Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ad hoc mobile networks face challenges in establishing scalable IP networks due to limitations in resource management, latency, throughput, and adaptability, especially in constrained environments like sea-based deployments, where radio range limitations and dynamic node configurations complicate network reliability and interoperability.
Innovation Solution
A method for dynamically discovering and configuring ad hoc IP networks among mobile nodes using a priority-based token mechanism, where a maximum time window is determined by a highest priority node, and nodes can integrate or exclude each other based on priority indicators, facilitating relay modes and optimizing data exchange through speech and invitation tokens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If TDMA protocol is used for strict resource management, then interference between transmitters is limited, but data exchange latency and throughput are significantly limited
Solution Approach 1:
The patent implements dynamic TDMA slot allocation where time slots are not fixed but can be dynamically assigned and reassigned based on real-time network conditions, node priorities, and traffic demands. This allows the system to adapt slot assignments dynamically, reducing latency for high-priority communications while maintaining interference management benefits of TDMA.
Solution Approach 2:
The system changes multiple parameters including time slot durations, slot allocation patterns, and transmission power levels based on network conditions. By adjusting these parameters dynamically, the system optimizes both interference management and data exchange efficiency, resolving the contradiction between structured access and performance.
2Ease of operation
If TDMA protocol is used for strict resource management, then channel access is organized, but available bandwidth resources are under-utilized
Solution Approach 1:
The patent implements dynamic TDMA slot allocation where time slots are not fixed but can be dynamically assigned and reassigned based on real-time network conditions, node priorities, and traffic demands. This allows the system to adapt slot assignments dynamically, reducing latency for high-priority communications while maintaining interference management benefits of TDMA.
Solution Approach 2:
The system ensures continuous utilization of bandwidth by dynamically adjusting slot allocations to match actual traffic demands. When nodes have data to transmit, they are granted appropriate slot access; when idle, slots are reassigned or consolidated. This eliminates the waste of reserved but unused time slots while maintaining organized channel access.
3Adaptability or versatility
If ad hoc network allows dynamic reconfiguration and flexibility, then network adaptability is improved, but deployment complexity and node coordination difficulty increase
Solution Approach 1:
The patent implements self-organizing mechanisms where nodes autonomously discover each other, negotiate roles, and configure network parameters without centralized control. Nodes automatically perform functions such as priority determination, slot allocation, and route establishment based on local information and predefined protocols, enabling dynamic reconfiguration while keeping individual node complexity manageable.
Solution Approach 2:
The system segments network management functions into modular, distributed components that can be independently implemented and executed by different nodes. This segmentation allows complex coordination tasks to be broken down into simpler local decisions, reducing overall deployment complexity while maintaining network-wide adaptability.

AI summary
The invention relates to a method for discovering a network among a plurality of mobile nodes, which includes: a first mobile node (NOD1) periodically transmitting a first signal including an invitation token comprising data relating to an identity of the node (IÔNOD-I) which transmits said token; a second mobile node (NOD2) detecting the first signal; transmitting a second signal including at least one acknowledgement of the invitation token; creating a radio bubble, said communications between the nodes of the radio bubble being coordinated by transmitting a speech token between said nodes; and creating an IP sub-network between the nodes of the radio bubble, each node including an IP address.
