Distributed Deployment Device for Sensor Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies for distributed deployment in sensor networks face inefficiencies when event generation situations change over time, leading to increased network traffic and load on server nodes, as they rely solely on traffic reduction or load balancing without considering dynamic changes in event occurrence.
Innovation Solution
A distributed deployment device that includes an event collecting unit, a generation event information collecting unit, a deployment destination determining unit, a traffic reduction amount collecting unit, an event collection cost calculating unit, and an event information transmission interval control unit, which dynamically determines the optimal node for module deployment and adjusts transmission intervals based on traffic reduction and collection costs.

Engineering Contradiction Analysis
1Productivity
If distributed deployment is performed based on traffic reduction effect or load on processing device, then network traffic and server load are reduced, but efficient distributed deployment becomes impossible when event generation situation changes
Solution Approach 1:
The patent implements dynamic distributed deployment by continuously monitoring event generation situations and adjusting module deployment locations accordingly. The system evaluates event logs in real-time and redistributes modules to nodes where events are currently occurring, rather than using static deployment based solely on initial traffic reduction calculations. This dynamic approach maintains both deployment efficiency and adaptability to changing event patterns.
Solution Approach 2:
The system employs feedback mechanisms by collecting and analyzing event logs to determine whether event generation situations have changed. Based on this feedback, the system automatically adjusts module deployment decisions. The feedback loop includes monitoring event occurrences, detecting changes in event generation patterns, and triggering redeployment actions to maintain optimal distributed deployment efficiency while adapting to new situations.
2Adaptability or versatility
If the time interval for evaluating event logs is shortened to prevent inefficiencies, then adaptability to event generation changes is improved, but collection cost of event logs increases
Solution Approach 1:
The system applies partial evaluation by selectively analyzing event logs based on change detection criteria rather than evaluating all logs at fixed short intervals. The system performs evaluation only when necessary - when there is evidence of event generation situation changes - thereby reducing the overall collection and processing cost while maintaining responsiveness to actual changes. This avoids the excessive action of continuous short-interval evaluation when no changes occur.
Solution Approach 2:
The system dynamically adjusts the evaluation interval parameter based on detected event generation patterns. When changes are detected, the system shortens the evaluation interval to improve responsiveness. When patterns are stable, the system extends the interval to reduce collection costs. This parameter adaptation allows the system to achieve both responsiveness and cost efficiency by matching the evaluation frequency to the actual event dynamics.
