Dynamic Bandwidth Allocation for Multi-Platform Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where a limited frequency band is allocated for controlling multiple mobile platforms, such as unmanned vehicles, ensuring sufficient bandwidth for each platform becomes a challenge, especially when the number of platforms increases, leading to communication interference and reduced operational efficiency.
Innovation Solution
An operating system that dynamically allocates bandwidth to channels based on mission priorities and performance information, allowing mobile platforms to request reallocation, thereby optimizing bandwidth usage across multiple channels and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of mobile platforms to be controlled is increased, then the system's operational capability is improved, but sufficient bandwidth cannot be provided for every mobile platform
Solution Approach 1:
The patent implements dynamic bandwidth allocation where the operating terminal continuously adjusts bandwidth distribution to mobile platforms based on real-time mission requirements and performance information. This dynamic adjustment allows the system to accommodate more mobile platforms by allocating bandwidth flexibly rather than using fixed allocation, resolving the contradiction between increased platform quantity and sufficient bandwidth provision.
Solution Approach 2:
The system changes the bandwidth parameter dynamically based on mission types, driving modes, and event occurrences. By adjusting bandwidth allocation parameters according to varying operational conditions, the system can efficiently serve more mobile platforms within the limited frequency band, addressing the bandwidth insufficiency problem when controlling multiple platforms.
2Ease of operation
If bandwidth is divided into N channels for N mobile platforms, then each platform receives allocated bandwidth, but communication interference occurs when the number of platforms is large
Solution Approach 1:
The patent employs feedback mechanisms where mobile platforms send performance information back to the operating terminal, which then adjusts bandwidth allocation accordingly. This closed-loop feedback system helps optimize channel usage and reduce communication interference by adapting to actual platform performance and channel conditions, allowing more platforms to operate simultaneously with reduced interference.
3Device complexity
If fixed bandwidth allocation is used for each channel, then bandwidth management is simplified, but bandwidth cannot be efficiently utilized when mission requirements vary
Solution Approach 1:
The system transitions from fixed to dynamic bandwidth allocation, where the operating terminal adjusts bandwidth in real-time based on mission requirements and platform performance. This dynamic approach increases bandwidth utilization efficiency without significantly increasing system complexity, as the allocation is automated based on predefined criteria and feedback loops.
