Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile ad-hoc networks (MANETs) face inefficiencies due to limited transmission range and topological constraints, which restrict their coverage to a few kilometers and lead to bottlenecks and traffic congestion, especially in challenging terrains.
Innovation Solution
The integration of dual-type backbone nodes with satellite communication capabilities into MANETs, allowing nodes to dynamically select between ordinary and backbone roles and utilize multiple communication links, including satellite and mobile wireless links, for enhanced routing and connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If MANET nodes use only mobile wireless communication with limited transmission range, then device complexity is reduced, but network coverage area is restricted to a few kilometers
Solution Approach 1:
The patent applies multi-functionality by enabling MANET nodes to operate with multiple communication interfaces (mobile wireless and satellite) within the same network. Nodes can dynamically select between ordinary mode (mobile wireless only) and backbone mode (both mobile wireless and satellite), allowing the network to expand coverage area while managing device complexity through role-based interface activation.
2Quantity of substance
If MANET nodes are added to extend network coverage, then network capacity increases, but traffic congestion and bottlenecks worsen
Solution Approach 1:
The patent applies segmentation by dividing the MANET into two distinct segments: ordinary nodes that communicate via mobile wireless only, and backbone nodes that utilize both mobile wireless and satellite interfaces. This segmentation creates a hierarchical structure where backbone nodes handle long-range communications and routing, thereby extending network capacity without proportionally increasing traffic congestion in the mobile wireless segment.
3Reliability
If satellite communication interfaces are added to backbone nodes, then network resilience against topographical obstacles improves, but device complexity increases
Solution Approach 1:
The patent applies dynamics by implementing dynamic role assignment where nodes can switch between ordinary and backbone modes based on network conditions, terrain requirements, and communication needs. Backbone nodes with satellite interfaces are dynamically selected and configured only when needed for long-range communications or when topographical obstacles block mobile wireless paths, thereby improving reliability while minimizing the number of nodes that require complex dual-interface configuration.
4Productivity
If dual-type backbone nodes with satellite capabilities are deployed, then network efficiency in challenging terrains improves, but manufacturing and deployment cost increases
Solution Approach 1:
The patent applies local quality by deploying satellite communication capabilities only at specific locations within the network where backbone nodes are positioned, rather than equipping all nodes with satellite interfaces. This localized deployment allows efficient data transmission in challenging terrains through strategically placed satellite-capable backbone nodes, while reducing overall manufacturing and deployment costs compared to universal satellite equipment installation.

AI summary
A mobile ad-hoc communications network with multi-interface dynamic routing includes multiple mobile nodes with mobile wireless communication and multiple mobile nodes with mobile wireless communication and satellite communication. At least some of the mobile nodes with mobile wireless communication are dynamically-switched between operating as an ordinary node or as a backbone node. At least some of the mobile nodes with mobile wireless communication and satellite communication are dynamically-switched between operating as an ordinary node or as a backbone node. All of the mobile nodes communicate over a dynamically-formed ordinary communication link. Mobile nodes operating as backbone nodes additionally communicate over a dynamically-formed backbone link. Data is routed in the network by an ad-hoc multi-interface dynamic routing which routes data between the mobile nodes by mobile wireless communication and by satellite communication in accordance with respective communication capabilities of the mobile nodes, so as to incorporate satellite communications into the network.
