NAN Datapath Reciprocation for Wi-Fi Coexistence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly Wi-Fi networks, face challenges in efficiently setting up and coordinating direct communication between mobile stations without an intermediate access point, leading to suboptimal performance in peer-to-peer communication.
Innovation Solution
The implementation of Neighbor Awareness Networking (NAN) allows direct communication between wireless stations, enabling reciprocating service mechanisms and multicast communication without an access point, using synchronized service windows and datapaths to facilitate peer-to-peer interactions and improve coexistence events across multiple radio access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If direct peer-to-peer communication is implemented between wireless stations without an access point, then communication efficiency and data transmission rates are improved, but setup coordination complexity and device complexity increase
Solution Approach 1:
The patent introduces a service coordinator entity that acts as an intermediary to manage and coordinate service instances between peer devices. This coordinator handles the complex setup and coordination tasks, allowing peer devices to communicate directly with simplified procedures while maintaining improved communication efficiency.
Solution Approach 2:
The patent establishes service instances and coordination mechanisms in advance before actual peer-to-peer communication occurs. By pre-configuring service windows, datapaths, and coordination protocols, the system reduces the complexity of on-the-fly setup while enabling efficient direct communication.
2Productivity
If synchronized service windows are implemented for peer-to-peer communication, then traffic congestion is reduced and communication efficiency is improved, but time synchronization requirements and system complexity increase
Solution Approach 1:
The patent implements periodic service windows at predetermined intervals for peer-to-peer communication. This periodic structure allows devices to synchronize their communication activities in advance, reducing traffic congestion during active windows while minimizing the time overhead through efficient synchronization protocols.
3Adaptability or versatility
If reciprocating service mechanisms are implemented between peer devices, then multicast communication capability is improved, but device complexity and coordination overhead increase
Solution Approach 1:
The patent creates service instances that can function as both unicast and multicast communication channels. By establishing universal service frameworks that support multiple communication modes, the system enables reciprocating service mechanisms without requiring separate complex coordination for each communication type.
