Solution Overview
Problem
Decentralized wireless networks experience downtime and reduced reliability due to broken connections between network nodes, especially in meshed networks, leading to prolonged data packet transmission failures.
Innovation Solution
Network nodes determine and forward data packets to a minimum number of other nodes and connections exceeding predefined thresholds, utilizing diverse paths and multicast communication to ensure reliable transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data packets are forwarded through a single network node to reduce transmission complexity, then device complexity is reduced, but reliability deteriorates due to connection breakdowns at that node
Solution Approach 1:
The patent segments the data transmission path by dividing it into multiple parallel forwarding paths through different network nodes. Instead of relying on a single forwarding node, the system creates multiple segmented paths so that if one segment fails, data can still flow through alternative segments, thereby resolving the contradiction between simplified transmission and reliable delivery.
Solution Approach 2:
The patent implements beforehand cushioning by pre-establishing multiple alternative forwarding paths before transmission failures occur. When a connection breakdown is detected at any network node, the system can immediately switch to pre-configured alternative paths without requiring complex real-time re routing, thus maintaining reliability while controlling complexity.
2Reliability
If data packets are retransmitted after connection breakdown to ensure delivery, then reliability is improved, but loss of time increases due to prolonged downtime
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple alternative forwarding paths and monitoring their status before actual data transmission failures occur. This allows the system to proactively detect potential connection breakdowns and switch to alternative paths in advance, eliminating the need for time-consuming retransmission operations after failures occur.
Solution Approach 2:
The patent implements feedback mechanisms where network nodes continuously monitor connection status and transmit this information back to the source node. This real-time feedback enables the system to detect connection breakdowns immediately and dynamically switch to alternative forwarding paths, significantly reducing the time loss compared to traditional retransmission approaches that only detect failures after data packets are lost.
3Reliability
If multiple network nodes forward data packets to increase path diversity, then reliability is improved, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent merges the control functions of multiple network nodes into a centralized coordination mechanism where a source node manages the selection and monitoring of multiple forwarding paths. This combining approach allows the system to benefit from path diversity through multiple nodes while avoiding the complexity of distributed coordination between all nodes, as the source node consolidates the decision-making process.
Solution Approach 2:
The patent introduces an intermediary role where the source network node acts as a mediator that selects and monitors multiple forwarding paths. This intermediary approach simplifies the system by having a single node responsible for path management rather than requiring complex peer-to-peer coordination between all network nodes, thus achieving reliable multi-path transmission with reduced coordination overhead.
4Productivity
If a single connection with high transmission rate is used to minimize transmission time, then productivity is improved, but reliability deteriorates due to connection vulnerability
Solution Approach 1:
The patent segments the data transmission into multiple parallel connections instead of using a single high-speed connection. By dividing the data flow across multiple paths with different transmission rates, the system maintains high overall productivity while improving reliability, as the failure of one connection does not completely halt data transmission.
Solution Approach 2:
The patent applies parameter changes by dynamically selecting and adjusting transmission parameters such as bandwidth allocation and path selection based on real-time connection conditions. This allows the system to optimize for both speed and reliability by routing time-sensitive data through high-speed connections while using more stable but slower connections for other data, thereby achieving both high productivity and reliability simultaneously.
