Message Queue Bypass for Power-Save Network Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication networks are inefficient in terms of energy consumption, information transfer speed, and bandwidth utilization, particularly when dealing with devices in power-save mode, as they often require devices to wait for packet arrival and contend for medium access, leading to unnecessary energy expenditure and delayed communication.
Innovation Solution
A method and apparatus that allow a networked device to bypass the outgoing message queue and directly transmit messages to a device in power-save mode, determining the power-save capability of the recipient device and adjusting communication protocols to maintain control of the medium without contending with other devices, ensuring timely and energy-efficient communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If devices use conventional message queuing and medium access protocols, then communication reliability is maintained, but energy consumption increases and communication speed decreases
Solution Approach 1:
The patent segments the message transmission process into two distinct paths: conventional queuing for normal traffic and direct transmission for power-save devices. By separating the transmission paths, the system avoids forcing power-save devices to wait in queues, thereby reducing their energy consumption while maintaining communication speed through direct transmission when needed.
Solution Approach 2:
The patent implements dynamic medium access control where the network adapter determines the appropriate transmission method based on the recipient's power-save status. The system dynamically switches between conventional queuing and direct transmission modes, adjusting communication behavior according to device state to optimize both energy efficiency and communication speed.
2Reliability
If devices wait for packet arrival and contend for medium access, then communication protocol compliance is maintained, but energy consumption increases
Solution Approach 1:
The patent introduces a network adapter as an intermediary that manages the communication between senders and power-save devices. The adapter handles medium access control and determines whether to use conventional queuing or direct transmission, thereby maintaining protocol compliance while enabling energy-efficient communication with power-save devices without requiring them to contend for medium access.
Solution Approach 2:
The system performs preliminary identification of power-save devices and pre-establishes direct transmission paths for them. By recognizing power-save devices in advance and preparing direct transmission routes, the system eliminates the need for these devices to wait in queues or contend for medium access, thereby reducing energy consumption while maintaining protocol compliance through controlled medium access.
3Adaptability or versatility
If devices use standard medium access protocols, then communication fairness is maintained, but bandwidth utilization decreases and energy consumption increases
Solution Approach 1:
The patent applies local quality by treating power-save devices differently from normal devices in terms of transmission methodology. While normal devices use conventional queuing and contention-based access, power-save devices receive direct transmission treatment when needed. This differentiated approach optimizes energy efficiency for power-save devices while maintaining standard protocol behavior for other devices, thereby preserving communication flexibility and fairness.

AI summary
A method and apparatus for communicating information between networked devices. Various aspects of the present invention may comprise, for example, a first networked device communicating information over a wireless communication network to a second networked device having power-save mode capability. The first networked device receives an incoming message from the second networked device. A first outgoing message is transmitted to the second networked device prior to transmitting a previously queued outgoing message. A second outgoing message is transmitted to the second networked device prior to the previously queued outgoing message being transmitted. Information may be communicated to the second networked device in a particular manner that depends on whether the second networked device has power-save capability. Communication medium access may be performed in a particular manner, depending on whether the second networked device has power-save capability.
