Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless multipath transmission methods face challenges in efficiently distributing data packets across different links due to unpredictable link statuses and dynamic bandwidth allocation, leading to reduced throughput and increased delay, with potential data transmission failures when links fail.
Innovation Solution
Encoding original data packets into a greater number of encoded packets, which are then transmitted through various links, allowing the receiving end to decode and reconstruct the original packets, while considering link status and bandwidth for optimal distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data packets are distributed across multiple transmission links, then data transmission reliability is improved, but transmission delay increases due to unpredictable link statuses and dynamic bandwidth allocation
Solution Approach 1:
The patent applies preliminary action by performing encoding of original data packets into encoded data packets before transmission. This preprocessing step ensures that even if some transmission links fail or experience delays, the receiving end can reconstruct the original data from the encoded packets received through available links, thereby reducing the impact of transmission delays while maintaining reliability
Solution Approach 2:
The patent changes the parameter of data packet structure by encoding original data packets into multiple encoded data packets with different characteristics. This transformation allows the system to adapt to varying link conditions by distributing encoded packets across multiple links with different bandwidths and reliability levels, optimizing the trade-off between transmission reliability and delay
2Reliability
If encoded data packets are transmitted through multiple links, then data integrity is improved, but system complexity increases due to encoding and decoding operations
Solution Approach 1:
The patent introduces encoding and decoding as intermediary processes between the transmitting and receiving ends. These intermediaries transform original data packets into encoded form for transmission and reconstruct them at the receiving end, ensuring data integrity while managing complexity through standardized encoding/decoding operations that can be implemented using established error correction codes
Solution Approach 2:
The patent segments original data packets into multiple encoded data packets for distribution across different transmission links. This segmentation allows the system to achieve data integrity through redundancy while managing complexity by dividing the transmission task into independent packet segments that can be processed and transmitted separately
3Productivity
If link resources are efficiently utilized through encoding, then throughput is improved, but transmission delay increases due to encoding processing time
Solution Approach 1:
The patent performs encoding as a preliminary action before data transmission, allowing the encoding process to be completed in advance and the encoded packets to be ready for immediate transmission. This reduces the impact of encoding processing time on overall transmission delay while maximizing throughput by having encoded packets ready for efficient distribution across multiple links
