Adaptive Data Format Selection for Wireless Network Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks, particularly mobile ad hoc networks, face challenges in efficiently routing data due to congestion, rapid changes in bandwidth, and link quality, leading to incomplete or corrupted data transmission, especially in emergency situations where timely and reliable data transfer is critical.
Innovation Solution
A method that involves a software application module requesting the status of a network route before data transmission, allowing it to choose a data format based on the current network conditions, thereby adapting to available resources and ensuring efficient use of bandwidth by transmitting data in a format that is suitable for the network's capabilities at the time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data is transmitted in high-quality format across a MANET, then information completeness is improved, but network reliability deteriorates due to congestion and link quality changes
Solution Approach 1:
The patent implements dynamic format selection where the software application module adapts the data format based on real-time network status. The system transitions from static high-quality format transmission to dynamic format adjustment, selecting between high-quality and reduced-quality formats according to current network conditions, thereby resolving the contradiction between information completeness and transmission reliability
Solution Approach 2:
The patent changes the data format parameter (quality level) based on network status parameters. When network conditions deteriorate, the system modifies the data representation parameter from high-quality to reduced-quality format, allowing transmission to proceed reliably while accepting some information loss, thus resolving the contradiction
2Reliability
If data retransmission is performed after failed transmission, then information delivery is improved, but network congestion worsens
Solution Approach 1:
The patent checks network status before initiating data transmission as a preliminary action. By assessing network conditions in advance and selecting an appropriate data format beforehand, the system prevents transmission failures that would require retransmission, thereby improving delivery success while avoiding the congestion caused by retransmission cycles
Solution Approach 2:
The patent converts the potential harm of network congestion into a benefit by using network status information to proactively select reduced-quality data formats when congestion is detected. This transforms the harmful condition (congestion) into a useful signal for format selection, preventing failed transmissions and the need for congestion-causing retransmissions
3Reliability
If network status checking is performed before each transmission, then transmission reliability is improved, but time consumption increases
Solution Approach 1:
The patent implements a self-service mechanism where the software application module autonomously checks network status and selects appropriate data formats without external intervention. This automation resolves the contradiction by making the reliability-improving status check an integrated, efficient part of the transmission process rather than a separate overhead activity
Data Source
AI summary
Information is transmitted across a wireless data network, comprising a wireless link (100) from a software application module on a computer hardware device (112) to a computer hardware device (110) associated with a destination node in the network. The application requests (114) the status of the route across the network, such information being optionally provided by a decision engine (104) which has access to network status parameters, such as bandwidth, latency and link quality. The application receives (118) the status information and then, and preferably only then, transmits (120) the data in a format chosen from a plurality of different formats (of differing richness of information represented by the date in each such format) in dependence on the indication of the status so received.
