Mesh Network Topology Reconstruction for Bottleneck Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current relay discovery and selection mechanisms in wireless mesh networks fail to address network bottlenecks effectively, as they do not consider overall network performance and are limited to link-level optimizations, leading to reduced throughput.
Innovation Solution
A communication system and method that involves centralized node coordination to probe and reconstruct network topology by identifying and integrating idle/inactive participant nodes, utilizing multi-hop links and sidelinks to improve network structure and throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay discovery and selection mechanism is used for resolving bottleneck area, then link-level service requirement and performance optimization are considered, but overall network performance is not improved
Solution Approach 1:
The patent segments the network optimization problem into multiple levels: link-level optimization (existing relay discovery) and network-level optimization (new multi-hop relay selection). By dividing the system into manageable segments with different optimization goals, it achieves both link-level reliability and overall network performance improvement
Solution Approach 2:
The patent transitions from single-hop relay selection to multi-hop relay selection, adding the dimension of hop count to the relay selection process. This dimensional change allows the system to consider overall network topology and performance rather than just individual link quality
2Reliability
If conventional relay selection is used, then link-level optimization is achieved, but network throughput cannot be effectively improved
Solution Approach 1:
The patent performs preliminary actions by selecting multiple candidate relays in advance (multi-hop relays) before data transmission begins. This preliminary selection of relay chains allows the system to optimize end-to-end paths proactively, improving overall network throughput rather than reacting to link-level issues
3Productivity
If multi-hop relay selection is implemented, then overall network performance is improved, but system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where relays report their status and channel conditions back to the source node. This feedback enables the source node to make informed decisions about multi-hop relay selection, managing the increased system complexity through structured information exchange and decision-making protocols

AI summary
A communication system and method are provided. For a wireless mesh (Mesh) network architecture, uplink and downlink multi-hop links and multi-hop sidelinks (sidelink) between users are considered. When a bottleneck area appears in a network, an intra-network node (for example, a terminal device) probes, under coordination of a centralized node (for example, a base station), participant nodes in an idle or inactive (idle/inactive) state in networks that are managed by different centralized nodes, obtains network topology information of a multi-hop participant node, selects, based on a requirement for improvement in overall network performance, an appropriate participant node to join the network, reestablishes a wireless link, and performs network structure reconstruction, to break through a network bottleneck and greatly improve a network throughput.
