Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ad hoc wireless networks face inefficiencies in establishing and maintaining reliable communication routes due to dynamic node positioning and resource utilization changes, leading to potential communication disruptions and suboptimal bandwidth usage.
Innovation Solution
A method involving a wireless infrastructure access network with a wireless-enabled infrastructure gateway node (WIG) and wireless-enabled network nodes (WNNs) that periodically transmit beacon and status messages to establish and adjust communication paths based on current bandwidth utilization and quality of service (QoS) requirements, using a bi-directional packet pathway to optimize resource utilization and route selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If nodes maintain separate lists of all nodes and communication paths in ad hoc wireless networks, then network efficiency and transmit time are improved, but device complexity increases significantly
Solution Approach 1:
The patent introduces a centralized network manager as an intermediary that maintains the comprehensive routing tables and node lists. Individual nodes only maintain simple neighbor information, while the network manager handles the complex path management. This mediator approach resolves the contradiction by centralizing complexity while maintaining efficiency.
Solution Approach 2:
The patent segments the network management function into two parts: simple node-level operations for local communication and centralized network-level management for global routing. This segmentation allows nodes to remain simple while the system as a whole maintains high efficiency through centralized coordination.
2Stability of the object's composition
If static networks establish and maintain paths among nodes, then path stability is improved, but adaptability to dynamic node positioning and network changes deteriorates
Solution Approach 1:
The patent implements dynamic routing tables that are continuously updated based on current network conditions. The network manager actively monitors node positions and connectivity changes, then dynamically adjusts routing paths. This dynamic approach allows the network to maintain stability through consistent routing logic while adapting to changing physical conditions.
Solution Approach 2:
The patent employs feedback mechanisms where nodes periodically report their status and position to the network manager. This feedback loop enables the system to detect network changes and update routing paths accordingly, maintaining both stability through structured updates and adaptability through continuous monitoring.
3Ease of operation
If nodes transmit and receive communication messages in wireless networks, then communication capability is improved, but signal degradation and interference from electromagnetic waves increase
Solution Approach 1:
The patent uses intermediate relay nodes as mediators to transmit messages between nodes that are too far apart for direct communication. By routing messages through multiple hops via relay nodes, the system overcomes signal degradation and interference limitations, allowing communication capability to extend beyond direct line-of-sight constraints.
