Solution Overview

Problem

Conventional wireless communication terminals face challenges in reducing the likelihood of battery depletion during collaborative content acquisition in content-oriented networks, as they often prioritize power-saving methods that may lead to higher battery drain in nearby terminals.

Innovation Solution

A wireless communication terminal that transmits interest packets requesting content indices and battery level information, determining whether to use proximity or infrastructure communication based on the battery levels of both the terminal and nearby devices, thereby optimizing power usage and reducing the risk of battery exhaustion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a wireless communication terminal uses proximity communication to acquire content from nearby terminals, then power consumption is reduced compared to infrastructure communication, but the battery of nearby terminals may be depleted

Engineering Contradiction:
Improvepower consumptionVSAvoidbattery depletion risk
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system implements feedback by having terminals report their battery status to the network, and the network uses this information to dynamically adjust content acquisition routing decisions. Terminals with low battery are identified through feedback mechanisms, and the system responds by alternative routing through infrastructure communication or other terminals with sufficient battery capacity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The content acquisition path is made dynamic rather than static. The system continuously monitors battery status and adjusts the communication path in real-time, switching between proximity communication and infrastructure communication based on current battery conditions of involved terminals.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the terminal prioritizes using infrastructure communication to ensure stable content acquisition, then reliability of content acquisition is improved, but power consumption increases

Engineering Contradiction:
Improvecontent acquisition stabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system changes the parameter of communication mode selection based on battery status. When nearby terminals have sufficient battery, proximity communication is used; when battery is low, the system transitions to infrastructure communication or selects other terminals with adequate battery capacity.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If the terminal requests content from multiple nearby terminals simultaneously, then content acquisition speed is improved, but the likelihood of battery depletion in nearby terminals increases

Engineering Contradiction:
Improvecontent acquisition speedVSAvoidbattery depletion risk
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system applies different selection criteria to different nearby terminals based on their individual battery status. Terminals with high battery capacity are selected as content sources, while terminals with low battery are excluded from being requested, creating a localized quality filter in the content acquisition process.

Inventive Principle:
Principle #3Local quality

AI summary

A wireless communication terminal includes a processor; and a non-transitory memory storing thereon a program which is executed by the processor, the program causing the processor to: transmit a first interest packet requesting transmission of an index of content to a plurality of communication devices via a content-oriented network; receive a first data packet from a first communication device among the plurality of communication devices in response to the first interest packet, wherein the first data packet includes i) the index and ii) first remaining battery level information indicating a remaining battery level of the first communication device, and determine to transmit to the first communication device a second interest packet requesting for transmission of the content to the wireless communication terminal when it is determined that the first remaining battery level information is more than a predetermined threshold value.
