Prevention of DOS and Routing Attack in OLSR Under MANET

Abstract

The flourishing packets delivery up to destination is necessary for better network performance. In MANET, group of nodes is capable to create a temporary dynamic link without the support of any centralized administration and stuck infrastructure. In this research, we focus on and proposed security against DoS and routing attacks. The DoS attack and routing attack is a type of attack that are work together in dynamic network and performing misbehavior by consume link capacity and drop of data packets. However, in network if sender has begun data transmission, then in that case, both of the attackers’ mutual malicious behavior has produced a remarkable dump performance. In proposed security analysis, we proposed a novel detection and prevention security algorithm against both mutual attacks. In this research, we compare the performance of four protocols: first normal OLSR routing, OLSR routing with mutual attack, R-OLSR, and P-OLSR (proposed). The proposed scheme is able to provide secure communication and also improves the network performance. Through our proposal, we present secure as well as reliable communication in network from wormhole attack and compare the performance of different scenarios on the bases of parameters such as packet delivery magnitude relation, throughput, and routing load.
