Recent advances in communication technology are enabling implementation of different types of network in various environments. One such network is Mobile Ad-Hoc Network (MANET). The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic which is done by several routing protocols. The design problem of such a routing protocol is not simple since an ad-hoc environment introduces new challenges that are not present in fixed networks. With the advent of the scenarios seeking infrastructure-less network with wireless nodes, security concerns have made the required personnel to mull over the MANET configuration using different protocols for various sized networks. This work is carried out to simulate the MANET using GloMoSim and to propose the enhancement in the quality of service by addressing the security concerns that loom on this specific network.The project discusses various categories of protocols proposed for the MANET, applications that are found out of this network, overview of the AODV protocol and most importantly the simulations that are carried out.
