Ad-hoc Wireless Mesh Network for Emergency Communication Failover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to effectively diagnose and address network failures promptly, leading to costly service disruptions and inefficient repair processes due to the loss of communication and diagnostic information when network components fail.
Innovation Solution
An ad-hoc wireless network is established to communicate network status information and provide emergency communication paths, allowing wireless access points to form connections with each other and report failures to a centralized manager, enabling immediate identification and recovery of network issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network components operate independently without backup communication paths, then device complexity is reduced, but network reliability deteriorates when failures occur
Solution Approach 1:
The patent implements preliminary action by pre-establishing an ad-hoc wireless network infrastructure between access points before failures occur. This backup communication path is configured in advance using emergency channels and subcarrier groups, allowing immediate failover when primary network components fail, thus improving reliability without requiring complex real-time decision-making during emergencies.
Solution Approach 2:
The patent uses an intermediary approach by introducing a dedicated ad-hoc wireless network as a mediator between failed network components and the centralized manager. This intermediate communication path allows diagnostic information and status data to be transmitted even when primary network paths are compromised, resolving the contradiction by adding a layered communication architecture.
2Measurement precision
If diagnostic information is continuously transmitted over the network, then measurement precision is improved, but loss of information increases when network failures occur
Solution Approach 1:
The patent applies beforehand cushioning by pre-configuring emergency communication channels and subcarrier groups that are reserved specifically for transmitting diagnostic and status information during failures. This cushioning infrastructure ensures that even when primary network paths fail, the backup paths remain available to carry critical diagnostic data, preventing information loss while maintaining continuous monitoring precision.
Solution Approach 2:
The patent extracts the critical diagnostic information transmission function from the primary network infrastructure and places it into a separate, dedicated ad-hoc wireless network. This extraction ensures that diagnostic information has its own protected communication path that is independent of the primary network's operational status, preventing information loss during failures while maintaining measurement precision.
3Reliability
If ad-hoc wireless network with emergency channels is established, then network service disruption is reduced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the wireless spectrum into distinct emergency subcarrier groups that are separate from regular communication channels. This segmentation allows the ad-hoc network to operate independently on reserved resources, reducing the complexity burden on individual access points while maintaining service continuity through dedicated emergency paths.
Data Source
AI summary
An ad-hoc wireless network is implemented by a plurality of wireless access points to detect and report failure of a concurrently implemented conventional network. The wireless access points collect and store network status information of the conventional network and send the network status information to a centralized emergency manager when failure of the conventional network is detected. The ad-hoc wireless network may also provide backhaul connectivity to a wireless access point of the failed conventional network for emergency communication.
