Solution Overview

Problem

Current data management systems in distributed geospatial communications rely on central databases, which can be inaccessible, leading to inefficiencies in data exchange between mobile nodes, especially in scenarios like monitoring unmanned aerial vehicles (UAVs) where real-time data is crucial.

Innovation Solution

A method for mobile nodes to establish direct wireless network connections and exchange pertinent data within predefined geospatial areas without relying on centralized databases, allowing for spontaneous formation of ad-hoc data repositories and enabling data 'handoff' between nodes as they enter or leave areas, ensuring data persistence and availability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If centralized databases are used for data management in distributed geospatial communications, then data storage capacity is improved, but system reliability deteriorates when central databases are inaccessible

Engineering Contradiction:

Improvedata storage capacityVSAvoidsystem availability

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The patent segments the centralized database into distributed data stores located at multiple mobile nodes throughout the geospatial area. Each node maintains local data storage capabilities, eliminating the single point of failure represented by a central database. This segmentation allows the system to remain operational even when individual nodes or communication paths fail, as other nodes can continue to provide data storage and retrieval services.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces mobile nodes as intermediary entities that mediate between data requests and data storage. Instead of direct client-server communication with a central database, mobile nodes act as distributed intermediaries that store, manage, and retrieve data locally. This intermediary layer provides redundancy and fault tolerance, as multiple intermediaries can serve the same data needs if one becomes unavailable.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If mobile nodes establish direct wireless connections for data exchange, then system complexity is reduced, but data availability deteriorates when nodes leave the predefined geospatial area

Engineering Contradiction:

Improvenetwork architecture complexityVSAvoiddata persistence

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements preliminary action through data handoff mechanisms. When a mobile node is about to leave the predefined geospatial area, it proactively transfers its stored data to another node within the area before departing. This preliminary data transfer ensures that data persists within the geospatial boundary even as nodes dynamically join and leave, maintaining data availability without requiring complex infrastructure to track and manage node movements.

Inventive Principle:

Principle #10Preliminary action

3Loss of information

If data is transmitted to central repositories, then data centralization is improved, but bandwidth usage increases due to redundant data transmission

Engineering Contradiction:

Improvedata centralizationVSAvoidbandwidth consumption

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The patent applies local quality by allowing mobile nodes within the same geospatial area to share data directly through peer-to-peer wireless connections, rather than routing all data through a central repository. This localized data exchange optimizes bandwidth usage by eliminating redundant transmissions to and from the center. Each node maintains data locally relevant to its geospatial context, reducing the need for centralized data duplication and transmission.

Inventive Principle:

Principle #3Local quality

4Stability of the object's composition

If centralized database management is used, then data synchronization is improved, but processing burden on central servers increases

Engineering Contradiction:

Improvedata synchronizationVSAvoidcentral server processing capacity

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent implements self-service by enabling mobile nodes to autonomously manage their own data storage and synchronization without requiring centralized server processing. Each node independently maintains its local data store and handles data exchange with other nodes through direct wireless communications. This distributes the processing burden across all participating nodes rather than concentrating it on central servers, improving overall system productivity while maintaining data synchronization through peer-to-peer protocols.

Inventive Principle:

Principle #25Self-service

AI summary

A method on a first mobile node for facilitating exchange of pertinent data between mobile nodes over a wireless communications network can be provided. The method can include establishing, by the first mobile node, a wireless network connection with at least one other mobile node inside a predefined geospatial area, wherein the wireless network connection is established over the wireless communications network. The method can further include determining that a future position of the first mobile node is outside the predefined geospatial area and transmitting pertinent data residing on the first mobile node over the wireless communications network exclusively to the at least one other mobile node inside the predefined geospatial area, wherein the pertinent data is associated with the predefined geospatial area.
