Digital Data Encoding for Ad Hoc Dissemination Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless ad-hoc networks, tracking data dissemination is challenging due to high resource consumption and vulnerability of verification data, making it difficult to identify which nodes assist in data dissemination.
Innovation Solution
A method involving encoding digital data with sign data using a linear combination operation to create encoded data that maintains the original data size, allowing for efficient tracking of data dissemination devices by decoding the error position within the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current tracking methods are used to track data dissemination in wireless ad-hoc networks, then data dissemination tracking is achieved, but network resources are consumed heavily
Solution Approach 1:
The patent combines data encoding and tracking information embedding into a single linear combination operation. Sign data representing dissemination device information is encoded into the digital data through linear combination, merging the tracking function with the data transmission process itself, thereby eliminating separate tracking mechanisms and reducing network resource consumption.
Solution Approach 2:
The encoded digital data serves multiple functions simultaneously: it carries the original information content and embeds tracking information about dissemination devices. The linear combination encoding process creates a universal data structure that enables both data transmission and tracking verification without requiring separate dedicated tracking channels or protocols.
2Reliability
If verification data is used to track data dissemination, then data dissemination tracking is achieved, but verification data is easily destroyed
Solution Approach 1:
Instead of using separate verification data structures that are vulnerable to destruction, the patent merges tracking information directly into the data encoding process. The sign data is integrated into the digital data through linear combination, creating a unified structure where tracking information and original data are inseparable, thus protecting tracking information from being easily destroyed or lost.
Solution Approach 2:
The patent transforms the tracking mechanism from using separate verification data to embedding sign data within the data itself through parameter changes in the encoding process. By changing how tracking information is represented and integrated into the data structure, the system achieves more robust tracking that resists data loss and destruction.
3Quantity of substance
If sign data is encoded into digital data through linear combination operation, then data size remains unchanged, but decoding complexity increases
Solution Approach 1:
The patent segments the decoding process into distinct steps: receiving the encoded digital data, decoding to obtain the codeword, identifying error positions, and extracting sign data. This segmentation of the decoding process into manageable stages reduces overall complexity by making each step independent and well-defined, despite the inherent complexity of linear code decoding.
