In mobile ad-hoc networks (MANETs), all nodes are treated as significant, whether it is host or router. The capability of each and every node is decided by the traffic intensity and speed of the network. The nodes are usually mobiles, which are also called as MANETs components. The type of the routing protocols decides traffic intensity and speed of the network and also the performance of the network. There are a number of routing protocols proposed for MANETs which marks it fairly difficult to find which protocol is suitable for different network situations as proposed by their quality of service contributions. The main aim of this research work is to characterize the performance of some routing protocols which are used in MANET scenarios. In order to analyze the performance of routing protocols, a simulation-based comparative study is carried out in this research work. Based on some comparisons alone, it is possible to predict the performance of routing protocols via simulation results.
