Wireless Packet Transmission Timing Optimization

Solution Overview

Problem

Wireless devices face resource consumption and battery power expenditure when re-establishing communication channels to transmit packets, especially if the channel is expected to be torn down during a scheduled transmission time window, leading to inefficient resource utilization and potential packet re-sending.

Innovation Solution

A method that identifies a time window for packet transmission and transmits the packet either before or after the expected channel teardown, based on estimated resource utilization, allowing the channel to be torn down and re-established late in the window to minimize resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the communication channel is re-established to transmit a packet, then the packet can be transmitted, but network resources are consumed and battery power is expended

Engineering Contradiction:

Improvepacket transmission reliabilityVSAvoidbattery power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary assessment of channel availability before packet transmission. By checking whether the channel is expected to be torn down during the time window and estimating resource utilization, the system proactively decides on transmission timing, avoiding unnecessary channel re-establishment and reducing battery power consumption

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts packet transmission timing based on real-time channel conditions and resource availability estimates. Instead of fixed transmission schedules, the system flexibly selects transmission moments within the time window, optimizing the balance between reliable delivery and resource conservation

Inventive Principle:

Principle #15Dynamics

2Reliability

If the communication channel is re-established to transmit a packet, then the packet can be transmitted, but time is required to establish the channel

Engineering Contradiction:

Improvepacket transmission reliabilityVSAvoidchannel establishment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary assessment of channel availability before packet transmission. By checking whether the channel is expected to be torn down during the time window and estimating resource utilization, the system proactively decides on transmission timing, avoiding unnecessary channel re-establishment and reducing time loss

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the packet is transmitted early in the time window, then the transmission can proceed, but resources may be wasted if the channel is torn down later

Engineering Contradiction:

Improvetransmission speedVSAvoidresource utilization efficiency

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The system dynamically adjusts packet transmission timing based on real-time channel conditions and resource availability estimates. Instead of fixed transmission schedules, the system flexibly selects transmission moments within the time window, optimizing the balance between transmission speed and resource efficiency

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system uses feedback from channel condition monitoring and resource utilization estimation to adjust transmission decisions. By continuously assessing whether the channel is expected to be torn down and estimating resource utilization, the system refines transmission timing to avoid wasted resources while maintaining productivity

AI summary

A system and method of transmitting packets from a wireless device is provided. According to a broad aspect, the wireless device is to transmit a packet on a communication channel during a time window based on whether or not the communication channel is expected to be torn down during the time window. If the communication channel is not expected to be torn down during the time window, then the wireless device transmits the packet late in the time window. However, if the communication channel is expected to be torn down during the time window, then the wireless device transmits the packet during the time window just prior to when the communication channel is expected to be torn down. This prevents having to re-establish the communication channel merely to transmit the packet if the communication channel is torn down.
