Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ad hoc radio communication networks face challenges with low throughput, long access times, non-permanent connectivity, and high bandwidth consumption due to frequent topology changes and the need for explicit information retransmission in scenarios like new participant entry or network splits/mergers.
Innovation Solution
The method involves using fictitious topology elements to convey application data, allowing the modulation of network topology without modifying existing protocols, thereby reducing bandwidth consumption and improving service availability by leveraging existing topology discovery mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit information retransmission is used for topology updates and application data, then reliability of information delivery is improved, but bandwidth consumption increases significantly
Solution Approach 1:
The patent merges topology update information and application data into a single message structure. When a node discovers topology changes, it bundles both the topology update and any pending application data together in one transmission, eliminating the need for separate retransmission protocols and reducing overall bandwidth consumption while maintaining delivery reliability.
Solution Approach 2:
The patent creates a universal message structure that can carry multiple types of information (topology updates, application data, acknowledgments) in a single transmission unit. This multi-functional message format allows nodes to convey different types of information efficiently without requiring dedicated protocols for each type, thereby reducing bandwidth usage while ensuring reliable delivery.
2Reliability
If dedicated channel headers and access protocols are used for application data exchanges, then data transmission reliability is improved, but bandwidth usage increases and exchange speed decreases
Solution Approach 1:
The patent combines application data with topology discovery messages, allowing application-layer information to be transmitted alongside network-layer topology updates. This merging eliminates the need for separate dedicated channel access protocols and reduces overhead, thereby improving data exchange speed while maintaining transmission reliability through the existing robust topology protocol.
Solution Approach 2:
The patent employs a universal message structure that serves multiple purposes: it functions as both a topology update carrier and an application data transport mechanism. This multi-functional approach allows the system to leverage the existing reliable topology protocol for data transmission without requiring additional dedicated protocols, thus improving productivity while preserving reliability.
3Measurement precision
If topology discovery protocols are run frequently to maintain up-to-date network topology knowledge, then network topology accuracy is improved, but bandwidth consumption and resource access time increase
Solution Approach 1:
The patent implements preliminary bundling of application data with topology update messages. Before topology changes occur, nodes prepare and bundle application data with anticipated topology update messages. This preliminary action ensures that when topology discoveries are made, both the topology information and application data are transmitted together in a single operation, maintaining topology accuracy while minimizing additional bandwidth consumption.
4Ease of operation
If application data is transmitted separately from topology updates, then data transmission control is improved, but overall transmission efficiency decreases due to increased message overhead
Solution Approach 1:
The patent merges application data transmission with topology update processes by bundling both types of information into single messages. This merging maintains operational control through the structured message format while dramatically improving transmission efficiency by eliminating redundant message overhead and reducing the total number of transmissions required.
