Instead of a disk area, the floating content can be utilized to store
timely information for pedestrians visiting, e.g., a city square.
An abstract model for a city square is as follows:
- Nodes arrive to one of the corners of a rectangular area
- Upon arrival, a node moves to a random location within the square
- Upon reaching a waypoint, it chooses to exit the square with probability of Pexit by
moving to one of the corners
- Otherwise, a node chooses uniformly in random another
waypoint in the area and moves there
The figure on the right illustrates how the node density changes as
a function of parameter Pexit.
When Pexit=1, the node density is rather edgy,
and as Pexit increases the density function
approaches the density function of the RWP model.
