Abstract

Communication takes place by routing protocols in efficient and effective manner in wireless network. Efficient protocols are used to forward data packets without much packet loss. MANET (Mobile Ad hoc Network) because of maliciousness that intentionally disrupts the network by using variety of attacks and due to routing protocols e.g. AODV (Adhoc On demand Distance Vector), which were already developed without considering proper security features to prevent the various kinds of attacks. MANETs are frequently established in insecure environments like disaster sites and military applications. The AODV routing protocol was initially developed without considering security in mind. But there are many security schemes available that make AODV secure. However, by doing more research in this area, one major flaw in any of the existing secure routing protocols was discovered. That is security schemes that are available consume more processing power and required complex key-management system. In this work we are going to present a novel security scheme which integrates Key Distribution & Authentication Server and Secure Hash Function mechanism to protect the AODV routing protocol that is capable of defending itself against both malicious and unauthenticated nodes. The proposed security scheme will be simulated in the Network Simulator 2.
