Network Node Multi-State Operation for Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face challenges in reducing energy consumption while ensuring reliable data transmission with low latency, as network nodes often operate in states that consume excessive energy for both control and data signal exchanges.
Innovation Solution
The network node operates in three distinct states: an energy-minimal first state where no signals are exchanged, a second state where only control signals are handled, and a third state for data transmission, allowing dynamic switching based on control signals to minimize energy usage and optimize participation in network communications.

Engineering Contradiction Analysis
1Reliability
If network nodes continuously operate in a state capable of receiving and transmitting both control and data signals, then reliable data transmission with low latency is ensured, but energy consumption increases significantly
Solution Approach 1:
The network node dynamically switches between different operating states (first state with minimal energy consumption, second state for control signal reception, third state for data transmission) based on current network conditions and requirements, rather than maintaining a fixed high-energy operational state continuously
Solution Approach 2:
The network node periodically transitions between low-power sleep states and active transmission states based on scheduled time slots, enabling energy-efficient operation while maintaining network functionality through periodic activation for control and data signal exchanges
2Use of energy by moving object
If network nodes switch to low energy consumption states frequently, then energy efficiency is improved, but response time for data transmission increases
Solution Approach 1:
The network node performs preliminary actions by staying in the second operating state (capable of receiving control signals) during time slots when only control signals are transmitted, allowing rapid transition to the third state for data transmission without requiring full wake-up from the first state, thus reducing response latency while maintaining energy efficiency
Solution Approach 2:
The network node dynamically adjusts its operational state based on real-time network conditions, transitioning between states with optimized response times for different signal types, balancing energy consumption and latency requirements
3Use of energy by moving object
If network nodes operate in multiple operating states with different functionalities, then energy consumption is reduced, but device complexity increases
Solution Approach 1:
The network node uses feedback mechanisms where control signals received in the second operating state provide information about upcoming data transmission requirements, enabling the node to proactively transition to the third state in advance, thereby simplifying state management while maintaining energy efficiency and low latency

AI summary
A network node (1, 2, 3, 4, 5, 6) for a communication network (7) is set up to send data signals, its operation being at least partially controllable by external control signals.The network node (1, 2, 3, 4, 5, 6) is configured to alternately assume a first operating state (I) in which control signals and data signals from the network node (1, 2, 3, 4, 5, 6) are neither receiveable nor transmittable; a second operating state (II) in which control signals from the network node (1, 2, 3, 4, 5, 6) are at least receiveable, wherein the network node (1, 2, 3, 4, 5, 6) switches from the first operating state (I) to the second operating state (II) upon the occurrence of a transition condition; and a third operating state (III) in which data signals from the network node (1, 2, 3, 4, 5, 6) are transmittable, wherein the network node (1, 2, 3, 4, 5, 6) switches from the first operating state (I) to the second operating state (II) upon receiving a corresponding control signal from the second operating state. (II) changes to the third operating state (III).
