the total number of second mobile bodies and third mobile bodies is less than a predetermined threshold value, the information processing device instructs either the second mobile bodies or the first mobile body to appoint a different mobile body as a third mobile body by transmitting the data block to the different mobile body through the device-to-device communication.
