Solution Overview

Problem

Existing link layered wireless communication networks face challenges in optimizing throughput and routing in networks with nodes of varying capacities and capabilities, experiencing congestion and degradation due to the addition of new nodes with different characteristics, and struggle with network recovery from extreme states like power outages or intentional shutdowns.

Innovation Solution

The implementation of a System Control and Modifying Message (SCMM) that contains information on node capacity, signal strength, and utilization rates, allowing nodes to dynamically adjust their transmission parameters and routing strategies to optimize network efficiency and prevent congestion, while also stratifying the network awakening process to prevent simultaneous reestablishment of communication links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If new nodes with greater capacities and capabilities are added to the network, then node capacity increases, but network throughput optimization becomes difficult and radio message traffic increases

Engineering Contradiction:
Improvenode capacityVSAvoidnetwork throughput
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The patent implements dynamic routing algorithms that continuously adapt to changing network conditions and node capacities. The system dynamically adjusts communication paths based on real-time measurements of node capacity, signal strength, and traffic patterns, allowing the network to optimize throughput automatically as new nodes are added without manual reconfiguration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes key routing parameters including hop count, signal strength thresholds, and traffic distribution ratios to optimize network performance. By adjusting these parameters dynamically based on node capacity variations, the system maintains optimal throughput even as the network grows with nodes of different capabilities.

Inventive Principle:
Principle #35Parameter changes

2Area of stationary object

If the number of nodes in the network is increased, then network coverage expands, but radio message traffic increases causing congestion

Engineering Contradiction:
Improvenetwork coverageVSAvoidradio message traffic
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The patent segments the network into hierarchical levels or zones with different routing strategies. By organizing nodes into structured groups and implementing zone-based routing, the system reduces the number of messages that need to traverse the entire network, thereby managing radio traffic congestion as network coverage expands.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms where nodes report their status, capacity, and traffic conditions back to routing decision points. This feedback loop enables the system to dynamically adjust routing paths to avoid congested areas, optimizing message distribution as the network grows and reducing overall radio traffic congestion.

Inventive Principle:
Principle #23Feedback

3Speed

If nodes simultaneously seek to reestablish communication routes after network shutdown, then network recovery speed increases, but radio traffic congestion occurs

Engineering Contradiction:
Improvenetwork recovery speedVSAvoidradio traffic
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The patent implements preliminary actions by having nodes enter a low-power wait state after network shutdown and only gradually awaken and attempt reconnection. Nodes are configured to wait for a predetermined period before actively seeking reestablishment, and routing algorithms prepare alternative paths in advance, preventing simultaneous traffic bursts and reducing radio congestion during network recovery.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method and system for optimizing and keeping operational a wireless link layered network in which a system control and modifying message (SCMM) is elicited from nodes receiving information packets and based upon whether the node originating the SCMM is from a link layer level which is equal to or less than the link layer level eliciting the SCMM, rerouting or adjusting future transmissions can be effected or items like a current time at a receiving node and a most recent utilization rate of a receiving node can be adjusted, recorded or set.
