Dynamic Time Slot Selection for TSCH Communication Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Time-Slotted Channel Hopping (TSCH) communication systems, the efficiency of data transmission and reception is compromised due to fixed time slot lengths, which either lead to underutilization when slots are too short or inefficiency when they are too long, necessitating fragment processing and increased overhead.
Innovation Solution
A communication apparatus that dynamically selects between schedules with varying time slot lengths, starting them at the same time, allowing transmission and reception nodes to switch between short and long time slots based on data length, ensuring optimal slot usage without interrupting data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a small slot length is used, then communication efficiency is enhanced for small data lengths, but communication efficiency declines for large data lengths requiring fragment processing
Solution Approach 1:
The patent implements multiple schedules with different slot lengths that can be dynamically selected based on data characteristics. The system transitions from a fixed slot length to a dynamic selection mechanism where the appropriate schedule (with suitable slot length) is chosen according to the data length and communication requirements, thereby optimizing efficiency while avoiding unnecessary fragment processing
Solution Approach 2:
The patent changes the parameter of slot length by providing multiple schedules with varying slot lengths. Instead of using a single fixed slot length, the system offers a set of schedules with different slot length parameters, allowing the communication apparatus to select the most appropriate one for the current communication scenario, thus resolving the contradiction between efficiency for small data and avoiding fragmentation for large data
2Device complexity
If a large slot length is used, then large data can be transmitted without fragment processing, but communication efficiency declines for small data lengths
Solution Approach 1:
The system dynamically selects between schedules with different slot lengths based on the actual communication needs. When small data needs to be transmitted, a schedule with smaller slot length is selected to maintain efficiency. When large data needs to be transmitted, a schedule with larger slot length is selected to avoid fragment processing, thus dynamically adapting to different scenarios
Solution Approach 2:
The patent provides multiple schedules with different slot length parameters. By changing the slot length parameter according to the data characteristics, the system can optimize communication efficiency for small data while avoiding fragment processing overhead for large data, effectively resolving the contradiction

AI summary
According to one embodiment, a communication apparatus includes one or more processors. The one or more processors select any schedule from among a plurality of schedules having processing units of data different from each other that are to be used for communication using a time-division multiplex method, based on an attribute of data. The one or more processors control transmission and reception of data according to the selected schedule.
