Analysis of Security Attacks and Solution on Routing Protocols in MANETs

MANETs are fast emerging as alternate network architecture to infrastructure networks. It is finding many applications and the constraints of processing power, memory, and bandwidth will be soon being overcome with the rapid improvement in the technologies. However the major concern which will remain is the security of the network. MANETs differ largely in the routing mechanism in the network layer from other wireless networks and therefore require different security schemes to secure the routing protocols. The security of the routing protocols is the major active area of research. In this paper author analyze the routing process, their vulnerabilities and the various types of attacks which can be launched by exploiting the same, to disrupt the routing process or launch DoS attacks. The author also reviews the possible countermeasure against these attacks and listed out the advantages as well as the limitations of the countermeasures.
