Security in Mobile Adhoc Networks

Abstract

Mobile ad hoc networks (MANETs) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. Each node participating in the network acts both as host and a router and must therefore is willing to forward to packets for other nodes. The characteristics of MANETs such as: dynamic topology, node mobility, provides large number of degree of freedom and self-organizing capability of that make it completely different from other network. Due to the nature of MANETs, to design and development of secure routing is challenging task for researcher in an open and distributed communication environments. The main work of this thesis is to address the security issue, because MANETs are generally more vulnerable and we proposed a secure routing protocol for MANETs, are named ASRP (Authenticate Secure Routing Protocol) based on DSDV. This protocol is work on various modes; each mode corresponds to specific state of the node. This protocol is design to protect the network from malicious and selfish nodes. We are implementing Extended Public key Cryptography mechanism in ASRP in order to achieve security goals.
