Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks often inefficiently utilize spectral resources due to mismatched allocation with network load, and existing methods lack efficient mechanisms for acquiring information about neighboring nodes without direct communication, which complicates resource sharing and interference management.
Innovation Solution
A method where a wireless node sends a registration request message with location and communication-related information to a location database, receiving a neighbor list message that includes spectral allocation details for registered neighboring nodes, enabling efficient resource sharing and allocation based on proximity and communication parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If spectral resources are allocated to each wireless network to decrease interference, then interference is reduced, but spectral resources cannot be efficiently utilized when network load varies
Solution Approach 1:
The patent implements dynamic spectral resource allocation where the location database continuously updates spectral allocation information based on real-time network load conditions. Wireless nodes can dynamically borrow spectral resources from neighboring networks when their allocated resources are insufficient, allowing the system to adapt to varying load demands while maintaining interference reduction through coordinated resource management.
Solution Approach 2:
The location database serves as an intermediary that coordinates spectral resource sharing between different wireless networks. It stores and manages spectral allocation information for multiple networks and enables wireless nodes to query and borrow resources from neighboring networks without direct peer-to-peer negotiation, thus improving resource efficiency while maintaining controlled interference management.
2Adaptability or versatility
If wireless nodes directly communicate with neighboring nodes to share resources, then resource sharing is enabled, but the complexity of acquiring information about neighboring nodes increases
Solution Approach 1:
The location database acts as a centralized intermediary that stores spectral allocation information for all registered wireless networks. Instead of requiring wireless nodes to directly communicate and negotiate with multiple neighboring nodes, nodes simply query the location database which provides the necessary information about available spectral resources, thereby simplifying the information acquisition process while enabling comprehensive resource sharing.
Solution Approach 2:
The location database automatically maintains and updates spectral allocation information as networks are registered or modify their resource allocations. Wireless nodes can independently query the database for resource information without needing to initiate complex communication protocols with neighboring nodes, enabling self-service resource information acquisition that reduces system complexity.
3Device complexity
If spectral resources are allocated based on fixed network configuration, then interference management is simplified, but resources cannot be efficiently utilized when network load changes
Solution Approach 1:
The system transitions from fixed spectral allocation to dynamic allocation where the location database continuously tracks network load conditions and updates spectral resource availability information. Wireless nodes can borrow additional spectral resources from neighboring networks when their allocated resources are insufficient, allowing the system to dynamically adapt to changing load conditions while maintaining relatively simple interference management through the centralized database approach.
