IoT Terminal Floor Control via Random Stand-by and Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, particularly in IoT environments, the absence of a terminal with 'floor' authority leads to operational inefficiencies, as there is no designated server to manage data transmission and resolve conflicts over media access.
Innovation Solution
A communication method where terminals request and grant transmission authorization using floor request and grant messages, with priorities and random stand-by times determining which terminal has access to transmit media data, allowing for seamless transitions and conflict resolution without a designated server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a designated server is used to manage data transmission and resolve conflicts, then system reliability and conflict resolution capability are improved, but device complexity and system cost increase
Solution Approach 1:
The patent implements a self-service mechanism where terminals autonomously manage floor acquisition and conflict resolution without requiring a designated server. Each terminal independently generates random stand-by times, monitors for floor grant messages, and resolves conflicts through predefined rules, enabling the system to serve itself rather than relying on external server management
Solution Approach 2:
The patent extracts the server management function from the system by allowing terminals to independently handle floor control operations. Instead of centralizing conflict resolution in a server, the patent removes the server's active management role and distributes the functionality to terminals, which now autonomously acquire and manage floor rights through random stand-by times and monitoring mechanisms
2Productivity
If multiple terminals transmit media data simultaneously, then communication efficiency and data throughput are improved, but network resource wastage and signal interference increase
Solution Approach 1:
The patent applies preliminary action by requiring terminals to generate and set random stand-by times before attempting to transmit media data. This pre-transmission preparation ensures that terminals wait for a predetermined random duration before acquiring the floor, preventing simultaneous transmission attempts and eliminating the need for collision recovery procedures that would waste network resources
Solution Approach 2:
The patent implements a mechanism where terminals that successfully acquire the floor can transmit media data immediately without waiting for acknowledgment or confirmation from other terminals. This rushing through the transmission process eliminates delays and retransmissions, allowing efficient data throughput while the random stand-by time mechanism prevents resource wastage from collisions
3Reliability
If random stand-by times are used for floor acquisition, then conflict resolution and seamless transitions are improved, but transmission delay and response time increase
Solution Approach 1:
The patent implements periodic action through the random stand-by time mechanism, where terminals periodically attempt to acquire the floor by waiting for predetermined random durations. This periodic attempt structure ensures that conflicts are resolved systematically while maintaining seamless transitions, as the random nature of the periods prevents predictable collision patterns and ensures fair access opportunities for all terminals
