Creation and maintaining of the one-to-one
communication link between the nodes in Vehicular Adhoc
Networks are challenging. The model which is very much efficient
for one particular scenario will not work at the same level of
efficiency for another environment. The mobility of the nodes in
the network plays a crucial role in establishing a reliable
communication model in the VANETs. Analyzing the nature of
mobility inside a particular network based on logical and
historical data paves an efficient way in the routing of packets by
predicting the best route and improve the quality of the network,
reliability, and other performance in terms of serviceability. This
paper aims to analyze the drawbacks of existing mobility models
utilizing various network quality parameters by classifying them
into microscopic and macroscopic mobility models. With the
insight gained from the analysis, we propose two methodologies
where the realistic model for the VANETs can be established. The
models are architected with the help of the information provided
by the Geographic information system. The conventional mobility
models include excessive details such as road and street layouts,
intersection with traffic signals, acceleration and deceleration,
building, and other obstacles in a realistic mobility model, that
requires prolonged time to design and optimize, it should
complicate the simulation. Designing an effective, realistic
mobility model is crucial. The key objectives of this proposal are to
architect realistic VANETs mobility models by taking into account
the real-time road environment and actual data according to the
traffic demand and improving the real-time performance of
VANETs
