Wireless Network Addressing System Using Short Node IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the need for long node IDs in each packet transmission results in significant overhead, especially in IoT operations where data bursts are small, due to the inclusion of 48 bits-long receiver and transmitter IDs, which can account for 25%-37.5% of the packet size.
Innovation Solution
The proposed addressing system generates a short node identifier for dedicated communication between devices, which is included in the control part of a communication packet, while maintaining a long node ID for security procedures, thereby reducing overhead and supporting Hybrid automatic-repeat request (HARQ) operations without central allocation or coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If long node IDs (48 bits) are used in each packet transmission to ensure unique identification and security, then identification reliability and security are improved, but transmission overhead increases significantly
Solution Approach 1:
The patent divides the identification function into two separate ID types: short IDs (first node ID) for packet transmission and long IDs (second node ID) for security procedures. This segmentation allows each ID to be optimized for its specific purpose, reducing overall overhead while maintaining reliability and security.
Solution Approach 2:
The patent applies different identification lengths to different functional contexts: short IDs are used locally for packet routing and transmission control, while long IDs are used for security-critical operations. This local quality optimization ensures that the longer IDs are only used where necessary, minimizing overall transmission overhead.
2Productivity
If short node IDs are used to reduce transmission overhead, then transmission efficiency is improved, but identification uniqueness and security may be compromised
Solution Approach 1:
The patent segments the identification system into two parts: short IDs for efficient packet transmission and long IDs for ensuring uniqueness and security. This allows the system to achieve both transmission efficiency and identification reliability by using the appropriate ID type for each function.
Solution Approach 2:
The short ID acts as an intermediary that enables efficient packet transmission, while the long ID serves as the ultimate guarantee for uniqueness and security. The system uses the short ID for routine operations and falls back to long IDs when security or uniqueness verification is required.
3Reliability
If long node IDs are included in every packet to ensure security procedures, then security is improved, but packet size and transmission time increase
Solution Approach 1:
The patent segments security-related identification from general packet transmission identification. Short IDs are used for packet transmission to minimize size and transmission time, while long IDs are used only for security procedures, thus avoiding the time penalty of transmitting long IDs in every packet.
Solution Approach 2:
The patent applies long IDs locally only to packets that require security procedures, rather than including them in all packets. This localized application of long IDs maintains security where needed while minimizing the impact on overall transmission time.
