Simulation Performance of DSR Routing Protocol in MANET by Varying the Nodes Mobility

Abstract

In modernistic years, the examination field of Mobile Ad Hoc Networks has grown rapidly owing to the development of low-cost and wide-ranging wireless systems. Because of its differentiating features and broad variety of applications, MANET is becoming popular. In a MANET, nodes or access point within the propagation range of each other can deliver packets instantly, but nodes which are not in the range of each other must depend on some other node to deliver packets. Network nodes functions not only as hosts, but also as routers that transmit information to or from other network nodes. A MANET can also exhibit the multihop characteristic where “Store and Forward” mechanism is used for transmission of information. MANET’s dynamic nature opens up the network to attacks and security issues as there are distinct mobility patterns for distinct nodes. In this research article, the authors evaluate the different network performance parameters for the DSR routing protocol in a dynamic node mobility MANET environment, i.e. 20m / Sec, 40m / Sec, 60 m / Sec.
