The Circuit of Transitions
The Circuit of Transitions represents the global movement of users within a wireless network, portraying the flow and the patterns of user transitions. The arc segments placed along a circle are access points of the given network, curved links are the transitions of users between access points. The clustering and ordering algorithms group and sort access points by relative proximity.
