Abstract:
The vehicular ad hoc network (VANET) has attracted a lot of attentions due to
their interesting and promising functionalities including vehicular safety, traffic
congestion avoidance, and location based services. However, using a real VANET to do
these researches costs too much. Simulation of VANET is useful and could solve this
problem well. Nevertheless, many simulations of VANET base on simple road networks
and relatively simple mobility models. Based on this road networks and mobility models,
consequently, the results of simulation of VANET would be impractical and inaccurate.
Therefore, MITSIMLAB which is a simulation of transportation system
developed by Massachusetts Institution of Technology Intelligent Transportation System
Program is introduced. In MITSIMLAB, a real world road network could be generated.
Moreover, the mobility models in MITSIMLAB are more practical. However,
MITSIMLAB is a simulation of transportation system. It cannot be used to simulate the
VANET directly, while NS2 could simulate VANET properly. NS2 is an open sourced
and free software, and it is widely used and successfully simulates plenty of situations in
the wireless environment. It could well simulate the communication protocols and
applications of VANET. But it cannot generate road network and mobility models to
simulate a practical traffic by itself.
As a result, it is important to incorporate MITSIMLAB by using its practical road
network and mobility models with NS2. In the thesis, a method about how to translate the
output file of MITSIMLAB into the format of NS2 would be proposed. In addition, a
road network based on IIT main campus is generated by using MITSIMLAB. After translating it into the format usable by NS2, a VANET based on the map of IIT main
campus and practical mobility models could be simulated.
