Journal of Digital Information Management Impact of Node Mobility on Manet Routing Protocols Models

A Mobile Ad-Hoc Network (MANET) is a self- configuring network of mobile nodes connected by wire- less links to form an arbitrary topology without the use of existing infrastructure. In this paper, we have studied the effects of various mobility models on the performance of two routing protocols Dynamic Source Routing (DSR- Reactive Protocol) and Destination-Sequenced Distance- Vector (DSDV-Proactive Protocol). For experiment pur- poses, we have considered four mobility scenarios: Ran- dom Waypoint, Group Mobility, Freeway and Manhattan models. These four Mobility Models are selected to rep- resent possibility of practical application in future. Per- formance comparison has also been conducted across varying node densities and number of hops. Experiment results illustrate that performance of the routing protocol varies across different mobility models, node densities and length of data paths.
