Server Low Power Communication via MTU Packet Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In periodical data communication, the frequent transmission of data increases power consumption in devices operating on limited power sources, such as batteries, reducing the operational time for main functions.
Innovation Solution
A server method that adjusts the number of data transmission times by generating packets using a maximum transmission unit (MTU) and allowable delay times for each service, storing data when delay times exceed thresholds, and transmitting in bulk when the number of items reaches the MTU, thereby reducing unnecessary transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is constantly transmitted at a minimum transmission period, then data communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic data transmission with dynamically adjustable transmission periods. Instead of constant minimum-period transmission, the system transmits data periodically at optimized intervals that balance reliability requirements with power consumption constraints, allowing the terminal to sleep between transmission periods.
Solution Approach 2:
The server performs preliminary actions by predicting which data items will be transmitted next and pre-notifying the terminal about upcoming transmissions. This allows the terminal to wake up in advance to receive data, rather than continuously monitoring or transmitting at minimum intervals, thereby reducing power consumption while maintaining communication reliability.
2Quantity of substance
If the number of transmission times is increased, then data communication completeness is improved, but power consumption increases
Solution Approach 1:
The patent merges multiple data items into single transmission packets. The server aggregates multiple data items that would otherwise require separate transmissions, and the terminal receives these combined packets in fewer transmission events. This reduces the total number of transmission times while maintaining complete data delivery, directly addressing the contradiction between transmission completeness and power consumption.
3Speed
If data is transmitted at minimum transmission period, then communication responsiveness is improved, but operational time for main functions decreases
Solution Approach 1:
By implementing periodic transmission with extended intervals between periods, the terminal can dedicate more time to main functions during sleep intervals while maintaining communication responsiveness during active periods. The optimized periodic schedule ensures critical data is transmitted promptly while allowing substantial operational time for main functions.
Solution Approach 2:
The server's preliminary notification mechanism allows the terminal to prepare for and efficiently handle data transmissions during brief wake periods, then return to main functions. This preliminary alert system maintains communication responsiveness without requiring continuous operation, thereby preserving operational time for main functions.

AI summary
Provided is a server for performing a low power communication and an operation method of the server that may generate a packet including collected data based on a maximum number of data items transmitted based on a maximum transmission unit (MTU) established between a client and the server and an allowable delay time of at least one service, and may transmit the generated packet to the client.
