Morli Pandya, Ashish Kr. Shrivastava . Improvising Performance with Security of AODV Routing Protocol for MANETs. International Journal of Computer Applications. 78, 11 ( September 2013), 30-36. DOI=10.5120/13535-1236
Abstract
Networks are used in different fields. Its popularity has motivated the emergence of mobile ad-hoc networks (MANETs). A mobile Ad-hoc network is a decentralized wireless system which forms a fast changing network. Because of its dynamic nature and changing topology as well as wireless nature, MANET is a growing dynamic network, sometimes called mobile mesh network. MANET poses various kinds of security related problems, which are caused by their nature of collaborative and open systems and by limited availability of assets. The absence of any central coordinator makes the routing a complex one compared to traditional networks. Among various Routing protocols in Mobile Ad-hoc network, the ad hoc on demand distance vector (AODV) is most popular widely used as it has many useful characteristics. The performance will demotes when particular host or nodes fails as it sends message regarding this to source. This paper presents the performance of AODV Reactive routing protocol, along with analysis of different attacks that can be possible on AODV. It also describes two layer signature security schemes which includes secure hash algorithm which aimed at improving normal AODV performance. Here extension of AODV protocol is done, which includes secure hash algorithm and digital signature scheme aimed at further improving its security with network performance. The proposed approach is implemented by using NS2 simulator, a discrete event-driven simulator. This helps to improve the factors like performance and security.
