Communications Management Module for Moving Platforms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing wireless communications between moving platforms and target nodes are inadequate in responding to unexpected events like link failures, leading to data loss and buffer overflow due to continuous data transmission without considering network conditions.
Innovation Solution
A communications management system with a data management module that classifies and prioritizes platform application data, determines actions based on stored rules, and generates control signals to store or discard data accordingly, adapting to available communication links and network conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If continuous data transmission is performed without considering network conditions, then data transmission throughput is maintained, but buffer overflow and data loss occur during link failures
Solution Approach 1:
The system continuously monitors network conditions and uses this feedback to dynamically adjust transmission behavior. The data management module receives network status information and modifies data handling actions accordingly, creating a closed-loop control system that prevents buffer overflow while maintaining throughput during normal operation
Solution Approach 2:
The system transitions from static continuous transmission to dynamic adaptive transmission. The data management module changes transmission behavior based on real-time network conditions, switching between storing, discarding, and transmitting data according to the current link status and data priority
2Loss of information
If critical information is stored during link failures for later transmission, then information completeness is improved, but storage resources and transmission time are consumed
Solution Approach 1:
The system changes the state parameter of data from 'transmitted' to 'stored' based on network conditions. By modifying the data status parameter dynamically, the system preserves critical information during link failures and restores transmission when conditions improve, balancing information completeness with transmission timing
3Reliability
If a data management module is introduced to classify and manage data transmission, then data delivery reliability is improved, but system complexity increases
Solution Approach 1:
The system segments data into different priority levels (critical and non-critical) and applies different handling rules to each segment. This segmentation allows the data management module to make targeted decisions for different data types, improving reliability without requiring complex centralized control for all data
