Initial Overview
This summer I will be working with Dr. Baum in an effort to come up with a better
simulation model for ad hoc wireless networks. The widely used current simulation
model - Random Waypoint Model - has problems associated with it. Some problems
with this model include: (1) Nodes tend to spend most time around the middle of the
region. (2) Nodes tend to spend the most time on long links at the slowest velocity.
(3) If one starts a simulation by picking a uniform starting position, it takes a
very long time until asymptotic performance is realized. So, in an effort to come up with
a better model, two of the models that
we will examine include: (1) Random Waypoint Model with obstructions (2) Smart Random Waypoint
Model with obstructions. Obstructions in the model can block a combination of mobility and
communication. The forms of mobility blocking we will examine include: a) Total b) Partial. The forms
of communication blocking we will examine include: a) Total b) None.
