ABSTRACT: Distributed Denial of Service (DDoS) attacks in the
networks needs to be prevented or handled if it occurs, as early as possible
and before reaching the victim. Dealing with DDoS attacks is difficult due to
their properties such as dynamic attack rates, various kinds of targets, big
scale of botnet, etc. Distributed Denial of Service (DDoS) attack is hard to deal
with because it is difficult to distinguish legitimate traffic from malicious
traffic, especially when the traffic is coming at a different rate from
distributed sources. DDoS attack becomes more difficult to handle if it occurs
in wireless network because of the properties of ad hoc network such as dynamic
topologies, low battery life, multicast routing, frequency of updates or
network overhead, scalability, mobile agent based routing, and power aware
routing, etc. Therefore, it is better to prevent the distributed denial of
service attack rather than allowing it to occur and then taking the necessary
steps to handle it. This paper discusses various the attack mechanisms and
problems due to DDoS attack, also how MANET can be affected by these attacks. In
addition to this, a novel solution is proposed to handle DDoS attacks in mobile
ad hoc networks (MANETs).
