An ad-hoc network is a dynamically changing network of mobile nodes that communicate without the support of a fixed network. Due to lack of centralized control, secured communication in mobile Ad-hoc network is important matter due to dynamic nature of the network topology. MANETs is affected by new security problems in addition to the problems of regular networks. In this paper, the authors introduce an efficient security AODV algorithm to enhance the data security in the network. To generate the private key ECDSA algorithm is used. Simulation result shows that their protocol gives better performance than the previous one.
