A-MSDU Aggregation via Receiver Address Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for generating Aggregated Media Access Control Service Data Units (A-MSDUs) do not provide a clear method for improving MAC efficiency, particularly in generating these units efficiently across wireless networks with error-prone channels and varying frame sizes.
Innovation Solution
A method for generating A-MSDUs involves re-grouping incoming frames by their receiver addresses during the aggregation process, allowing for larger aggregate sizes and reduced interruptions, while maintaining time ordering and handling frame processing and encryption efficiently to minimize clock cycles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If frames are aggregated without re-grouping by receiver address, then the aggregation process is simpler, but the aggregate size is smaller and interruptions occur more frequently
Solution Approach 1:
The patent applies preliminary action by re-grouping incoming frames by receiver address before aggregation. This pre-organization of frames ensures that all frames destined for the same receiver are collected together, enabling larger aggregate sizes and reducing interruptions during the aggregation process, thereby improving network throughput.
Solution Approach 2:
The patent applies segmentation by organizing frames into separate groups based on their receiver addresses. This segmentation allows the aggregation process to handle frames destined for different receivers independently, creating more efficient aggregates while maintaining the ability to process multiple receiver streams simultaneously.
2Productivity
If frame aggregation is implemented to improve MAC efficiency, then throughput increases, but handling frames with different receiver addresses becomes more complex
Solution Approach 1:
The patent applies preliminary action by re-grouping incoming frames by receiver address before aggregation. This pre-organization of frames ensures that all frames destined for the same receiver are collected together, enabling larger aggregate sizes and reducing interruptions during the aggregation process, thereby improving network throughput.
Solution Approach 2:
The patent applies segmentation by organizing frames into separate groups based on their receiver addresses. This segmentation allows the aggregation process to handle frames destined for different receivers independently, creating more efficient aggregates while maintaining the ability to process multiple receiver streams simultaneously.
3Reliability
If encryption is performed on each frame individually, then security is maintained, but processing time and clock cycles increase
Solution Approach 1:
The patent applies merging by combining multiple frames destined for the same receiver into a single aggregate frame before encryption. This approach maintains security by encrypting the aggregated data while reducing the total number of encryption operations required, thereby decreasing processing time and clock cycles compared to encrypting each frame individually.
