A New Approach of Secure Power Aware Routing for Mobile Ad-Hoc Network

Abstract

In order to assist communication within a mobile Ad-Hoc network, a well-organized routing protocol is required to determine routes between mobile nodes. Power is one of the most important design criteria for Ad-Hoc networks as batteries provide inadequate working capacity to the mobile nodes. Power failure of a mobile node not only affects the node itself but also its ability to forward packets on behalf of others and hence affects the overall network lifetime. Much research efforts have been devoted to develop energy aware routing protocols. In this paper we propose an efficient algorithm, which maximizes the network lifetime by minimizing the power consumption during the source to destination route establishment alongside making the node secure. Limited resource availability such as battery power and security are the major issues to be handled with mobile Ad-Hoc networks. By using Efficient secure routing protocol for mobile ad hoc networks that achieves secrecy of data message and secure the routing operation. The security schemes aims at preventing attacks by malicious node that intentionally disrupt the route discovery process. The protocol also assures a source node generates a route discovery request is able to identify and authenticate the route reply from destination. In mobile Ad-Hoc networks, an attacker can easily disrupt the functioning of the network by attacking the underlying routing protocol. Packets are secure during source to destination transmission by using Two Fish Encryption algorithm. As a case study proposed algorithm has been incorporated along with the route discovery procedure of AODV and PAR, by simulation it is observed that proposed algorithm’s performance is better as compare to AODV and PAR in terms of packet delivery ratio and network lifetime for different network scenarios.
