Ad-hoc mobile/802.11 networks are fully considered as networks with no fixed physical line connections. Ad-hoc networks have no fixed topology due to the movement of the end nodes. All the nodes in ad-hoc networks are mobile. Each node taking part in this network can act as host and router which can send and receive data. In this type of situations some kind of routing protocols are needed for these mobile nodes to fully operate and function properly. Ad-hoc network has some common features, which need some routing protocol. The most significant one is the dynamic routing protocols, which quickly change the topology. Reactive routing protocols search a route to destination/remote device on needed basis. Proactive protocols maintain the whole routing table at each node. In order to show the performance, NS2 network simulator has been used. The purpose of this study is to show the performance of two widely known ad-hoc routing protocols, AODV and DSR, in terms of packet delivery ratio, average end-to-end delay and routing overhead by changing the mobility. The simulation has been carried out using NS2 2.29 as the simulation platform.
