Coordinator-Based Network Communication for Redundant Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication networks experience increased congestion and interference due to multiple access points receiving redundant data from computing devices, particularly when low-powered devices using WPANs like ZigBee, Z-Wave, or Bluetooth operate in the same frequency bands as Wi-Fi, leading to overpowered data transmissions.
Innovation Solution
A coordinator device selects network devices to process data based on interference and reception levels, sending instruction signals to discard redundant data, and updates routing tables when computing device positions change.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple access points receive and forward multiple copies of data from computing devices, then data redundancy provides backup transmission paths, but network congestion and backhaul traffic increase significantly
Solution Approach 1:
The patent extracts and eliminates redundant data copies from the network traffic flow. The coordinator device identifies duplicate data packets received from multiple access points and removes them from further processing, allowing the system to maintain multiple transmission paths for reliability while preventing redundant copies from consuming backhaul bandwidth.
Solution Approach 2:
The system discards redundant data copies at the coordinator device after the first copy is processed. By identifying and discarding duplicate packets based on data identifiers, the system recovers network resources that would otherwise be wasted on redundant backhaul transmissions, maintaining reliability through selective redundancy elimination.
2Adaptability or versatility
If WPAN devices transmit data in the same frequency bands as Wi-Fi, then low-powered devices can operate in unlicensed spectrum, but their transmissions are overpowered by Wi-Fi communications
Solution Approach 1:
The coordinator device acts as an intermediary between WPAN devices and the Wi-Fi network. It receives data from WPAN devices through access points, processes the traffic, and manages transmission to the backhaul network, shielding low-powered WPAN devices from the harsh Wi-Fi interference environment while maintaining frequency band compatibility.
Solution Approach 2:
The system uses data identifiers and copying mechanisms to track and manage data packets from WPAN devices. By creating and tracking copies of data identifiers, the coordinator can identify and eliminate redundant transmissions, reducing overall network traffic and interference in the shared frequency bands.
3Reliability
If all network devices process additional data from computing devices, then data delivery is ensured through multiple paths, but redundant processing increases energy consumption and device load
Solution Approach 1:
Instead of all network devices processing additional data, the system applies partial action by having only necessary devices process data based on current network conditions. The coordinator device determines which access points should process data based on interference levels and reception quality, eliminating excessive processing by devices that would waste energy on poor-quality transmissions.
Solution Approach 2:
The system dynamically changes operational parameters of network devices based on real-time conditions. The coordinator device monitors interference levels and reception quality, then adjusts which devices process data by changing their operational state from active processing to idle, reducing energy consumption while maintaining delivery reliability through selective activation.
