This talk is based on a paper with the same title by Tracy Camp, Jeff Boleng,
and Vanessa Davies in WCMC'02.  http://citeseer.nj.nec.com/camp02survey.html
The goal is to provide an overview of research activities in the mobility
modeling of ad hoc networks.  Some possible research topics for new graduate
students will also be described.

Abstract:

In the performance evaluation of a protocol for an ad hoc network,
the protocol should be tested under realistic conditions including,
but not limited to, a sensible transmission range, limited buffer
space for the storage of messages, representative data traffic
models, and realistic movements of the mobile users (i.e., a mobility
model). This paper is a survey of mobility models that are used in
the simulations of ad hoc networks. We describe several mobility
models that represent mobile nodes whose movements are independent of
each other (i.e., entity mobility models) and several mobility models
that represent mobile nodes whose movements are dependent on each
other (i.e., group mobility models). The goal of this paper is to
present a number of mobility models in order to offer researchers
more informed choices when they are deciding upon a mobility model to
use in their performance evaluations. Lastly, we present simulation
results that illustrate the importance of choosing a mobility model
in the simulation of an ad hoc network protocol. Specifically, we
illustrate how the performance results of an ad hoc network protocol
drastically change as a result of changing the mobility model
simulated.
