Abstract

Mobile Ad-hoc Network or MANET is basically a collection of mobile nodes. It is connected in a dynamic manner that is it has the property to change according to changing topology due to the lack of centralized nodes. Nodes are free to move about arbitrarily. This leads to difficult task of route maintenance in MANET. Nodes in MANET communicate with each other through various protocols. So, it is essential to identify which routing protocol works best for routing in MANET. For that we have analyzed most commonly used protocols viz AODV, DSR and DSDV on various parameters. We continue our study restricted to the AODV (Ad hoc On-demand Distance Vector) Routing protocol (since it is the most appropriate protocol for MANETs). The dynamic nature of MANET also poses a major problem for it. It is accessible to both legitimate user and attacker since it does not have a clear line of defense. A MANET becomes highly vulnerable to various attacks. The most common and prominent of all the attacks is Black Hole Attack. So we have to formulate a security solution to prevent the attacks. In order to do this, we have pre-identified all the malicious nodes in the network and then carry on routing so the network is not affected by malicious nodes and its performance not deteriorated by it. Also we make some improvements in physical nodes in order to improve the energy of nodes in the network.
