Recently, many researchers have become interested in MANET (Mobile Ad-hoc NET- works) to construct a self-con gurable network without existing communication infras- tructure. This research presents the results of a detailed performance evaluation on several MANET routing protocols working under realistic environments. The routing protocols, mobility models and other aspects are explained and discussed in order to know how to use them properly to model real-life conditions. NS-2 and Bonnmotion were used to create the networks, services and environment characteristics in general. It is concluded which protocols can handle which applications and which not and that the performance of the protocols can be considerably di erent when more and more realistic elements are taken into account. This should be considered in further researches since the nowadays evolution of MANET will bring them soon into services of our society.
