Current communication networks are inadequate in supporting complex environments with both moving and static nodes, such as the Internet of moving things and autonomous vehicle networks, as they fail to provide robust, scalable, and efficient connectivity and management of mobility.

Innovation Solution

A communication network architecture that dynamically configures a complex array of both static and moving nodes, utilizing mobile and fixed access points to provide always-on, secure, and energy-efficient connectivity, with adaptive management of mobility and handovers between access points, and the use of multi-network on-board units (OBUs) to create a vehicular mesh network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current communication networks are used to support moving and static nodes, then basic connectivity is provided, but robustness and scalability are insufficient

Engineering Contradiction:

Improveconnectivity robustnessVSAvoidnetwork scalability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic mobility management where the network architecture adapts to moving nodes through real-time location tracking, dynamic route optimization, and flexible handover mechanisms between access points, enabling the system to scale from static to highly mobile scenarios

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The communication network is designed to universally support both static and moving nodes through a unified architecture that provides consistent connectivity services, allowing the same infrastructure to serve diverse node types without requiring separate specialized systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Area of stationary object

If mobile access points are deployed to support moving nodes, then connectivity coverage is improved, but energy consumption increases

Engineering Contradiction:

Improvenetwork coverage areaVSAvoidaccess point power consumption

Core Design Contradiction:

Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

Mobile access points operate in periodic cycles of active transmission and low-power states, activating only when nodes require service within their coverage area and transitioning to sleep mode otherwise, reducing overall energy consumption while maintaining coverage availability

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system implements self-service through automated node discovery, dynamic access point activation, and intelligent routing that reduces the need for continuous high-power transmission by efficiently matching nodes with appropriate access points based on real-time conditions

Inventive Principle:

Principle #25Self-service

3Reliability

If complex mobility management is implemented for seamless handovers, then connectivity reliability is improved, but system complexity increases

Engineering Contradiction:

Improvemobility management reliabilityVSAvoidhandover management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

A centralized mobility management entity acts as an intermediary that coordinates handovers between access points, absorbing the complexity of seamless connectivity management while presenting simplified interfaces to individual nodes, thereby maintaining reliability without burdening the network with distributed complexity

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If multi-network OBUs are used to create vehicular mesh networks, then network resilience is improved, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The OBU functionality is segmented into modular components that can be independently managed and activated, allowing the system to implement complex mesh networking capabilities while maintaining manageable device complexity through functional decomposition and selective activation of network interfaces

Inventive Principle:

Principle #1Segmentation
