Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional network approaches struggle to provide ultra-reliable network connectivity in densely automated environments, leading to congestion, resource overconsumption, and spotty coverage due to dynamic conditions and interference, which undermines network performance and reliability.
Innovation Solution
An opportunistic relay mechanism among mobile communication devices is introduced, where mobile devices with adequate wireless communication characteristics are selected to relay communications for devices with inadequate connectivity, using encryption keys distributed at association time to ensure secure and efficient network redundancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network approaches are used to support dense automated deployments, then network coverage is provided, but network congestion and resource overconsumption occur, compromising reliability and performance
Solution Approach 1:
The patent introduces mobile devices as intermediary relay nodes to forward communications between other mobile devices and the network infrastructure. These opportunistic relays extend network coverage and improve reliability without requiring additional dedicated network resources, as they utilize existing mobile device hardware and wireless connections.
Solution Approach 2:
The system leverages existing mobile devices that users already carry and operate. These devices self-organize to provide relay services when needed, without requiring users to actively participate or additional network infrastructure. The mobile devices use their own communication resources to assist the network, converting potential resource consumption into useful network support.
2Reliability
If mobile devices are used as opportunistic relays to extend coverage, then network reliability is improved, but device complexity and coordination overhead increase
Solution Approach 1:
The system continuously monitors wireless communication characteristics such as signal strength, interference levels, and device locations. This feedback enables the network to dynamically identify suitable relay candidates and optimize relay selection based on current conditions, ensuring reliable connectivity while adapting to changing environmental factors without requiring complex manual configuration.
Solution Approach 2:
The patent changes the operational parameters of mobile devices dynamically based on network conditions. Devices transition between normal operation and relay mode based on real-time assessment of wireless characteristics. This parameter-based approach simplifies coordination by using measurable physical quantities rather than complex device-state management.
3Area of stationary object
If relay devices are deployed to address spotty coverage areas, then network coverage is improved, but spectrum strain and resource consumption increase
Solution Approach 1:
The relay functionality is dynamic rather than static. Mobile devices become relays only when and where needed based on real-time network conditions and coverage requirements. This dynamic approach ensures coverage in spotty areas without permanently dedicating devices to relay functions, thereby reducing overall spectrum strain and energy consumption compared to fixed relay deployments.
4Reliability
If encryption is implemented for secure relay communication, then communication security is improved, but processing overhead and latency increase
Solution Approach 1:
Encryption keys are distributed to mobile devices in advance during the association phase with the network. When a device becomes a relay, the encryption is already configured and ready to use, eliminating the need for real-time key exchange or setup. This preliminary action ensures secure communication without adding latency during the actual relay operation.
