Adaptive Data Splitting and XOR Transmission for Wireless Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication techniques struggle to maintain an appropriate amount of data transmission per unit time, especially in varying communication states.
Innovation Solution
A communication device calculates a split number based on transmission parameters, splits data into multiple pieces, and transmits these pieces as individual units or exclusive OR combinations, adjusting the number of splits based on communication state to optimize data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted as whole packets, then transmission speed is maintained, but packet loss increases in bad wireless communication states
Solution Approach 1:
The patent divides transmission data into multiple smaller packets (split data) based on transmission parameters such as packet loss rate and communication state. This segmentation allows the receiver to reconstruct the original data even if some packets are lost, thereby improving reliability without significantly reducing the overall data transmission amount.
2Reliability
If packet encoding and data splitting are performed, then communication reliability improves, but transmission time increases
Solution Approach 1:
The patent dynamically adjusts the number of split packets and encoding parameters based on real-time transmission parameters including packet loss rate, communication state, and data size. When communication conditions are good, the system uses fewer splits to minimize time loss; when conditions deteriorate, it increases splitting to maintain reliability.
Solution Approach 2:
The system changes encoding parameters such as the number of split packets, error correction codes, and transmission frequency based on measured transmission parameters. This adaptive parameter adjustment optimizes the balance between reliability improvement and time loss reduction under varying communication conditions.
3Reliability
If transmission data is split into multiple pieces, then packet loss resistance improves, but device complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the communication device automatically measures transmission parameters (packet loss rate, communication state) and autonomously determines optimal splitting parameters without external intervention. This automation reduces the operational complexity while maintaining the benefits of data splitting for packet loss resistance.

AI summary
A communication device calculates a setting value of a split number of transmission data, based on a transmission parameter between the communication device and a transmission destination communication device to which the transmission data is to be transmitted. The communication device splits the transmission data based on the setting value of the split number to obtain a plurality of pieces of split data. The communication device generates a plurality of transmission units and transmits the plurality of transmission units to the transmission destination communication device. The plurality of transmission units includes: a transmission unit that includes one of the plurality of transmission units; and a transmission unit composed of an exclusive OR of a plurality of pieces of split data that are selected randomly from the plurality of pieces of split data.
