Crowdsourced IoT Roaming via Lightweight UE Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crowdsourced IoT solutions are designed as one-organization architectures, limiting interoperability and preventing roaming between different organizations, which restricts coverage and functionality.
Innovation Solution
A crowdsourced IoT solution that enables roaming between different instances of a crowdsourced IoT network by implementing a lightweight authorization mechanism in User Equipment (UE) devices, allowing transmitting devices to roam from one organization to another while controlling permissions at the organization level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a one-organization architecture is used for crowdsourced IoT, then the system is simpler to implement, but interoperability between different organizations is limited and roaming is prevented
Solution Approach 1:
The system is segmented into multiple organizational instances, each operating as an independent crowdsourced IoT network. The UE device maintains separate roaming permission data structures for different organizations, allowing independent management of interoperability rights while maintaining overall system functionality through standardized communication protocols.
Solution Approach 2:
A roaming permission data structure acts as an intermediary mechanism between different organizational instances. This data structure stores and manages authorization information that enables UEs to determine whether they are permitted to access and report data for transmitting devices from other organizations, facilitating controlled interoperability.
2Area of stationary object
If roaming between different organizational networks is enabled, then IoT coverage is extended, but authorization and permission management becomes more complex
Solution Approach 1:
Roaming permissions are predetermined and stored in the UE device's data structure before actual roaming occurs. The system pre-configures which transmitting devices and organizations are authorized for roaming, eliminating the need for real-time authorization negotiations and reducing the complexity of permission management during active roaming operations.
Solution Approach 2:
The UE device autonomously determines whether roaming is permitted by checking its internal data structure against the transmitting device's organization identifier. This self-service authorization mechanism eliminates the need for complex real-time authentication protocols, allowing the device to independently make roaming decisions based on pre-configured permissions.
3Measurement precision
If continuous monitoring of all transmitting devices is performed, then location accuracy is improved, but battery consumption increases
Solution Approach 1:
The UE device performs partial monitoring by selectively processing only those transmitting devices for which it has roaming permissions configured in its data structure. Instead of continuously monitoring all transmitting devices in range, the device filters processing to only authorized targets, reducing energy consumption while maintaining location tracking accuracy for permitted devices.
Solution Approach 2:
The monitoring function is optimized by applying different processing quality levels based on the transmitting device's organization. Devices with configured roaming permissions receive full monitoring and location tracking, while devices without permissions are ignored entirely. This local quality differentiation reduces overall energy consumption while maintaining precision where needed.
Data Source
AI summary
A crowdsourced Internet of Things (IoT) solution is described. A user equipment (UE) receives a message from a transmitting device which is associated with a first organization while the user equipment is associated with a second organization. The UE determines whether roaming is allowed for the transmitting device from the first organization to the second organization. If roaming is allowed, the UE transmits at least an identifier of the transmitting device and location information of the UE to a roaming exchange for transmission to an IoT platform of the first organization. If roaming is not allowed, the UE ignores the message from the transmitting device.
