IoT Communication Scheduler for Traffic Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems struggle to manage short-cycle data collection from IoT sensors, as they are not capable of handling frequent data transmission and often result in network congestion and interference, especially when users have limited knowledge about network management and development.
Innovation Solution
A method is introduced that includes a reservation unit in a communication system to determine absolute transmission times for IoT terminals, avoiding interference by adjusting the offset of transmission cycles, allowing users to specify only the cycle and not the offset, thereby improving line utilization efficiency and simplifying network management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to freely define the use of a communication path, then application development flexibility is improved, but traffic concentration and network congestion occur
Solution Approach 1:
The patent introduces a scheduler as an intermediary component that mediates between user applications and the communication network. The scheduler receives transmission requests from applications, determines appropriate transmission timings based on network state, and controls when data is actually transmitted. This intermediary layer allows applications to develop freely without needing to understand network constraints, while the scheduler prevents traffic concentration by distributing transmissions across different time slots.
Solution Approach 2:
The scheduler performs preliminary analysis of network traffic patterns and predetermined light traffic time slots before actual data transmission occurs. By analyzing historical traffic data and identifying periods of low network utilization in advance, the scheduler can pre-determine optimal transmission timings for IoT devices, thereby preventing traffic concentration before it happens while maintaining application development flexibility.
2Object-affected harmful factors
If IoT traffic is transmitted in light traffic time slots, then network interference is reduced, but real-time communication capability is degraded
Solution Approach 1:
The patent implements dynamic scheduling that adapts to different communication requirements. The scheduler can dynamically adjust transmission timing based on the type of traffic: for non-real-time IoT data, it schedules transmissions during light traffic periods to minimize interference; for real-time communication requirements, it can override the light traffic schedule and allocate resources immediately. This dynamic approach resolves the contradiction by making the system flexible enough to handle both scenarios appropriately.
3Productivity
If transmission timing is predetermined based on light traffic periods, then line utilization efficiency is improved, but device complexity increases
Solution Approach 1:
The scheduler is designed to autonomously determine transmission timings without requiring complex user configuration or manual network management. It automatically analyzes network traffic patterns, identifies light traffic periods, and assigns transmission slots to IoT devices based on this analysis. This self-service capability improves line utilization efficiency while keeping the system relatively simple, as the scheduler handles the complexity internally without burdening users or requiring complex device-side logic.

AI summary
To improve line utilization efficiency in short-cycle data collection, it is provided a method of managing communication in a communication system, the communication system including: an aggregation unit configured to receive information through a communication path from a plurality of terminals, which are sources of information transmission; and a reservation unit configured to determine, for each of the plurality of terminals, timing at which the terminal transmits a signal, the method comprising steps of: receiving, by the reservation unit, a relative time specified by a user as a time at which the terminal transmits the information; and determining, by the reservation unit, as scheduling information, an absolute time unique throughout the communication system so that interference with another communication session is avoided when the terminal holds communication at the relative time.
