Authenticating and Securing Ad-Hoc Networks using Gateway Selection Algorithm

Wireless Ad-hoc Networks (WANETs) or Mobile Ad-hoc Networks (MANETs) are vulnerable to different sorts of threats because of their dynamic nature and absence of an essential issue of control. Collaborative attacks happen when numerous attackers synchronise their activities to upset a target network. MANET is an accumulation of nodes in versatility that co-ordinate each other forming a network through wireless connections, in which every node acts a router. The dynamic topology and self-sorting out of the nodes make them more vulnerable against the network. In MANET, the major testing undertaken is to give security amidst directing of information bundles. Different sorts of attacks have been noticed in ad-hoc networks, yet no appropriate arrangement was found for these attacks. In this research, a gateway selection algorithm has been proposed to give node authentication while a new node join the network and before initiating route discovery process in mobile ad-hoc networks. Likewise it is also demonstrated how the proposed method mitigates the effect of attacks on nodes. The result shows a better security level of about 92%. It is found to be higher than other methods
