Abstract
Experience with wired networks has provides guidance about what level
of detail is appropriate for simulation-based protocol studies.
Wireless simulations raise many new questions about approriate levels
of detail in simulation models for radio propagation and energy
consumption. This paper describes the trade-offs associated with
adding detail to simulation models. We evaluate the effects of detail
in five case studies of wireless simulations for protocol design.
Ultimately the researcher must judge what level of detail is required
for a given question, but we suggest two approaches to cope with
varying levels of detail. When error is not correlated, networking
algorithms that are robust to a range of errors are often stressed in
similar ways by random error as by detailed models. We also suggest
visualization techniques that can help pinpoint incorrect details and
manage detail overload.
