NAN Anchor Master Selection via Rank and Hop Counter Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In neighbor awareness networking (NAN) clusters, the presence of multiple anchor masters can cause confusion during the anchor master selection process, as existing technologies lack clear criteria for determining the optimal anchor master.
Innovation Solution
A method and apparatus for a NAN terminal that receives a synchronization beacon frame, compares anchor master rank values and hop counter values, and updates the anchor master beacon transmission time (AMBTT) based on received values, allowing for accurate anchor master selection and reducing confusion when multiple terminals operate as anchor masters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple anchor masters operate in a NAN cluster, then the network coverage and redundancy are improved, but confusion occurs during the anchor master selection process
Solution Approach 1:
The patent applies parameter changes by introducing specific comparison criteria (anchor master rank value, hop counter value, and AMBTT value) to distinguish between multiple anchor masters. These parameter comparisons provide clear differentiation rules that resolve the confusion caused by having multiple anchor masters operating in the same NAN cluster.
2Device complexity
If existing technologies are used for anchor master selection, then the system maintains simplicity, but clear criteria for determining the optimal anchor master are lacking
Solution Approach 1:
The patent segments the anchor master selection process into distinct comparison stages: first comparing anchor master rank values, then hop counter values, and finally AMBTT values. This segmentation provides structured, precise criteria for selection while maintaining operational clarity through systematic evaluation steps.
