Secure Adhoc On-Demand Multipath Distance Vector Routing in MANET

Abstract

A Mobile Ad hoc Network (MANET) is a formation of the dynamic network with a group of mobile nodes and communicating through wireless links. The key issue of the mobile MANET is lack of infrastructure and resource constraint that causes fault node. Hence, MANET is exposed to dangerous attacks. In order to improve the secure routing in the network and reduce hazards by fault nodes, we enhance the existing protocol Ad hoc On-Demand Multipath Distance Vector (AOMDV) and designed routing protocol named Trusted Security Adhoc On-Demand Multipath Distance Vector (TS-AOMDV). The TS-AOMDV protocol finding and removing fault node attacks like flooding, blackhole, and grayhole attacks in the network. The detection and segregation of attacks done by using IDS and secure routing in route finding and data transmission phases. An IDS monitor data and control packets those participated in data transmission and route finding phases. In order to enhance the performance of routing in the MANET, An IDS combines and calculate data in the AOMDV for detecting attacks. This improves the TS-AOMDV to give a better performance of routing and protection in MANET. At last, the proposed protocol TS-AOMDV is evaluated with obtainable protocol AOMDV, the performance is analyzed by using the NS-2 simulator and improves routing performance like throughput by 59.1%. The result observed from a simulation that the proposed method enhances the performance of routing like as end-to-end delay, throughput, control overhead, and packet delivery ratio.
