IoT Alias-Based Time-Limited Lease Addressing for Dynamic Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT networks, especially in fog and edge networks, the increasing number of transient IoT devices leads to increased time for lookups and connection establishment, which is problematic for mission-critical use cases, as traditional address translation methods become inefficient due to lengthy device IDs and growing databases.
Innovation Solution
Implementing alias-based time-limited lease addressing, where reusable shortcodes or aliases are used instead of lengthy device IDs, allowing for faster packet transmission and reduced processing overhead by mapping node identifiers to a shortcode table, with the ability to assign and rank aliases based on device behavior, priority, and activity levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional address translation methods are used with lengthy device IDs, then device identification is accurate, but lookup time and connection establishment time increase significantly
Solution Approach 1:
The patent introduces an alias address as an intermediary between the device's original lengthy ID and the translation database. This alias acts as a short-term cache that eliminates repeated lookups of the same device, thereby reducing lookup time while maintaining accurate device identification through the original ID when needed.
Solution Approach 2:
The system performs preliminary action by pre-assigning alias addresses to devices before they need to be looked up. The alias is established in advance and stored in the translation database, so when the device communicates, the alias is already ready for immediate use without requiring real-time resolution of the lengthy original ID.
2Adaptability or versatility
If traditional address translation methods are used with growing databases of device IDs, then comprehensive device coverage is achieved, but processing overhead and transaction time increase
Solution Approach 1:
The patent segments the device identification system into two parts: the original lengthy device ID for comprehensive identification and a shortened alias address for rapid transactions. This segmentation allows the system to maintain complete device coverage through the original ID while improving transaction speed by using the segmented alias for repeated operations.
Solution Approach 2:
The system creates a copy of the device identification function by introducing alias addresses that represent devices. These alias copies are stored in the translation database and can be used instead of the original lengthy IDs, reducing processing overhead while maintaining the ability to identify and track all devices comprehensively.
3Loss of time
If reusable shortcodes are implemented, then lookup efficiency improves, but address management complexity increases
Solution Approach 1:
The alias address system implements dynamics by allowing aliases to be created, reused, and invalidated based on device activity. Aliases are dynamically assigned to active devices and can be reclaimed when devices become inactive, enabling the system to adapt to changing network conditions while maintaining simple management through automated lifecycle handling.
