NAN Cluster Merging With Adaptive Scanning Intervals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The periodic scanning operations in neighbor awareness networking (NAN) for cluster discovery lead to excessive power consumption and delays in cluster synchronization due to prolonged scanning intervals and delayed information sharing.
Innovation Solution
An electronic device adjusts its scanning operation based on received information from external devices, controlling the activation and deactivation of the scanning function to reduce power consumption and facilitate timely cluster merging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the scanning operation interval is adjusted to be longer to reduce power consumption, then power consumption is reduced, but discovery of the second cluster is delayed
Solution Approach 1:
The electronic device performs preliminary actions by receiving and processing first information about the first cluster before actually discovering the second cluster. This allows the device to prepare for potential cluster merging and adjust scanning intervals proactively, reducing the impact of delayed discovery while maintaining lower power consumption through the preliminary information gathering process
2Use of energy by moving object
If the scanning operation interval is adjusted to be longer to reduce power consumption, then power consumption is reduced, but sharing of the second cluster information is delayed
Solution Approach 1:
The system implements feedback mechanisms where the electronic device receives first information about the first cluster, processes this information, and uses it to determine appropriate scanning interval adjustments. This feedback loop allows the device to optimize the balance between power consumption and information sharing timing, ensuring that cluster information is shared efficiently without excessive power usage
3Reliability
If periodic scanning operations are performed to discover adjacent clusters, then cluster discovery capability is maintained, but excessive power consumption occurs
Solution Approach 1:
The scanning operation interval is made dynamic rather than fixed. The electronic device adjusts the scanning interval based on the received first information about the first cluster and the current synchronization state. This dynamic adjustment allows the system to maintain reliable cluster discovery capability when needed while significantly reducing power consumption during periods when cluster merging is not imminent, resolving the contradiction between reliability and energy efficiency
