Per-Link Resource Discovery in Multi-Hop Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless cellular communication systems only allow devices to announce and allocate resources on a per device basis, lacking the ability to advertise capabilities and resources on a per link basis, which limits efficient resource utilization and routing in multi-hop systems.
Innovation Solution
A method and system that enable devices to send and receive resource discovery queries on a per link basis, allowing for dynamic allocation and reallocation of resources such as memory, processing power, and bandwidth across multiple links, and to establish wireless links based on available resource information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If devices announce resources on a per device basis, then device capability information is provided, but resource allocation efficiency deteriorates due to inability to advertise capabilities on a per link basis
Solution Approach 1:
The patent segments the device's resource capabilities into per-link allocations. Instead of announcing a single aggregate category for the entire device, the system divides resources into link-specific categories, allowing each wireless link to have its own resource allocation announcement. This enables more precise resource management and efficient allocation across multiple simultaneous links.
Solution Approach 2:
The patent introduces a new dimension to resource announcement by adding the link dimension to the traditional device-level category system. Resources are now announced not just at the device level but also at the link level, creating a hierarchical structure where device categories are decomposed into link-specific categories. This dimensional expansion enables fine-grained resource control.
2Adaptability or versatility
If a device establishes a single link with access node, then simple category announcement is maintained, but multi-hop routing capability deteriorates
Solution Approach 1:
The patent segments the communication paradigm from single-link to multi-link by allowing devices to establish and manage multiple simultaneous wireless links. Each link is treated as an independent communication path with its own resource allocation, enabling devices to participate in multi-hop networks where they can simultaneously communicate with multiple neighbors.
Solution Approach 2:
The patent makes devices universal by enabling them to perform multiple functions simultaneously - acting as both endpoint and relay, maintaining multiple links at once, and participating in various roles within the network. The per-link resource announcement mechanism supports this multi-functionality by allowing flexible resource distribution across different links.
3Productivity
If per link resource information is not provided, then simpler resource management is maintained, but communication efficiency deteriorates due to inability to dynamically allocate resources across multiple links
Solution Approach 1:
The patent segments resource information into per-link components, where each link has its own category announcement indicating the resources allocated to that specific link. This segmentation provides the granularity needed for efficient resource management while maintaining clear, structured information exchange between devices.
