Locational Affinity Awareness
Recognize the degree of affinity between two nodes in the locational point of view
according to the measured parameters related of the physical proximity such as distance, touch, direction, etc
It may take time in measuring these parameters to get a certain recognition level

Privacy and Security
Automatic connection setup for the locational affinity awareness is not secure
Authentication should be done for some use-cases
An application considering user privacy
a group-aware application
making a random encounter into authenticated one
Identification may be inevitable to get higher security
