Cooperating Routers Using Handshakes for Interference Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The close proximity of routers often leads to wireless interference, which affects user connectivity and network performance.
Innovation Solution
Cooperating routers exchange information through a handshake to perform cooperation types such as emergency connections, bandwidth sharing, and latency optimization, utilizing inter-router communication interfaces and protocols to enhance connectivity and reduce interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If routers are placed in close proximity to improve user connectivity coverage, then network coverage and accessibility are improved, but wireless interference between routers increases
Solution Approach 1:
The patent introduces an inter-router communication interface that acts as an intermediary channel between cooperating routers. This interface enables direct communication about interference conditions and coordination of operation, allowing routers to mitigate wireless interference through cooperative decision-making while maintaining close proximity for coverage extension.
2Device complexity
If multiple routers operate independently to simplify device architecture, then device complexity is reduced, but network performance and interference coordination deteriorate
Solution Approach 1:
The patent segments the router system into independent cooperating units, each with its own control logic and inter-router communication interface. This segmentation allows each router to maintain simple individual architecture while collectively achieving improved network performance through coordinated operation via the communication interface.

AI summary
Methods and systems are provided for cooperating routers in communication networks. The cooperating routers conduct a handshake to exchange information with respect to “cooperation types” which they are capable of performing and/or are configured to perform. In an exemplary “emergency connection” cooperation type, one cooperating router may use the ISP connection of another cooperating router to send and receive packets. In an exemplary “bandwidth sharing” cooperation type, one cooperating router may make excess bandwidth available for use by other cooperating routers. In an exemplary “latency optimization” cooperation type, one cooperating router may use another cooperating router to transmit duplicates of packets or to implement suppression techniques.
