Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT data transmission between AP IoT servers and edge gateway devices results in significant greenhouse gas emissions due to power consumption, which is influenced by data transfer rates, geographic locations, and the number of transmission hops.
Innovation Solution
An IoT edge gateway device location optimization system adjusts the geographic placement of edge gateway devices relative to AP IoT servers to minimize power consumption and CO2 emissions by determining optimal locations based on power consumption metrics and CO2 emissions per unit distance, and dynamically repositions devices to maintain efficiency as data transfer volumes change.

Engineering Contradiction Analysis
1Area of stationary object
If IoT edge gateway devices are placed farther from AP IoT servers to cover wider areas, then the coverage area is improved, but power consumption and CO2 emissions increase
Solution Approach 1:
The system changes the geographic parameter (location) of edge gateway devices to optimize the balance between coverage area and power consumption. By calculating optimal locations based on distances to multiple AP IoT servers and their associated CO2 emissions data, the system determines positions that minimize total emissions while maintaining adequate coverage.
Solution Approach 2:
The system creates multiple edge gateway devices at different geographic locations to replicate the gateway function across multiple sites. This allows the network to cover larger areas by distributing multiple gateways rather than relying on a single distant gateway, thereby reducing the distance and emissions for each individual gateway-AP connection.
2Area of stationary object
If more transmission hops are used to reach remote AP IoT servers, then geographic coverage is extended, but power consumption and CO2 emissions increase
Solution Approach 1:
The system introduces intermediate edge gateway devices that act as mediators between AP IoT servers and the central network. By placing these intermediary gateways strategically near AP servers, data can be transmitted over shorter distances with fewer hops, reducing the cumulative energy consumption and CO2 emissions associated with long transmission paths.
3Loss of energy
If edge gateway devices are positioned closer to AP IoT servers to reduce emissions, then power consumption decreases, but the number of required devices increases
Solution Approach 1:
The system uses parameter optimization by calculating the exact optimal location for each edge gateway device based on the geographic positions of AP IoT servers and their respective CO2 emissions factors. This mathematical optimization determines the minimum number of devices needed and their precise locations to achieve the lowest possible total emissions, avoiding unnecessary device proliferation.
Solution Approach 2:
The system dynamically determines the optimal number and locations of edge gateway devices based on real-time conditions including data transfer volumes, distances to AP servers, and CO2 emissions factors. This dynamic optimization allows the system to adapt the device configuration to current network demands, deploying additional devices only when and where necessary to maintain emission efficiency.
