Mobile Ad hoc NETworks (MANETs) are basically non-infrastructure based networks with an undefined network size. This is due to the ubiquitous nature of the MANETs that allows any device to be attached to a certain network anytime. It is only limited by range of the wireless transmission. Thus, there are many problems and issues that need to be addressed for MANETs protocols. One of the main issues is the nodes movement and the dynamic change that occurs in the network topology. This paper proposed on studying the operation of MANET in an environment with varying network node densities, called heterogeneous density environment. Previous studies on the impact of MANET node density have shown that MANET operation is very dependent on the availability of neighbor nodes.
