Mesh Jamming Nodes for Decentralized Wide-Area Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio jamming systems rely on a central control node, leading to a single point of failure and limited area coverage, which is inefficient for wider area coverage and lacks redundancy.
Innovation Solution
A mesh jamming system with stateful control units in jamming nodes that communicate and distribute jamming jobs among each other, allowing for decentralized operation and increased redundancy without complete redundancy, using a finite state machine to manage states and communication frequencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single jamming node is used, then device complexity is reduced, but area coverage is limited
Solution Approach 1:
The jamming system is segmented into multiple independent jamming nodes distributed across the coverage area. Each node operates autonomously with local decision-making capability, eliminating the need for complex centralized control while collectively achieving wide area coverage through spatial segmentation.
2Reliability
If a central control node is used to coordinate multiple jamming nodes, then synchronization is improved, but reliability deteriorates due to single point of failure
Solution Approach 1:
The central control node is extracted and its coordination functions are distributed to individual jamming nodes. Each node maintains an internal state machine that autonomously handles synchronization, job execution, and coordination with neighboring nodes, eliminating the single point of failure while preserving synchronized operation.
Solution Approach 2:
The system transitions from static centralized control to dynamic decentralized control. Jamming nodes dynamically adjust their operation based on local conditions, receiving commands from upstream nodes and propagating jobs to downstream nodes, creating a flexible and resilient coordinated system without a fixed central authority.
3Area of stationary object
If jamming nodes are located within maximum distance of central control node, then control is simplified, but total area coverage is limited
Solution Approach 1:
The network topology transitions from a two-dimensional star topology (nodes around central controller) to a distributed mesh topology where nodes can communicate across multiple hops. This dimensional change in network architecture allows coverage to extend beyond the maximum radio distance of individual nodes while maintaining manageable complexity through localized peer-to-peer interactions.
