Abstract

The authors introduce a deterministic fluid model and two
stochastic traffic models for wireless networks. The setting is a
highway with multiple entrances and exits. Vehicles are classified as
calling or non-calling, depending on whether they have calls in
progress. The deterministic model ignores the behavior of individual
vehicles and treats them as a continuous fluid, whereas the stochastic
traffic models consider the random behavior of each vehicle. However,
all three model's use the same two coupled partial (or ordinary)
differential equations to describe the system evolution. The call
density and call handoff rate (or their expected values in the
stochastic models) are readily computable by solving these equations.
Numerical examples are presented to illustrate how the models can be
used to investigate various aspects of time and space dynamics in
wireless networks. These examples also show that the models can serve as
useful tools for system engineering and planning
