This version obsoletes Technical Report 613 by surveying five more CA methods.
This version obsoletes Technical Report 620 and the ICCCN08 version by giving
a much better routing protocol, comparing the given routing protocol with the existing ones,
and explaining the basic idea more clearly.
A Real-life Meaning of this paper:
The routers in wireless mesh networks have fixed (x, y) coordinates that are accurate enough for a city area. So why not use them to assist routing?

A Real-life Meaning of this paper:
If every person has at least two random friends, when the total number of persons increases,
it becomes almost certain that any two persons are connected via a friend chain.
A Real-life Meaning of this paper:
Lazy Man: If I only aim to reach the midpoint towards the destination in each move,
can I reach the destination finally?
God: Yes, if you move on the kind of graphs called Delaunay triangulations.

Driver A: I can drive through only two streets to reach the airport.
Driver B: I can drive through ten streets but travel less kilometers than you.
Driver A: Are you kidding?
Driver B: No, if we drive on the kind of graphs called Delaunay triangulations.
