From: Forecasting the next handoff for users moving with the Random Waypoint mobility model
Area where the node can move if next waypoint is P t in each case. The minimum distance is represented in red, while the maximum is in blue. The current direction of movement is represented by the blue arrow. The boundaries of the AP to which the node is currently associated are highlighted. The green star represents P t + v j · Δt (i.e., no change of transition during Δt).
