Distributed Edge Control Device for IoT Sensor Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IoT systems, as the number of monitoring cameras increases, the load and communication burden on a centralized server become excessive, leading to potential delays and inaccuracies in data transmission, especially when sensing targets move beyond the range of individual sensors or access points.
Innovation Solution
Implementing a distributed processing mechanism where edge servers, located on the local network side between the internet and local networks, manage and transmit information from sensor devices to other edge servers associated with different cells, reducing communication load and enabling continuous service provision without delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centralized server is used to integrate and process sensing information from multiple sensor devices, then service integration and processing capability are improved, but communication load and server burden increase excessively
Solution Approach 1:
The patent divides the centralized server architecture into multiple distributed edge servers, each responsible for processing sensing information from sensor devices within its own cell. This segmentation reduces the communication load on any single server while maintaining overall service processing capability through distributed operation.
Solution Approach 2:
The patent introduces a hierarchical dimension to the system architecture, with edge servers operating at the local cell level and a master server coordinating at the higher level. This dimensional change allows processing to occur closer to the data source, reducing communication load while preserving integration capabilities.
2Area of stationary object
If the number of monitoring cameras is increased to expand sensing range, then coverage area is improved, but server load and communication burden increase
Solution Approach 1:
The patent segments the system into multiple cells, each with its own edge server managing sensor devices within that cell. This allows the sensing coverage area to be expanded by adding more cells and edge servers without proportionally increasing the communication load on a single centralized server, as each edge server handles its own cell's data independently.
3Productivity
If sensing information is transmitted to a centralized server on the internet side, then data processing capability is improved, but communication latency increases
Solution Approach 1:
The patent implements preliminary action by having edge servers process sensing information locally within their own cells before any potential transmission to the master server. This preliminary local processing reduces communication latency by eliminating the need to transmit all data across the entire network, while still maintaining the data processing capability through distributed edge server operation.
Data Source
AI summary
There is provided a mechanism capable of processing a service using a plurality of sensor devices in a distributed manner while suppressing a communication load and providing the service. A control device is arranged on a local network side with respect to a gateway between an internet and a local network. The control device includes: a control unit configured to transmit or receive information regarding one or more sensor devices wirelessly connected to a first cell associated with the control device to or from another control device associated with a second cell.
