Content Retrieving Agent for Mobile Energy Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Internet architecture, based on location-based addressing, leads to inefficient energy consumption in mobile devices when retrieving large content due to continuous receiver activation, especially during prolonged data transfers, which drains battery life.
Innovation Solution
A mobile device designates a content-retrieving agent, typically a stationary device, to obtain and store content on its behalf, allowing the mobile device's receiver to enter an energy-saving sleep mode, waking up only to receive the content, thus extending battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile device's receiver remains continuously activated to retrieve content, then the content retrieval reliability is improved, but the energy consumption increases
Solution Approach 1:
The content-retrieving agent performs preliminary actions by obtaining and caching content on behalf of the mobile device before the device needs to receive it. The agent proactively retrieves content from remote devices, stores it locally, and prepares it for transfer, allowing the mobile device to remain in sleep mode and wake only when ready to receive already-prepared content.
Solution Approach 2:
A content-retrieving agent is introduced as an intermediary between the mobile device and remote content sources. This agent handles the energy-consuming content retrieval operations, while the mobile device only performs lightweight operations of sending requests and receiving final content, significantly reducing its energy consumption while maintaining retrieval reliability.
2Speed
If the mobile device receives content directly from remote devices, then the content retrieval speed is improved, but the battery life decreases
Solution Approach 1:
The content-retrieving agent performs preliminary content acquisition and local caching, so when the mobile device wakes from sleep mode, the content is already available for immediate transfer. This eliminates waiting time and maintains fast content delivery while allowing the device to remain powered off for extended periods.
Solution Approach 2:
The content-retrieving agent serves as an intermediary that handles the time-consuming content retrieval process, allowing the mobile device to minimize its active duration. The agent manages the lengthy operations of content acquisition and caching, while the device only needs to be active briefly for request transmission and content reception.
3Productivity
If the mobile device performs content lookup and retrieval operations, then the content access efficiency is improved, but the energy consumption increases
Solution Approach 1:
The energy-intensive content lookup and retrieval operations are extracted from the mobile device and delegated to the content-retrieving agent. The device only performs minimal operations of sending content name requests and receiving results, while the agent handles the computationally expensive lookup and content acquisition tasks remotely.
Solution Approach 2:
The content-retrieving agent acts as an intermediary that performs content lookup and retrieval operations on behalf of the mobile device. This intermediary handles the energy-consuming productivity-critical operations, allowing the mobile device to maintain high content access efficiency while consuming minimal energy.

AI summary
One embodiment of the present invention provides a system including a mobile device (402) and a content-retrieving agent (404) for facilitating energy-efficient content retrieval. During operation, the mobile device receives (408) a request for a piece of content from a user. In response to the request, the mobile device forwards (410) the request to the content-retrieving agent (404) which is configured to obtain the requested content from a remote device (406) on behalf of the mobile device. The system allows the mobile device's receiver to be placed (412) in an energy-saving sleep mode when the content-retrieving agent is obtaining the requested content for the mobile device and is not transmitting the content to the mobile device. The system allows the mobile device's receiver to wake up (426) when the content-retrieving agent is transmitting the content to the mobile device. The mobile device receives the content from the content-retrieving agent.
