Adaptive Hop Patterns for Low-Latency Telegram Splitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telegram splitting transmission methods in IoT sensor networks suffer from high latency due to pauses between sub-packets, making them unsuitable for applications where low latency is critical, such as pipe bursts or security monitoring in crisis areas.
Innovation Solution
Implementing different classes of hop patterns with varying latency and interference immunity, including reducing pauses between sub-packets, varying the number of sub-packets, increasing bandwidth, using different data rates or modulation methods, and combining normal and low-delay patterns to optimize transmission for specific applications.

Engineering Contradiction Analysis
1Reliability
If telegram splitting transmission method is used to increase transmission reliability in interference-prone channels, then transmission reliability is improved, but latency increases due to pauses between sub-packets
Solution Approach 1:
The patent applies dynamics by making the hop pattern adaptable and configurable rather than fixed. The system can dynamically select between normal hop patterns (for high reliability) and low-delay hop patterns (for low latency) based on application requirements. This is achieved through configurable parameters that allow the transmission system to adjust its behavior in real-time, resolving the contradiction between reliability and latency by making the trade-off adjustable rather than fixed
Solution Approach 2:
The patent applies parameter changes by modifying the hop pattern parameters to create different transmission modes. By changing parameters such as pause duration between sub-packets, number of sub-packets, bandwidth allocation, and data rate, the system can optimize for either reliability or latency as needed. The low-delay hop pattern specifically reduces pause durations and adjusts other parameters to minimize latency while maintaining acceptable reliability through alternative mechanisms
2Ease of operation
If uncoordinated channel access (ALOHA) is used to simplify network operation, then ease of operation is improved, but interference between transmissions increases
Solution Approach 1:
The patent applies the intermediary principle by introducing the hop pattern as a mediating structure that organizes uncoordinated access. Rather than implementing complex coordination protocols that would reduce ease of operation, the hop pattern serves as an intermediary mechanism that structures transmissions in time and frequency domains. This allows nodes to independently select and use hop patterns without centralized coordination, while the pattern itself provides interference mitigation through time-frequency diversity and pause mechanisms

AI summary
The embodiments form a transmission method. The method comprises a step of transmitting class 1 data from a data transmitter to a data receiver, wherein the class 1 data is transmitted in a manner in which it is divided into a first plurality of sub-data-packets using a first hopping pattern. The method also comprises a step of transmitting class 2 data from the data transmitter or another data transmitter to the data receiver, wherein the class 2 data is transmitted in a manner in which it is divided into a second plurality of sub-data-packets using a second hopping pattern. In addition, non-transmission periods between sub-data-packets that are transmitted according to the first hopping pattern are smaller than non-transmission periods between sub-data packets that are transmitted according to the second hopping pattern.
