Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks are inadequate in supporting complex arrays of both moving and static nodes, such as those found in the Internet of Moving Things, as they fail to provide robust, scalable, and efficient connectivity and services across diverse environments with varying mobility and density of devices.
Innovation Solution
A communication network architecture that includes a platform capable of providing always-on, secure, and energy-efficient connectivity to both mobile and static things, utilizing a cloud-based service-oriented architecture with mobile access points and multi-network on-board units (OBUs) to form a mesh of communication links, enabling flexible configuration and adaptation to different environments and use cases.
Engineering Contradictions & Design Principles
Engineering 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
Solution Approach 1:
The network architecture dynamically adapts to changing environments by allowing access points to transition between fixed and mobile states, and by enabling real-time reconfiguration of network parameters based on device density and mobility patterns, thereby achieving both robustness and adaptability
Solution Approach 2:
The system uses universal access point interfaces that can function in both fixed and mobile configurations, allowing the same hardware and software platform to serve diverse environments (vehicles, portable devices, fixed installations) without requiring specialized components for each scenario
2Adaptability or versatility
If network coverage is expanded to diverse environments, then adaptability improves, but energy consumption increases
Solution Approach 1:
Mobile access points employ periodic wake-up and sleep cycles, activating only when devices are detected in proximity and entering low-power mode when idle, thereby maintaining broad environmental coverage while significantly reducing average energy consumption compared to continuous operation
Solution Approach 2:
The system performs self-adaptive power management where access points autonomously adjust their operational states based on local device density and network conditions, eliminating the need for centralized power control and enabling energy-efficient operation across diverse environments
3Reliability
If secure connectivity is provided across all devices, then reliability improves, but system complexity increases
Solution Approach 1:
The system introduces a centralized authentication server as an intermediary that handles all security operations (device registration, credential verification, session management), allowing individual access points to maintain simple implementations while the network as a whole achieves robust security through the mediating authentication infrastructure

AI summary
A request from a mobile access point that is installed on a vehicle may be received via network interface circuitry of one or more computing devices. Processing circuitry of the one or more computing devices may determine characteristics of a captive portal to present in response to the request based on current location of the vehicle and mobile access point. A captive portal with the determined characteristics is then provided by the processing circuitry, via the network interface circuitry, in response to the request.
