Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In areas with limited broadband Internet infrastructure, existing technologies face challenges in efficiently delivering high-bandwidth digital content to users, particularly in developing nations where connectivity is restricted, leading to suboptimal content distribution and access.
Innovation Solution
A wireless mesh network (WMN) architecture is implemented, utilizing multi-radio, multi-channel (MRMC) mesh network devices with antenna switching circuitry and a mesh network control service to establish a self-contained network that distributes content through peer-to-peer connections, caching content locally and using cellular connections for control data, thereby bypassing the need for direct Internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional broadband Internet infrastructure is used for content distribution, then high-bandwidth content delivery is achieved, but infrastructure availability and cost are limited in developing nations
Solution Approach 1:
The patent segments the content distribution system into multiple independent mesh network nodes that operate autonomously. Each node can store and distribute content locally, eliminating dependency on centralized broadband infrastructure. This segmentation enables content delivery in areas without Internet connectivity while maintaining high distribution efficiency through distributed peer-to-peer transfers.
Solution Approach 2:
The patent introduces mesh network nodes as intermediary devices between content sources and end users. These nodes relay content through wireless mesh connections, bypassing the need for direct broadband Internet access. The intermediary nodes enable content distribution in infrastructure-limited areas by creating alternative transmission paths.
2Reliability
If wireless mesh network is implemented for content distribution in areas with limited connectivity, then network availability and accessibility are improved, but network complexity and device requirements increase
Solution Approach 1:
The patent designs mesh network nodes with multi-functionality to reduce overall system complexity. Each node can simultaneously perform routing, content storage, content distribution, and client device servicing functions. This universality eliminates the need for separate specialized devices, simplifying deployment while maintaining reliable network availability.
Solution Approach 2:
The patent combines multiple network functions into single mesh network devices. The nodes integrate content delivery network (CDN) capabilities, wireless access point functionality, and routing operations into unified devices. This merging reduces the number of components needed in the network while improving reliability through functional integration.
3Productivity
If multiple radios and channels are used in mesh network devices for concurrent connections, then content distribution speed and efficiency are improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent implements dynamic radio and channel allocation in mesh network nodes. The system actively monitors network conditions, traffic patterns, and energy levels to adjust radio usage and channel selection in real-time. This dynamics enables high-speed content distribution when conditions permit while conserving energy during low-traffic periods or when battery levels are low.
Solution Approach 2:
The patent changes operational parameters such as transmission power, channel frequency, and radio activation states based on network conditions. By dynamically adjusting these parameters, the system optimizes content distribution speed when multiple radios are active while reducing energy consumption when fewer resources are needed, resolving the contradiction between productivity and energy use.
4Speed
If mesh network nodes cache content locally for distribution, then content access speed and reliability are improved, but storage requirements and device complexity increase
Solution Approach 1:
The patent implements local quality caching where each mesh network node stores content based on its specific characteristics, location, and predicted local demand. Rather than uniform caching across all nodes, the system tailors storage content to local needs, improving content access speed for relevant users while optimizing storage utilization across the network.
Solution Approach 2:
The patent employs preliminary content caching by predicting which content will be needed in specific network areas and pre-positioning it at appropriate mesh nodes before demand occurs. This preliminary action reduces latency and improves access speed while avoiding unnecessary storage of content that would not be used, optimizing the balance between speed and storage capacity.
