Solution Overview

Problem

In chaotic networks with mobile nodes, existing routing technologies fail to effectively determine the likelihood of packet delivery, leading to inefficiencies and disruptions due to the dynamic nature of node locations and connections.

Innovation Solution

Nodes exchange mobility information to predict future rendezvous points and calculate likelihood scores for packet interception, allowing devices to determine and optimize packet forwarding based on the highest likelihood of successful delivery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If nodes continuously move to optimize their position, then communication quality may improve, but network stability deteriorates due to changing connections

Engineering Contradiction:
Improvepacket delivery reliabilityVSAvoidnetwork connection stability
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by having nodes predict future rendezvous points and pre-calculate likelihood scores before actual packet transmission occurs. Nodes exchange mobility information in advance to determine optimal forwarding paths ahead of time, allowing the network to prepare routing decisions before topology changes happen, thus maintaining stability while anticipating reliability improvements from movement optimization

Inventive Principle:
Principle #10Preliminary action

2Productivity

If routing decisions are made based on current node positions, then routing speed is fast, but delivery reliability decreases due to rapid topology changes

Engineering Contradiction:
Improverouting decision speedVSAvoidpacket delivery reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary calculations of likelihood scores based on predicted future positions rather than current positions alone. Nodes continuously update and maintain mobility information and rendezvous predictions, so when routing decisions are needed, the system can quickly reference pre-computed likelihood scores that account for future topology changes, achieving both speed and reliability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics by making routing decisions adaptive to changing network conditions. Instead of using static routing tables, nodes dynamically adjust forwarding decisions based on real-time mobility information and predicted rendezvous points. The likelihood score mechanism allows the routing algorithm to respond flexibly to topology changes while maintaining decision-making speed through efficient probability-based comparisons

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If nodes exchange detailed mobility information, then routing accuracy improves, but network overhead increases

Engineering Contradiction:
Improvepacket arrival prediction accuracyVSAvoidmobility information exchange volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies local quality by having nodes selectively exchange and process only the mobility information relevant to their local routing decisions. Each node maintains mobility information for nearby nodes and uses likelihood score calculations focused on local packet forwarding decisions, rather than processing comprehensive global mobility data. This localized approach improves prediction accuracy for immediate routing while reducing overall information exchange volume

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the parameter representation from detailed continuous mobility trajectories to discrete likelihood scores. Instead of exchanging and processing full motion vectors, positions, and velocities, nodes exchange condensed mobility information that is transformed into probability-based likelihood scores. This parameter transformation maintains routing accuracy while significantly reducing the quantity of information that needs to be exchanged and processed across the network

Inventive Principle:
Principle #35Parameter changes

AI summary

In one embodiment, a device in a network receives packet arrival information for a packet from a neighbor of the device in the network. The packet arrival information indicates a likelihood of the packet being received by a target node that is moving in the network were the packet forwarded by the neighbor to the target node. The device forwards the packet to the target node based on a determination that the device has a higher likelihood of the packet being received by target node were the packet forwarded by the device to the target node than were the packet forwarded by the neighbor to the target node.
