Ad-hoc Mobile Node Network Satellite Gap Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ad-hoc communication networks face gaps in routing options, as not all mobile nodes can establish seamless communication paths due to limited radio range and availability of mobile nodes, leading to potential message loss or delayed delivery.
Innovation Solution
The method involves forming an ad-hoc communication network using mobile nodes and supplementing communication gaps with alternative signals, such as satellite communication, to ensure message delivery between mobile nodes and stationary stations, leveraging complementary strengths of air-to-air and satellite communication systems for cost-effective and wide coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If ad-hoc communication networks use mobile node-to-mobile node relay systems, then cost-effective coverage is achieved by eliminating fixed stations, but routing reliability deteriorates when mobile nodes are insufficient or improperly positioned
Solution Approach 1:
The patent introduces satellite communication as an intermediary system to bridge gaps in ad-hoc mobile networks. When mobile nodes cannot establish direct routing paths, the satellite acts as a mediator to relay messages between mobile nodes and fixed stations, ensuring delivery without requiring dense mobile node deployment.
Solution Approach 2:
The communication system is designed to perform multiple functions: it operates as a mobile node-to-mobile node relay system when conditions permit, and automatically switches to satellite communication when routing gaps are detected. This multi-functionality allows the system to maintain reliability across varying deployment conditions while remaining cost-effective.
2Device complexity
If ad-hoc networks rely solely on mobile nodes for message relaying, then system complexity is reduced, but message delivery reliability worsens due to insufficient mobile node availability
Solution Approach 1:
The system dynamically adapts its communication path based on real-time conditions. Mobile nodes continuously assess whether sufficient relay nodes are available within radio range, and the system automatically transitions between mobile-only routing and satellite-assisted routing modes, maintaining optimal performance without requiring complex pre-planning.
Solution Approach 2:
The ad-hoc network performs self-diagnosis to detect routing gaps by evaluating mobile node positions and signal strength. When gaps are detected, the system autonomously switches to satellite communication without requiring external control or manual intervention, maintaining reliability while keeping the system relatively simple.
3Ease of manufacture
If mobile nodes are sparsely distributed to reduce costs, then cost-effectiveness improves, but communication coverage deteriorates creating routing gaps
Solution Approach 1:
The patent extends the communication system from a two-dimensional ground-based mobile node network into the third dimension by incorporating satellite communication. This dimensional transition allows sparse mobile node deployment on the ground while maintaining comprehensive coverage through the satellite's orbital position, eliminating the need for dense mobile node distribution.
