Solution Overview

Problem

Existing communication networks, such as those using the MoCA protocol, lack an efficient method for establishing beacon transmission power when responsibility is passed between nodes, leading to inconsistencies in transmission power due to varying maximum power levels and back-off values.

Innovation Solution

The implementation of a Beacon Power Protocol and control parameters like BEACON_PWRCFG_ONLY, BEACON_PWRDIST, BEACON_PWRPERSISTENCY, and HANDOFF_TO_LOWER_VEREN allows a new network coordinator node to determine and set beacon transmission power efficiently, ensuring consistent power levels and proper distribution within the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a new network coordinator node assumes beacon transmission responsibility, then beacon transmission can continue without interruption, but transmission power inconsistencies occur due to varying maximum power levels and back-off values

Engineering Contradiction:
Improvebeacon transmission continuityVSAvoidtransmission power consistency
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by having the new network coordinator node determine and set the beacon transmission power level before actually transmitting beacons. The node calculates the appropriate power level based on received power measurements and back-off values from the previous coordinator, ensuring power consistency is established in advance rather than corrected after inconsistencies occur during transmission.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the new network coordinator node measures the power level of beacons received from the previous coordinator and uses this feedback information to determine the appropriate transmission power level. This feedback loop ensures that power inconsistencies are corrected by adjusting the new coordinator's transmission power based on actual received power measurements and stored back-off values.

Inventive Principle:
Principle #23Feedback

2Productivity

If control parameters like BEACON_PWRCFG_ONLY and BEACON_PWRDIST are implemented, then beacon transmission power can be efficiently determined and distributed, but network protocol complexity increases

Engineering Contradiction:
Improvebeacon power establishment efficiencyVSAvoidprotocol structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing control parameters and procedures that serve multiple functions within the network protocol. The BEACON_PWRCFG_ONLY and BEACON_PWRDIST parameters not only control beacon transmission power but also facilitate node handovers, failovers, and power distribution across the network, reducing the need for separate dedicated mechanisms for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes parameter changes by modifying existing protocol parameters to incorporate beacon power control functionality. Rather than adding entirely new protocol structures, the invention adjusts and extends existing parameters like BEACON_PWRCFG_ONLY and BEACON_PWRDIST to handle power determination and distribution, thereby improving efficiency while minimizing the increase in overall protocol complexity.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If hierarchy for determining beacon transmission power is established, then power levels remain consistent during handovers, but information sharing requirements increase

Engineering Contradiction:
Improvepower level stabilityVSAvoidinformation sharing overhead
Core Design Contradiction:
Stability of the object's compositionVSLoss of information

Solution Approach 1:

The patent applies the intermediary principle by using control parameters and protocol messages as intermediaries to transfer power determination information between nodes. The BEACON_PWRCFG_ONLY, BEACON_PWRDIST, and related parameters act as mediators that carry necessary information during handovers, enabling power level consistency without requiring direct complex information exchange between all nodes.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements preliminary action by having nodes prepare and store back-off values and power determination parameters in advance. This pre-prepared information is readily available when handovers occur, reducing the amount of real-time information sharing needed and minimizing communication overhead while maintaining power level stability during transitions.

Inventive Principle:
Principle #10Preliminary action
