Coordinated Channel Switch Timing in Neighborhood Awareness Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Neighborhood Awareness Networks (NAN), devices face inefficiencies in channel switching due to lack of coordinated channel switch times, leading to missed data traffic and suboptimal communication.
Innovation Solution
Introduction of a channel switch time device capability attribute to define the timing of channel switch times, allowing devices to wait for a specified interval before switching channels and ensuring data reception by including this parameter in service discovery and data path setup frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices switch channels independently without coordination, then each device can operate autonomously, but data traffic is missed and communication reliability deteriorates
Solution Approach 1:
The patent applies preliminary action by having devices exchange channel switch time information before actually switching channels. The first device determines its channel switch time and shares this information with the second device in advance, allowing the second device to prepare for the switch and ensure continuous data reception without missing packets during the transition.
2Productivity
If devices switch channels frequently to improve data transmission quality, then communication performance improves, but the complexity of coordinating switch times increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the channel switch time parameter based on data transmission requirements. When high-speed data transmission is needed, the system coordinates more frequent channel switches with precise timing information exchange. The channel switch time parameter is modified and re-exchanged to reflect new switching schedules, allowing flexible adaptation to different transmission demands.
3Reliability
If devices wait for coordinated channel switch times, then data reception reliability improves, but switching response time increases
Solution Approach 1:
The patent applies feedback by having devices exchange channel switch time information and adjust their switching schedules based on the other device's capabilities and current channel conditions. The first device determines its channel switch time, shares it with the second device, and both devices coordinate their switching based on this feedback loop, ensuring reliable data reception while optimizing switch timing.

AI summary
This disclosure describes methods, devices, and systems related to coordinating channel switch times and specifying device operation (for example, transmitting device operation) to ensure data reception by one or more devices (for example, receiving devices). A device may receive a data path setup request frame from a second device. The device may cause to send a data path setup response frame. The device may cause to establish a communication with the second device on a first channel. The device may cause to establish a communication with the second device on a second channel at a first time. The device may cause to wait, by the device, at least for a duration specified by a channel switch time (CST) parameter. The device may cause to send device data to the second device over the first channel or the second channel based at least in part on the CST parameter.
