Solution Overview

Problem

In wireless communication networks, especially in multi-hop networks with limited resources, unsuccessful association attempts are common due to power and time consumption of association request and rejection messages, leading to inefficient use of devices and increased processing time.

Innovation Solution

An association system where devices transmit beacon messages with load data, allowing initiators to decide whether to associate based on load data, including the number of currently associated devices, to reduce unnecessary association requests and responses, and select the most suitable target device for association.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If devices send association requests without checking load data, then association process is simple and fast, but unnecessary association requests and rejections increase power and time consumption

Engineering Contradiction:

Improveassociation process efficiencyVSAvoidpower consumption of association messages

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The association initiator device performs preliminary action by obtaining load data from the association target device before sending the association request. This preliminary check allows the initiator to decide whether to send the association request based on current load conditions, avoiding unnecessary message exchanges and reducing power consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanism where the association target device provides load data to the association initiator device. This feedback loop enables the initiator to make informed decisions about association attempts, preventing unnecessary requests when the target device is already at capacity, thus reducing both power consumption and processing time.

Inventive Principle:

Principle #23Feedback

2Productivity

If devices send association requests without checking load data, then association process is simple, but time consumption for unsuccessful attempts increases

Engineering Contradiction:

Improveassociation process speedVSAvoidtime for unsuccessful association attempts

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The association initiator device obtains load data from the association target device before initiating the association request. This preliminary action provides advance information about the target device's capacity, allowing the initiator to avoid sending requests that would likely be rejected, thereby reducing the time spent on unsuccessful association attempts.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The load data feedback mechanism enables the association initiator to make informed decisions before attempting association. By receiving feedback about current load conditions, the initiator can avoid time-wasting unsuccessful attempts and focus on suitable target devices, improving overall association process speed.

Inventive Principle:

Principle #23Feedback

3Device complexity

If router devices have limited association capacity, then network structure is simple, but all associated devices being non-router devices prevents further associations

Engineering Contradiction:

Improvenetwork structure complexityVSAvoidassociation capacity utilization

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The association initiator device performs preliminary action by obtaining load data that includes information about currently associated router devices before sending association requests. This allows the system to proactively manage association capacity and identify opportunities to associate additional router devices, improving network adaptability without increasing structural complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The feedback mechanism provides load data about current association status, including the number of associated router devices. This feedback enables dynamic decision-making where initiators can identify underutilized router devices and target them for association, thereby improving capacity utilization while maintaining simple network structure.

Inventive Principle:

Principle #23Feedback

AI summary

An association system for a wireless communication network includes an association initiator device and association target device. Each association target device transmits beacon messages including load data of the association target device including at least data indicative of number of currently associated router devices. After receiving the beacon message from an association target device, each association initiator device: decides whether to attempt to associate with the association target device on a basis of the load data included at least partly in the received beacon message from the at least one association target device, and send an association request message to each of the at least one association target device with which the association initiator device decides to attempt to associate. The application relates also to association methods for a wireless communication network, an association target device, an association initiator device, a computer program, and a computer readable medium.
