Abstract
Simulation is the most important and widely used method in the research of Mobile Ad hoc
NETworks (MANET). The topology of MANET and the mobility of mobile nodes are the key factors
that have an impact on the performance of protocols. However, most of the existing works are based
on random movement and the fact that the network topology is highly related to the environment of
MANET is overlooked. In this paper, we propose a novel Environment-Aware Mobility (EAM) model
which models a more realistic movement of mobile nodes. Environment objects such as Route and
Hotspot are introduced to represent the environment components which are rendered by Scalable
Vector Graphics (SVG). It is considered to be a complex model with a combination of existing
conventional mobility models and network environments. This paper shows that various MANET
environments can be modeled based on this work. A sample environment is also simulated and
the results show that the intrinsic characteristics and properties of the environments have a
significant influence on the performance of MANET protocols.
