Solution Overview
Problem
Conventional networking protocols, such as BGP, struggle to maintain connectivity and security in mobile and airborne networks due to rapid node movement and directional changes, leading to communication outages and increased vulnerability to interference or compromise.
Innovation Solution
A network protocol with dynamic discovery mechanisms, proactive link monitoring, and a mobility index to anticipate node movement, ensuring seamless communication and secure link management in mobile environments, particularly in military applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard networking protocols like BGP are used with static peering mechanisms, then network stability is maintained in stationary environments, but connectivity breaks down in mobile environments with rapid node movement
Solution Approach 1:
The patent implements dynamic peer discovery and link establishment mechanisms that continuously adapt to node movement. Instead of static peering, the system uses periodic beacon signals and dynamic route advertisement to maintain connectivity as nodes enter and leave communication ranges, resolving the contradiction between reliability and mobile adaptability
Solution Approach 2:
The system performs preliminary route establishment and peer discovery before nodes actually need communication. By proactively advertising routes and establishing peering relationships in advance, the network maintains connectivity even when nodes move rapidly, preventing connection breaks rather than reacting to them
2Reliability
If transmitters with extended range are used to maintain connectivity in mobile networks, then communication coverage is improved, but network detectability and vulnerability to interference increase
Solution Approach 1:
The patent divides the network into multiple autonomous domains with local peer-to-peer communication. Instead of relying on a few high-power transmitters, the system segments communication into many low-power local links, maintaining coverage through distributed connectivity while reducing the detectability of individual transmitters
Solution Approach 2:
The system uses intermediary nodes to relay communications between distant nodes. Rather than requiring direct long-range transmission, intermediate nodes forward data packets, extending effective communication range through multiple short hops while keeping individual transmitter power and detectability low
3Adaptability or versatility
If nodes frequently enter and leave communication range in airborne networks, then network mobility is achieved, but communication outages and topology changes increase
Solution Approach 1:
The patent implements continuous route advertisement and link maintenance mechanisms that operate regardless of node movement. By continuously broadcasting presence information and route availability, the system maintains unbroken communication paths even as nodes frequently enter and leave ranges, ensuring continuity despite mobility
Solution Approach 2:
The system uses feedback from periodic beacon signals and link quality measurements to dynamically adjust routing decisions. Nodes continuously monitor link status and provide feedback about connectivity, allowing the network to adapt routes in real-time to maintain communication continuity as topology changes

AI summary
A device-implemented network with domains each having nodes, the nodes of each of the domains sharing network information with one another according to an intra-domain communication policy. An inter-domain protocol is configured to control communication between at least one of the nodes of one of the domains and at least one of the nodes of a different one of the domains. A broker is configured to be communicatively coupled to the nodes and configured to control communication according to the inter-domain protocol and to which all of the nodes of each of the plurality of domains are configured to send the network information.
