Ad-hoc Network Data Transmission Quality Factor Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ad-hoc networks face challenges in efficiently routing large volumes of image data due to equipment saturation and unpredictable data routing, particularly in high-density and low-density environments, where data profusion and limited relay equipment availability hinder effective data transmission.
Innovation Solution
A method for data transmission in ad-hoc networks that updates a quality factor for each mobile equipment based on its data transmission history, prioritizing equipment with a good history for routing data to collection terminals, and limits the number of hops and equipment involved to prevent data profusion, without requiring knowledge of user movement habits or control signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data are transmitted through multiple hops in high-density equipment zones, then data can reach collection terminals more effectively, but data profusion occurs causing equipment saturation
Solution Approach 1:
The patent implements a feedback mechanism where each mobile equipment updates its quality factor based on the number of data copies received from previous hops. Equipment with higher quality factors (fewer copies) is prioritized for data transmission, creating a self-regulating system that prevents data profusion while ensuring reliable delivery through multiple hops when necessary.
Solution Approach 2:
The patent introduces a dynamic quality factor parameter that changes based on transmission history and data copy counts. This parameter allows the system to adaptively adjust routing decisions in real-time, favoring paths with fewer data copies and preventing saturation in high-density zones while maintaining effectiveness in low-density areas.
2Reliability
If data are routed through physical movement of users in low-density zones, then data can reach collection terminals, but routing becomes unpredictable
Solution Approach 1:
The patent enables the ad-hoc network to route data autonomously based on quality factors without requiring knowledge of user movement habits or external control signals. Each equipment independently evaluates its own quality factor and makes routing decisions, creating a self-managing system that works effectively in low-density zones where user movement is unpredictable but still achieves reliable data delivery.
3Reliability
If quality factor updates are performed for each transmission, then data routing is optimized, but processing time increases
Solution Approach 1:
The patent applies partial updates to quality factors rather than complete recalculations. Equipment updates its quality factor based on the specific transmission event (adding or subtracting a value) rather than performing full optimization algorithms, achieving sufficient routing optimization with minimal processing time overhead.

AI summary
The invention relates to a method of data transmission by an ad-hoc network of mobile communication equipment (16a, 16b, 16c, 16d), from at least one source equipment (12) to at least one collection terminal (14), by means of mobile relay equipment (16c), in which for each communication equipment, at least one quality factor is updated (Q0, Q1, Q2 Q3, Q4, Q5). According to the invention, the quality factor of each relay equipment depends on a history of data transmission, and data transmission from mobile equipment to mobile relay equipment is conditional on the quality factor of the relay equipment capable of receiving the data.
