Traffic Aggregator for Wireless Power Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with wireless circuitry face challenges in controlling power consumption, especially when multiple applications use wireless communication links independently, leading to excessive battery drain due to continuous radio activity.
Innovation Solution
Implementing traffic aggregators that coordinate and aggregate application traffic from multiple applications, conveying data in periodic bursts to reduce radio activity and conserve power by aligning data transmission with periods of inactivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple applications use wireless communication links independently, then each application can operate autonomously, but power consumption increases due to continuous radio activity
Solution Approach 1:
The patent merges multiple independent application traffic streams into a single aggregated data stream through the traffic aggregator. Multiple applications share a common wireless communication link and radio resource, coordinating their transmissions through the aggregator to avoid simultaneous access conflicts and reduce overall radio activity duration.
Solution Approach 2:
The traffic aggregator implements periodic transmission of aggregated data bursts over the wireless link. Instead of continuous radio operation, data is transmitted in scheduled periodic bursts, allowing the radio to enter low-power states between bursts while maintaining application functionality.
2Use of energy by moving object
If traffic aggregators coordinate and aggregate application traffic, then power consumption is reduced through periodic bursts, but system complexity increases
Solution Approach 1:
The traffic aggregator serves as an intermediary component between multiple applications and the wireless communication link. It mediates traffic coordination, aggregation, and scheduling functions, isolating the complexity from individual applications while enabling power-efficient periodic transmission.
Solution Approach 2:
The traffic aggregator performs multiple functions including traffic aggregation, scheduling, coordination of multiple applications, and management of the wireless link. This multi-functional approach consolidates complexity into a single universal component rather than requiring separate mechanisms for each function.
3Loss of energy
If data is transmitted in periodic bursts, then radio activity is minimized and power is conserved, but data transmission continuity may be affected
Solution Approach 1:
The traffic aggregator performs preliminary actions by buffering and pre-processing data from multiple applications before transmission. Data is collected and prepared in advance during idle periods, then transmitted in coordinated bursts, ensuring continuity is maintained despite periodic transmission patterns.
Solution Approach 2:
While transmission occurs in periodic bursts, the useful action of data processing and aggregation continues continuously. The aggregator maintains continuous monitoring and buffering of application data, ensuring no data is lost during idle radio periods and transmission continuity is preserved at the application level.

AI summary
A system may include a client device running multiple client-side applications and server equipment running multiple server-side applications. One or more traffic aggregators may be provided between the client-side applications and the server-side applications. Each traffic aggregator may aggregate application traffic from the multiple applications to form one or more classes of aggregated data. Interfaces may be provided between the traffic aggregators and the applications to customize application traffic. Traffic aggregators in the system may be dynamically updated.
